MDPI INSIGHTS: The CEO's Letter #24 - 2024 Impact Factor & CiteScore, MDPI Summits France & USA, Tu Youyou Award

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
MDPI’s 2024 Impact Factor Highlights
For those of our readers who are new to academic publishing, you may have heard some news in June around the Impact Factor release. Every year, typically in June, Clarivate releases its annual Journal Citation Reports (JCR), which include Journal Impact Factors (JIF). This metric is widely used in academic publishing to reflect the average number of citations received by recent articles in each journal.
While Impact Factor is just one of many indicators of journal influence, it remains a major milestone for authors, editors, and publishers. It’s used to assess journal visibility, researcher recognition, and scholarly reach. Throughout our international meetings and events, it’s clear that the Impact Factor is something many of our authors and editorial board members care about, as it can influence where they choose to submit an article and the funding they receive for their research.
“These results reflect the trust that the scholarly community places in MDPI”
MDPI’s 2024 Impact Factor Highlights
- 298 MDPI journals received a Journal Impact Factor.
- 60 journals earned their first-ever Impact Factor
- To put this in perspective: MDPI’s 60 new journal acceptances into the Web of Science was the second highest number of any publisher in 2024, behind Elsevier and ahead of Springer Nature. Our 87% acceptance rate for journals submitted to Web of Science shows the strength of our editorial process and our proven ability to develop journals aligned with Clarivate’s 24 evaluation criteria.
- Notably, Textiles, Mathematics, International Journal of Neonatal Screening, Smart Cities, Systems, and Pharmaceutics ranked in the top 10% in their respective categories, highlighting their growing influence and prestige within their academic fields. This shows that high-quality indexing goes beyond visibility; it upholds credibility and trust.
- 193 MDPI journals are now ranked in the top 50% (Q1/Q2) of their subject categories.
- What does this mean, and why is it important? Journals are ranked by quartiles within their field, based on their Impact Factor. Q1 represents the top 25% of journals in their category, Q2 the next 25%, and so on. Being in Q1 or Q2 shows that a journal is performing well relative to other journals in its category. Authors and institutions often look at quartile rankings when choosing where to publish – it’s an important indicator of visibility and recognition, within its respective category.
- 116 of our previously ranked journals increased their Impact Factor.
- 14 MDPI journals achieved an Impact Factor of 5.0 or higher, suggesting a high degree of influence and visibility.
These results reflect our staff's hard work: from our editorial and production teams to our indexing, communications, and data teams, and beyond. This also reflects the trust that the scholarly community places in MDPI, reinforcing the message that when researchers publish with MDPI, they publish with impact.
Open Access with Impact
As the leading fully open access publisher, our journals have received a total of 18.4 million citations in the Web of Science by the end of 2024, reflecting the growing reach and engagement of research published with MDPI. We are committed to making scientific research freely accessible to everyone, everywhere. With the support of more than 4.2 million contributing authors, we’re proud to support the global shift toward open access.
Further Reading
If you’d like to better understand how journals get indexed and why Impact Factors matter, please read this recent interview with Dr. Constanze Schelhorn (Head of Indexing). It gives you a behind-the-scenes look at the role our indexing team plays in supporting journal indexing and visibility.
You can also read our official news announcement shared last week: MDPI Journals in the 2024 Journal Citation Reports.
Thank you to everyone, from our authors and reviewers to our editors and internal teams, who contributed to the progress of our journal indexing in 2024. We’re continuing to build journals that are recognized and trusted across disciplines.
Impactful Research
MDPI Journals See Continued Growth in 2024 CiteScore Results
Continuing our indexing updates, I’m pleased to share that MDPI has achieved strong results in the latest CiteScore metrics, released on 5 June by Scopus. These results reflect the collective efforts of our editors, reviewers, authors, and internal teams, with their dedication to quality and visibility in scientific publishing. You can read the full announcement here.
2024 Highlights:
- 322 MDPI journals received a CiteScore (up from 274 last year).
- 283 journals (88%) are ranked in Q1 or Q2 of their subject categories.
- 237 journals (85%) saw an increase in their CiteScore compared to last year.
- 48 journals received a CiteScore for the first time.
