Impact Factors measure how often articles in scientific journals are cited—specifically, the average number of citations received in a given year by articles published in that journal over the previous two years, as tracked in the Web of Science. For researchers, the number answers a practical question: how often is work published in this journal being picked up and built upon?

The metric is assigned to the journal as a whole, not to individual articles. A high Impact Factor tells you something useful about a journal's place in its field; it tells you less about any single paper within it.

For a complementary, article-level view, MDPI lists an Altmetric score on each article page. Where the Impact Factor tracks academic citations, the Altmetric score captures broader online attention: how an article is being shared, discussed, and referenced beyond the journal literature. Together, they offer two different ways of asking the same question: is this research reaching people?

With 2025 CiteScores from Scopus published a few weeks ago, Clarivate has now released this year's Journal Impact Factors in the Journal Citation Reports (JCR).

254 MDPI Journals Saw a Rise in Impact Factor

This year's JCR include 330 MDPI journals across a wide range of disciplines. Of these, 231 journals are placed in the top 50% (Q1 or Q2) of their respective subject categories, a result that spans fields as different as materials science, public health, environmental studies, and mathematics. 78 journals hold a top-quartile position (Q1), and 33 journals have a JIF of 5.0 or above.

• 330 journals earned a Journal Impact Factor (JIF)
• 29 journals earned a first JIF
• 254 journals had an increase in JIF
• 71% of ranked journals are in Q1 or Q2

29 MDPI Journals Received Their First Journal Impact Factor

A first Impact Factor is a confirmation for an emerging journal. It marks the point at which a journal has been publishing long enough, and cited broadly enough, to enter the formal record of scientific influence. For the research communities those journals serve, it signals that the work being published is being read and built upon.

This year, 29 MDPI journals received a Journal Impact Factor for the first time, across a range of emerging and established research areas. Each represents years of editorial development and peer review—recognized in 2026 for the first time in the JCR.

This is also part of a longer shift in how science gets indexed. When the Emerging Sources Citation Index (ESCI) launched in 2016, 24 MDPI journals were included. By 2024 that number had grown to over 200, reflecting a broader change in the visibility of open access publishing within major citation tracking systems, not just at MDPI but across the sector.

Open Access with Impact

MDPI journals have received a total of 25.2 million citations in Web of Science. That figure matters less as a measure of MDPI's reach and more as a measure of what happens when research is freely available: it gets found, read, and used. Open access is only meaningful if the work actually travels and citations are one indicator that it does.

More than 4.6 million authors have published with MDPI. That breadth, across disciplines, institutions, and geographies, is what makes open access at this scale worth doing.

Thank You to the MDPI Scholarly Community

These results belong to the people who do the actual work: the Editors-in-Chief who set the standards, the Editorial Board Members and reviewers who hold them, and the authors who choose open access for their research. The numbers in the Journal Citation Reports are the downstream effect of decisions made at the desk, in the review, and at submission. Thank you for making them.

Data: 2025 Journal Impact Factors, Journal Citation Reports™ (Clarivate, 2026)

We are pleased to share that Batteries (ISSN: 2313-0105) has received an increased CiteScore of 9.8 in June 2026, which is an impressive achievement, with the following ranks:

• Q1 (117th out of 1030, improvement) in the “Electrical and Electronic Engineering” category;
• Q1 (56th out of 347, improvement) in the “Energy Engineering and Power Technology” category;
• Q1 (16th out of 65, improvement) in the “Electrochemistry” category.

You can find more statistics on our website.

The current CiteScores measure the average number of citations within a journal over a four-year window (2022–2025). The Scopus database provides a comprehensive suite of metrics that support informed publishing strategies, research evaluation, and enable benchmarking of journal performance.

This achievement reflects the collective efforts of our authors, reviewers, and editors. Together, we will continue to track the progress of Batteries and its growing impact in the energy field.

The 2025 CiteScore metrics have been officially released by Scopus, and the results confirm what has become a consistent pattern for MDPI's journal portfolio: broad recognition across disciplines, steady improvement across the majority of ranked titles, and a growing presence at the top of subject category rankings.

CiteScore, published annually by Elsevier's Scopus database, measures the average citations received by articles published in a journal over a four-year window. As a complement to the Journal Impact Factor, which uses a two-year window based on the Web of Science database, CiteScore provides an alternative, long-term perspective on citation performance.

The 365 MDPI journals in Scopus (as of May 2026) are indexed across a wide range of subject categories, ensuring that open access research remains highly discoverable to a global readership through one of the most widely used platforms in academic publishing.

Data Summary (2025 CiteScores)

• New Additions: 41 MDPI journals received a CiteScore for the first time.
• Trending Upward: 234 of 322 previously ranked journals (73%) saw an increase in their CiteScore compared to last year.
• High Visibility: 314 journals (86%) rank in Q1 or Q2 in at least one subject category.
• Elite Performance: 42 journals rank in the top 10% of their subject categories.

Portfolio Performance

Among the 322 journals that held a CiteScore in 2024, 234 saw an increase this year. Quartile improvements outnumbered declines across the portfolio, with 52 journals moving to a higher quartile and only 20 seeing a decline. Furthermore, no previously ranked journals were removed. The 42 journals now ranked in the top 10% of their subject categories are drawn from a strong foundation of 178 journals holding a Q1 position.

With the large majority of our indexed portfolio ranked in the top half of research fields, researchers can confidently choose MDPI to meet funder mandates for high-quality, fully compliant Open Access publishing.

Exceptional Achievements for Foods and Life

Notably, both Foods and Life achieved a 99th percentile ranking in their respective subject categories for the 2025 CiteScores. This outstanding placement positions them as leading journals in their fields and highlights the high visibility and global impact of the open access research they publish.