- 39 journals are now placed in the top 10% of their subject areas.
“This growth highlights our commitment to supporting open, trusted science”
What is CiteScore and how is it measured?
CiteScore metrics are developed by Elsevier as an alternative to the Impact Factor. They measure the citation impact of journals and can be accessed freely on Scopus. The metric represents the yearly average number of citations to recent articles published in a journal. If you’re interested in learning more about citation metrics and how we use them, check out this blog post.
Why is this important?
These results show the growing recognition for, and impact of, MDPI journals across disciplines. CiteScore rankings help researchers, institutions, and funders assess where high-quality work is being published. This growth improves our journals’ positioning in the publishing landscape and highlights our commitment to supporting open, trusted science.
Inside MDPI
Highlights from the MDPI USA Summit in Boston (5–6 June)
With several Summits already behind us, I think this is a good time to reflect on the purpose of these Summits.
Why do we organize MDPI Summits?
These one-and-a-half-day, invite-only gatherings are designed to improve our relationships with Chief Editors who lead our journals and are respected voices in their fields. The Summits aim to:
- Share MDPI’s values, achievements, editorial practices, and local market collaborations.
- Collect feedback on MDPI operations and journal practices.
- Empower Chief Editors to confidently represent MDPI beyond the Summit.
While Chief Editors know their journals well, these events help them better understand MDPI. We want them to be ambassadors for our brand. The aim is for them to walk away informed, engaged, and equipped to share positively about MDPI.

Coming Together for Science
Highlights from the MDPI France Summit in Paris (12–13 June)
We completed our first MDPI France Summit in Paris last week, and it was a special event. Attendees were engaged from beginning to end, remaining after hours to network and collaborate.
|
|
|
Why a France Summit?
We chose to host a France Summit in view of the recent challenges MDPI has faced with the National Centre for Scientific Research (CNRS). What we took away from the event is that our authors and editors very much appreciate and enjoy working with us, but we need to address the concerns raised by CNRS, around Article Processing Charges (APCs) and the funding of gold open access publications.
“Our authors and editors very much enjoy working with us”
Some of the claims made in the June 2023 interview with Alain Schuhl, the Deputy CEO for Science at the CNRS, are simply not factual. For example, they state that MDPI’s “average APC charges per article are now around the same as Springer Nature’s.” Here is the relevant passage, reproduced verbatim:
This is not accurate.
A recent preprint analysing APC data from Elsevier, Springer Nature, Wiley, PLOS, MDPI, and Frontiers (2019–2023) shows that MDPI’s average APCs remain significantly lower than those of Springer Nature and several other major publishers.
The MDPI Summits are part of our outreach and communication efforts to address misconceptions and clarify MDPI’s position as one of the most accessible and affordable major gold open access publishers in the world.
Summit Overview
Held on 12–13 June, the France Summit gathered over 20 Chief Editors to learn more about MDPI’s activities and collaborations in France. Many of these editors are influential in their institutions and professional societies. Several also have connections to CNRS, which makes this an important opportunity to clarify how we operate and build trust through open and transparent communication and hopefully turn our editors into informed advocates of MDPI.
Summit Feedback
The feedback has been very positive, with most attendees completing the post-event survey and all rating the experience as Excellent or Good. A few highlights:
- “The whole thing was highly professional and, above all, provided quantified details that will allow us to better answer questions surrounding MDPI.”
- “The summit was an opportunity to meet personally various people directly engaged in the organization and policies of MDPI, which made it possible to clarify some important points concerning publishing with MDPI.”
- “Very well organized! A great opportunity to see all French MDPI partners and editors.”
Program Highlights:
Moderated by Miruna Adelina Nicolcioiu (Senior Conference Producer), the program featured:
- MDPI Overview and France Collaboration – Stefan Tochev (CEO)
- MDPI Editorial Process and Peer-Review Quality – Dr. Marta Colomer (Public Affairs Specialist)
- Institutional Partnerships and Open Access Funding Models – Becky Castellon (Institutional Partnerships Manager)
- AI in Publishing and MDPI's Actions – Daniele Raimondi (Data Scientist)
- Publication Ethics: Global Trends – Diana Cristina Apodaritei (Research Integrity Specialist)

Batteries | Interview with the Author—Dr. Hiroyuki Ueda
Dr. Hiroyuki Ueda’ published paper:
“A Polymer-Binder-Free Approach to Creating Functional LiFePO4 Cathodes by Organic Ionic Plastic Crystal-Derived Ion-Conductive Binders”
by Daniela M. Josepetti, Maria Forsyth, Patrick C. Howlett and Hiroyuki Ueda
Batteries 2025, 11(1), 3; https://doi.org/10.3390/batteries11010003
Available online: https://www.mdpi.com/2313-0105/11/1/3
Name: Dr. Hiroyuki Ueda
Affiliations: 1 Institute for Frontier Materials (IFM), Deakin University, 221 Burwood Highway, Burwood 3125, Australia;
2 Battery Research and Innovation Hub, Deakin University, 5/154 Highbury Road, Burwood 3125, Australia.
Research interests: batteries, electrochemistry, electrode slurry preparation, slurry coating, voltammetry, ionic liquids, fullerenes
The following is a short interview with Dr. Hiroyuki Ueda:
1. Could you introduce yourself or your research group?I am an Alfred Deakin Postdoctoral Research Fellow at Deakin University (Australia). I received my Ph.D. degree (Doctor of Engineering) from Kumamoto University (Japan) in 2016. After my graduation, I worked in the research and development divisions of three companies in the chemical and automotive industries, where I contributed to many projects on lithium-ion and solid-state batteries (SSBs). In 2020, I joined my current research group (Electromaterials, Institute for Frontier Materials, Deakin University) as an Associate Research Fellow and was fully committed to the Linkage Project (grant number: LP180100674) with Toyota Motor Corporation for the development of SSBs using an emerging class of solid electrolytes known as organic ionic plastic crystals (OIPCs). I was a lead CI on its subsequent industry project until March 2023, while helping with selecting and sourcing battery materials, tools, and pilot-scale manufacturing instruments for a newly built Australian unique battery-prototyping facility called Battery Research and Innovation Hub (https://batteryinnovationhub.com.au). Following this, I was awarded a research fellowship to be in my current position. Now I have been developing OIPC-containing solid-electrolyte membranes and electrodes for battery applications (mainly for SSBs).
The Electromaterials group at Deakin University is a diversified, multidisciplinary research team with >50 people, including professors, associate professors, research, technical, or administrative staff members, Ph.D. students, and research interns. We have been tackling many research questions in the energy sector by leveraging the group’s extensive expertise in material modelling, synthesis, and characterisation; battery implementation, testing, and demonstration from the laboratory to pilot scale; and metal recovery. The group was established in 2010 and was formerly led by Prof. Maria Forsyth, who has significantly contributed to research on energy materials, especially ionic materials, including ionic liquids, OIPCs, and solid polymer electrolytes. The group has continually reported groundbreaking findings for multiple battery formats, including lithium-ion, lithium-metal, sodium-ion, sodium-metal, zinc-air, and SSBs. Among them, my team has mainly focused on the development of SSBs to provide breakthrough energy-storage options.
2. Please share what inspired your research?
Our paper demonstrated the use of OIPC−Li salt binary mixtures (hereafter referred to as OIPC electrolytes) as binders in the electrode layer for the first time. This approach was inspired by my previous discovery in graphite−OIPC composite electrodes (Batter. Supercaps, 2022, 5(7), e202200057); containing OIPC electrolytes in the electrode composition minimised the changes in the state-of-charge-dependent resistances of the electrodes, which implies that OIPC electrolytes can stabilise particle−particle and particle−current-collector contacts. This would be the additional benefit of using OIPC electrolytes as their intended function is mainly ion conduction in SSBs. Therefore, I was motivated to investigate the binding properties of OIPC electrolytes in this paper. We deliberately removed the polymer binders from the electrode layer so that we could clarify this point by the achievable electrode parameters (i.e., theoretical areal capacity and electrode density) and battery performance (i.e., cyclability).
3. In your career of battery research, which mentor or predecessor has had the greatest influence on your scientific thinking? How does this influence reflect on the writing style of this paper or the choice of research path?
Since I came back to academia, Prof. Maria Forsyth and Prof. Patrick C. Howlett have served as mentors for me. I have been fortunate to receive countless pieces of invaluable advice from them throughout my research career. Prof. Forsyth’s everlasting passion towards scientific understanding and development has often reminded me of the importance of consistently advancing research activities with enthusiasm, even if I face the chains of unsuccessful experimental results. In addition, Prof. Howlett’s forward-thinking approach has helped me form novel research ideas and assisted in shaping pragmatic solutions for any difficulties in research activities. Both distinguished researchers in the battery field have significantly influenced my research philosophy. Owing to their support, I was able to believe in my research path, overcome many challenges associated with this paper, and succeed in demonstrating the idea of using OIPC electrolytes as ion-conductive binders in electrodes.
4. Why did you choose to publish with Batteries, and how was your experience?
This was because I had an invitation to submit a research paper to Batteries, and their editorial team was generous to consider options to accommodate the standard article processing charge after reviewing the previous pre-printing version of the paper (https://doi.org/10.20517/scierxiv202408.01.v1) and its potential impact if published. Batteries is one of the well-known journals in the energy sector. Their peer-review process was fast and accurate; I received many suggestions from reviewers and addressing them surely improved the quality of the paper. The proofreading process after peer review was also fast, ensuring the speedy dissemination of scientific findings. Moreover, the Editorial Office was happy to announce the publication of this paper on their social media and chose my research for the cover of their January 2025 issue (https://www.mdpi.com/2313-0105/11/1). Overall, I have been satisfied with the journal’s strong support for fast-paced publication with high-quality papers and assistance in forming its impact on the battery community.
5. What was the biggest challenge you faced while writing this paper, and how did you overcome it?
The electrode preparation for this paper was done before the establishment of the Battery Research and Innovation Hub in mid-2022 and, therefore, Daniela (+MESC master’s student at that time) and I had to develop a reliable method to generate homogeneous electrode slurries without using a planetary centrifugal mixer that is commonly used for this purpose. We did multiple trials using many small-scale instruments (including magnetic stirrers) and finally concluded that ball-milling with a few ZrO2 balls allows us to prepare homogeneous electrode slurries (without unnecessarily crushing electrode materials). Although another preparation method would be beneficial in improving theoretical areal capacity for reference polymer-binder-containing electrodes, this approach enabled reliable comparisons in performance metrics between resulting polymer-binder-free LFP−OIPC electrodes with different compositions in this paper.
6. How did feedback during your research influence your direction?
Feedback from my research team and reviewers’ comments on earlier versions of the paper were important in refining the methodology of experiments as well as the way of presenting research findings. For instance, we successfully proved the structural stability of polymer-binder-free LFP−OIPC electrodes by showing their intactness in liquid electrolyte solutions; the concept of this experiment was mutually formed through multiple discussions within the team. On the other hand, we were able to explain many advantageous features of our polymer-binder-free approach (when compared to the conventional polymer-binder-containing composition) after revision. We did additional experiments to address reviewers’ comments, which effectively correlated the electrode’s processability with the physical state of OIPC electrolytes. Therefore, I feel that consistent teamwork and peer reviews greatly improved the significance and potential impact of the paper.
7. What are the current challenges in the battery research field, and how can they be addressed?
There are many ongoing challenges in battery research. For instance, there is a trade-off between the safety and energy density of batteries; the more active materials can store energy, the more risk these batteries inherently have (e.g., thermal runaway when shorted). Although many researchers have been studying metal anodes intending to exploit their exceptionally high theoretical capacity, a strong tendency of metal–dendrite formation hampers their widespread applications in real-world rechargeable batteries. “Anode-free” configurations partly improve battery safety, but their reversible operation relies on the plating/stripping of metal species and, therefore, safety issues associated with metal anodes have yet to be overcome intrinsically. In this respect, battery chemistries without plating/stripping might be highly sought after; these include intercalation/deintercalation reactions (e.g., well-known for graphite), alloying/dealloying reactions (e.g., for Si), and redox reactions in general. My research team has demonstrated the versatility of composite electrode formulations with non-flammable OIPC electrolytes across a wide range of active materials for SSBs, which not only includes conventional materials (e.g., LFP, LiNixMnyCo1−x−yO2, graphite, and Li4Ti5O12) but also high-capacity materials (e.g., Si, and conversion cathode material: Chem. Mater. 2024, 36(15), 7222–7231). Therefore, I believe one of the possible solutions to balance safety and energy density is employing the SSB format with thermally stable solid electrolytes (e.g., OIPC electrolytes) and high-capacity materials. I hope the ongoing research in my team will generate many fruitful findings to address this point.
This is my first last-corresponding-author paper where I contributed to most aspects of the paper preparation and handling from the beginning. I consistently helped Daniela with her experimental progress and assisted her with manuscript drafting through multiple discussions about possible story flow and key findings that we needed to write. Daniela successfully drafted the first version of the manuscript from scratch, and I took over further writing with some additions of new sections. Prof. Forsyth and Prof. Howlett joined some discussions within the team and advised us on further experimental investigations, which ensured that the paper’s narrative did not fully rely on assumptions and helped construct discussions based on actual data. I think our teamwork significantly enriched the paper’s quality, and I hope it provides useful insights into the development of OIPC-containing electrodes for battery applications.
9. What trends and technologies do you see shaping the future of battery technology?
Other than the safety and energy-density limitations mentioned earlier, I think the focus on developing battery technology has been gradually shifting towards more sustainable options. For instance, many researchers have started investigating electrode-preparation methods without using a harmful solvent (e.g., N-methyl-2-pyrrolidone), which includes water-based slurry preparation and electrode manufacturing without any solvents (i.e., dry process). These will potentially reduce the environmental impact of the current production steps. Another example is replacing synthetic polymers in batteries with bio-based ones. This makes resulting batteries more eco-friendly and potentially simplifies their recycling processes (e.g., by dissolving the polymer separators in water for separation, whereas polyethylene or polypropylene separators are relatively hard to separate). My research team has also been studying some sustainable approaches using OIPC electrolytes, and I hope I can disseminate relevant publications in the near future.
10. What impact do you hope your research will have, and what key innovation do you see in your paper?
Our paper clearly showed the three advantages of the polymer-binder-free approach over the conventional polymer-binder-containing electrode formulation: (1) A higher active-material loading without crack formation in the electrode layer, (2) a lower electrolyte amount in the electrode layer, and (3) a higher Coulombic efficiency during battery operation. Although I must admit that the cyclability of polymer-binder-free LFP−OIPC electrodes in this paper was not as good as that containing a polymer binder, this would potentially be solved when the electrodes are tested in SSBs. Through this study, we have demonstrated the dual functionalities of OIPC electrolytes as both ion conductors and binders, which lays a robust foundation for further development of OIPC-containing electrodes.
The paper was featured as the journal cover (https://www.mdpi.com/2313-0105/11/1) with an impressive scientific illustration for the top view of a polymer-binder-free LFP−OIPC electrode, which visually intensifies these two roles as the pre-built Li+-conduction pathways and intricate networks formed by the OIPC electrolyte. I would like to acknowledge Hibiki Asahori (https://www.hibikiasahori.com) for creating this cover illustration and The Fujikura Foundation for supporting this cost. I hope the journal cover will attract readers’ attention and encourage studies on innovative electrode formulations (e.g., composite electrodes with pre-filled electrolytes) for advanced rechargeable batteries.

Name: Dr. Diogo M. F. Santos
Affiliation: Center of Physics and Engineering of Advanced Materials, Laboratory for Physics of Materials and Emerging Technologies, Chemical Engineering Department, Instituto Superior Técnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal
Research interests: industrial electrochemistry; electrochemical engineering; direct borohydride fuel cells; direct liquid fuel cells; alkaline water electrolysis for hydrogen production; electrochemical wastewater treatment.
The following is a short interview with Dr. Diogo M. F. Santos:
1. Could you introduce yourself or your research group?My name is Diogo M.F. Santos, and I am a principal researcher and invited Assistant Professor at the Instituto Superior Técnico of Universidade de Lisboa (Portugal). Our research group, GEECS: Group on Electrochemical Energy Conversion and Storage, is part of the Center of Physics and Engineering of Advanced Materials (CeFEMA). We are developing electrode materials and separators for application in electrochemical energy conversion and storage devices, including electrolyzers, fuel cells, batteries, and supercapacitors.
This work has been developed in the scope of the Ph.D. studies of my student João Rodrigues, who is producing organic electroactive materials for next-generation aqueous rechargeable batteries.
2. What was the biggest challenge you faced while writing this paper, and how did you overcome it?
This work’s biggest challenge was understanding the differences in electrochemical behavior between tetrathiafulvalene and its derivatives. By analyzing the reaction order for each peak and doing an in-depth literature search, we started understanding the reasoning behind these differences. Further studies will involve both experimental and computational methods.
3. What are the current challenges in the battery research field, and how can they be addressed?
In a broad sense, there is an urgent need to find alternatives to lithium-ion batteries to reduce the environmental impact of battery production and avoid future problems with lithium supply shortages.
In the specific case of small-molecule organic electrode materials, finding materials with good performance without requiring the addition of conductive additives continues to be a common problem. Additionally, cyclability problems hinder the ability of these organic electrode materials to be commercialized. These problems can only be addressed by continuing to synthesize and test new materials, building on the knowledge we have of rational design for organic materials for electrochemical applications.
4. What trends and technologies do you see shaping the future of battery technology?Research on battery chemistries alternative to lithium-ion batteries, for example, sodium-ion, potassium-ion, or multivalent ions like zinc-ion, will continue to grow in prominence as these alternative chemistries could have a large impact in terms of battery cost and sustainability, and in some cases could even lead to higher energy density energy storage devices.
A shift to aqueous batteries is also possible, as several strategies to increase water’s electrochemical stability window and allow for higher energy density aqueous batteries are being refined.
5. What impact do you hope your research will have, and what key innovation do you see in your paper?This research may contribute to the development of better energy storage devices, whether it be by making them cheaper, more environmentally friendly, safer, faster charging, or more energy dense. The main innovation in this work is the combination of the studied electrode materials and the used electrolyte. Derivatives of tetrathiafulvalene have been rarely studied in aqueous electrolytes for battery applications.

Dr. Antal Jákli and Mr. Zakaria Siddiquee’s published paper:
“Plasticized Ionic Liquid Crystal Elastomer Emulsion-Based Polymer Electrolyte for Lithium-Ion Batteries”
by Zakaria Siddiquee, Hyunsang Lee, Weinan Xu, Thein Kyu and Antal Jákli
Batteries 2025, 11(3), 106; https://doi.org/10.3390/batteries11030106
Available online: https://www.mdpi.com/2313-0105/11/3/106
Name: Dr. Antal Jákli
Affiliation: Department of Physics and Materials Science, Advanced Materials and Liquid Crystal Institute, Kent State University, Kent, OH 44242, USA
Research interests: ferroelectric nematic liquid crystals (FNLCs), ionic liquid crystal elastomers (iLCEs) and chiral liquid crystal lenses, the use of iLCEs in actuators, sensors, transistors and batteries, and the use of LC lenses in virtual reality
Name: Mr. Zakaria Siddiquee
Affiliation: Department of Physics, Kent State University, Kent, OH 44242, USA
Research interests: the intersection of advanced materials science, electrochemistry, and computational modeling, with a focus on developing next-generation energy storage and low-power electronic devices
How could plasticized ionic liquid crystal elastomer emulsion-based polymer electrolytes enhance the safety and performance of next-generation lithium-ion batteries? Let’s read about Dr. Antal Jákli and Mr. Zakaria Siddiquee’s ideas.
1. Could you introduce yourself or your research group?
My name is Antal Jákli with 40 years of experience in soft matter physics with a special emphasis on liquid crystals. My current research group focuses on the fundamental and applied science of liquid crystal materials, with applications spanning optical devices, electrochemical systems, and smart materials. Recently, we have started a project on the studies of ionic liquid crystal elastomers. We have shown that they can be used for low-voltage actuation, to generate flexo-ionic currents, and to be used in Organic Electromechanical Transistors. Two years ago, I assigned one of my students, Zakaria Siddiquee, then a 3rd-year Ph.D. candidate in the Department of Physics at Kent State University, to explore their use as electrolytes in batteries. Our goal was to enhance the performance and safety of next-generation solid-state battery technologies.
2. Please share what inspired your research?
The inspiration for our current research originated from a collaborative effort between my group, Thein Kyu and Weinan Xu from the Department of Polymer Engineering at the University of Akron on ionic liquid crystal elastomers as actuators and electric current generators. Dr. Kyu has long-term experience with polymer-based solid-state batteries gave me the idea to extend our collaborative work to novel solid-state batteries using ionic liquid crystal elastomers as electrolytes. As liquid crystal elastomers shrink on heating, they offer mechanical stability against overheating. Additionally, their anisotropy also offers much more efficient ion transport than conventional isotropic polymer electrolytes.
The corresponding author, Antal Jákli has published over 300 articles in international peer-reviewed journals, has over 20 patents, and also published one textbook (https://scholar.google.com/citations?user=JsWVWfkAAAAJ&hl=en&oi=ao). For the first author, Zak Siddiquee this is his 2nd publication. He also has a patent application for this battery technology.
The reason to publish in the journal Batteries was an invitation received by Jákli to submit a manuscript, and that Thein Kyu already had a positive experience publishing one of his previous works in this journal. Batteries provided a clear and structured submission process, with well-defined formatting guidelines and a strict timeline—not only for authors but also for reviewers. We found the tight scheduling especially helpful. It allowed us to better plan and execute experiments efficiently, and it ensured that the overall progression of the paper remained on track. We would gladly consider publishing there again in the future.
3. What was the biggest challenge you faced while writing this paper, and how did you overcome it?
As this was the first publication in the field of battery research for both Siddiquee and Jákli (for the 1st and corresponding authors), the challenges we faced were to learn the proper experimental techniques and effectively articulate the novelty of our work—specifically how our liquid crystal elastomer differs from conventional polymers used in batteries. Fortunately, we had strong support from our collaborators at the University of Akron, who are highly experienced in polymer and battery research. Zak had the opportunity to work closely with Hyunsang Lee during the first year of his work, and that experience shaped many aspects of his approach to battery research. Lee was instrumental in teaching Zak the foundational skills required for this field, including the characterization of electrolyte properties, battery assembly, and safe operation of glovebox systems.
4. What are the current challenges in the battery research field, and how can they be addressed?
While we can’t speak for the entire battery research field, one of the major challenges in solid polymer electrolyte systems is low ionic conductivity. These materials often exhibit high theoretical capacity, but their limited charge/discharge rates prevent full utilization of that capacity, which significantly impacts performance, especially in high-power applications. Our research suggests that material anisotropy could offer a promising pathway forward. Traditional polymer electrolytes are isotropic and lack directional control over ion transport. In contrast, liquid crystal elastomers offer a unique advantage: they can be aligned to create anisotropic structures, introducing a new tunable parameter that can be engineered to enhance ionic pathways. By leveraging this property, we aim to develop electrolytes with improved ionic conductivity and overall electrochemical performance.
5. What trends and technologies do you see shaping the future of battery technology?
With the rapid advancement of artificial intelligence, wearable electronics, and increasingly powerful portable devices, the demand for high-performance, safe, and compact energy storage solutions is greater than ever. This growing need is pushing innovation in both materials and design. One trend we find especially promising is the shift toward flexible, non-flammable solid polymer batteries. We believe that, in the near future, we may see batteries integrated seamlessly into device enclosures, for example, having the phone case itself function as the battery.

Batteries | Interview with the Author—Dr. Ashley Willow
Dr. Ashley Willow’s published paper:
“Design and Validation of Anode-Free Sodium-Ion Pouch Cells Employing Prussian White Cathodes”
by Ashley Willow, Marcin Orzech, Sajad Kiani, Nathan Reynolds, Matthew Houchell, Olutimilehin Omisore, Zari Tehrani and Serena Margadonna
Batteries 2025, 11(3), 97; https://doi.org/10.3390/batteries11030097
Available online: https://www.mdpi.com/2313-0105/11/3/97
Name: Dr. Ashley Willow
Affiliation: Department of Chemical Engineering, Faculty of Science and Engineering, Swansea University, Swansea SA1 8EN, UK
Research interests: sodium-ion batteries, lithium-sulfur batteries, “Anode Free” batteries, surface science, platinum electrochemistry, oxygen reduction, etc.
The next battery revolution? Dr. Ashley Willow shares cutting-edge research on Prussian white cathodes for anode-free systems. Below is a short interview with the author.
1. Could you introduce yourself?My name is Ashley Willow and I hold a B.Sc. chemistry, M.Sc. Ccatalysis, and Ph.D. electrochemistry. I am a Senior Lecturer at Swansea University in the Department of Chemical Engineering and research within the Circular Approaches to Utilize and Retain Energy (CAPTURE) Centre of Expertise. My current research focus is on the understanding of traditional sodium-ion batteries and those that operate in the so-called “anode-free” format. I have a background in pouch cell assembly and have established pouch cell and cylindrical cell production facilities at Swansea University. I focus on understanding the issues associated with the transfer from coin cell to commercial cell formats in these chemistries. Before my most recent position at Swansea University, I spent several years in industry in the fields of post lithium-ion batteries (Lithium Sulfur) and investigating the electrochemistry of steel. I organized the international Sodium ion conference at Swansea University (STRIKE) and led the scale-up research efforts on sodium-ion anode-free cells.
2. Please share what inspired your research?A few key contributing factors inspired this research in particular. Firstly, working in the industry on pouch cell assembly and energy density calculations gave me key insights into how cell design influences energy density. I wanted to apply this experience to sodium-ion batteries, in particular to the relatively new area of sodium-ion anode-free batteries by realistically demonstrating the potential of this technology. I hope this work can guide the development of sodium ion anode-free and help bridge the industry-academia gap. This thinking led to the development of our open cell calculator (WattCell · Streamlit), a key outcome of the publication. Another inspiration is the rapid growth in understanding and application of sodium-ion batteries, which pushes everyone in our group to be part of this rapidly growing field.
3. In your career in battery research, which mentor or predecessor has had the greatest influence on your scientific thinking?I have been very lucky to have many great mentors and colleagues in academia and industry who have influenced me in different ways. My Ph.D. supervisor, Prof. Gary Attard, was hugely influential at the start of my career. His enthusiasm for experimental and fundamental electrochemistry sticks with me to this day. In industry, colleagues and mentors at OXIS Energy Ltd. fostered an environment of open scientific debate and discussion, which I continue to uphold. I currently work closely with many colleagues at Swansea University and, in particular, note Prof. Serena Margadonna’s influence. She encourages scientific rigor and ambition in battery research.
4. Why did you choose to publish with Batteries, and how was your experience?I particularly chose Batteries as the topic was well suited, especially concerning the Special Issue. The experience was very positive. Writing using the provided templates was straightforward, updates were clear and regular, the reviewer comments were helpful, and I am very happy with the final publication.
5. What role did you play in your research team, and how did teamwork affect the paper’s outcome?Teamwork was an essential pre-requisite of this work, which is true of most battery research due to its multidisciplinary nature. We required high-quality cathode synthesis (Dr. Sajad Kiani), coating and online cell calculator development (Dr. Marcin Orzech), and pouch cell assembly (me), to name a few factors. Without bringing these aspects together the paper would not have been possible.
6. What trends and technologies do you see shaping the future of battery technology?Sodium-ion batteries will be hugely influential in the next decade. The commercial developments are essentially locked in due to efforts from large battery manufacturers and recent breakthroughs in energy density and cycle life. Sodium ion batteries are very suited for low-cost storage in a number of applications so the proliferation of this technology will expand naturally. I see sodium ion anode-free technology as very promising; the stack pressure requirements are lower than the lithium metal anode-free equivalent and they offer better cycle life also (although the literature in this area is sparse). Due to the removal of hard carbon, anode-free offers energy density advantages compared to intercalation-based sodium-ion batteries. Investigations to further improve the cycle life of anode-free are ongoing and could hugely shape the commercial direction of battery technology.
7. What impact do you hope your research will have, and what key innovation do you see in your paper?This article gives a clear direction in moving from single-layer pouch cells to multilayer cells with reasonable energy densities using a battery format (anode-free) that has growing research attention. This is the first demonstration of Prussian white-based sodium ion anode-free pouch cells and the start of the innovation process.