Journal Metrics and Beyond

Journal-level metrics describe outlets, not individual articles. An increasing number of funders and institutions—including signatories of DORA and the Coalition for Advancing Research Assessment—now explicitly encourage evaluation at the article level rather than by the journal in which research appears. MDPI supports this direction: we report CiteScore alongside the Journal Impact Factor, Journal Citation Indicator, and article-level usage data because no single number captures the full reach and contribution of published research.

Thank You

These results reflect the sustained effort of thousands of editors-in-chief, editorial board members, reviewers, and authors across every field MDPI serves. The metrics are the outcome; the work is yours.

Name: Prof. Dr. Yaxiang Lu
Affiliation: Key Laboratory for Renewable Energy, Institute of Physics, the Chinese Academy of Sciences, Beijing 100190, China
Research Interests: low-cost and high-performance electrode materials; compatible and robust electrode/electrolyte interfaces; the structure–property relationships of materials; new energy storage systems such as aqueous Na/K-ion batteries

Prof. Dr. Yaxiang Lu is a professor at the Institute of Physics, the Chinese Academy of Sciences (IOP-CAS). Her research focuses on advanced electrode and electrolyte materials, interface engineering, and sodium storage mechanisms for Na-ion batteries. She has published over 80 peer-reviewed papers in leading scientific journals including Science and Nature Energy, accumulating more than 15,000 citations and an H-index of 60. Additionally, she co-authored a book titled “Na-Ion Batteries: Science and Technology”. Her recent honors include the China Youth May Fourth Medal (2026), the Batteries Young Investigator Award (2025), the China Youth Science and Technology Award (2024), the Energy Storage Materials Young Scientist Award (2023), and the First Prize of the Beijing Science and Technology Award (2022).

The following is an interview with Prof. Dr. Yaxiang Lu:

1. Could you briefly introduce yourself to our readers and tell us a little bit about your fields of interest?
I am a researcher at the Institute of Physics, the Chinese Academy of Sciences (IOP-CAS), where I focus on sodium-ion battery technology, particularly the development of key materials and underlying energy storage mechanisms. My work centers on addressing the resource limitations of lithium by advancing safe, low-cost, and high-performance sodium-based alternatives aligned with national energy strategies.
Currently, I am especially interested in the design of novel electrode and electrolyte materials for solid-state sodium batteries. The overarching goal is to simultaneously enhance energy density, cycling stability, and safety, critical pillars for the next generation of sustainable energy storage systems.

2. Could you elaborate on how you initially learned about the Batteries journal? Furthermore, what inspired you to apply for the Batteries Young Investigator Award 2025?
I first got to know Batteries when I was invited to join the journal’s Early Career Advisory Board. That role introduced me to the editorial team and the journal’s mission, and I later had the chance to attend an in-person editorial meeting, which deepened my appreciation for its community-oriented approach.
As an active researcher in solid-state batteries, I also contributed a review article on halide-based solid electrolytes, an emerging class of materials with high ionic conductivity and good stability, which was published in Batteries.
Given that our daily work revolves entirely around battery materials and devices, it means a great deal to be recognized by a journal so closely connected to our field. Receiving the Batteries Young Investigator Award 2025 is both a personal honor and a strong encouragement for our team’s ongoing efforts to develop intrinsically safe and resource-sustainable energy storage technologies.

3. Do you have any advice for aspiring young researchers looking to make a meaningful impact in their respective fields?
Focus on solving real-world problems: ground your research in genuine scientific or societal challenges. Ask yourself: Does this work address a significant gap or need? Impactful research often starts with the right question.
Cultivate original and creative thinking–don’t just follow trends. Strive to develop novel ideas, approaches, or perspectives that push boundaries. Innovation often happens at the intersection of disciplines, so stay curious beyond your immediate field.
Maintain the drive to test ideas rigorously: having a great idea isn’t enough, be willing to design careful experiments, iterate through failures, and validate your hypotheses with solid evidence. Persistence and hands-on effort turn concepts into credible contributions.
Communicate your work effectively through high-quality publications: publishing in reputable, peer-reviewed journals is essential for sharing knowledge, gaining visibility, and contributing to the global scientific dialogue.

4. What’s the secret to a happy scientific life? Have you ever encountered any difficulties conducting research and how did you overcome them?
A happy scientific life isn’t about avoiding hardship, it’s about finding meaning and growth within it. Like many researchers, I’ve certainly faced my share of challenges: repeated experimental failures, weeks or even months with no fresh ideas, moments of self-doubt, and more. What helped me most was learning to reframe obstacles not as signs of failure or inadequacy, but as natural parts of the research process. I also made a habit of seeking feedback early, breaking overwhelming problems into manageable steps, and taking time to acknowledge small victories. Often, simply talking with a trusted colleague reminded me that I wasn’t alone and that sense of connection made all the difference.

5. What is your opinion of the open access model of publishing?
I support the open access (OA) publishing model in principle, it promotes wider dissemination of knowledge, accelerates scientific progress, and ensures public access to research, especially for institutions and individuals without expensive journal subscriptions.
However, the current reliance on high article processing charges (APCs) shifts the financial burden from readers to authors, which can disadvantage researchers from low-income countries or underfunded institutions. A more equitable open access system should explore alternative funding models to ensure broad accessibility without compromising fairness.

6. Which research topics do you think are of particular interest to the research community in the coming years?
In my opinion in the coming years, key research directions in the battery community will include:

• Intrinsic safety: developing inherently stable materials and systems free from thermal runaway risks;
• Batteries for extreme conditions: enabling reliable operation under extreme temperatures, pressure, or radiation;
• Novel battery chemistries, such as solid-state K⁺/Zn²⁺/H^- batteries, multivalent systems (e.g., Mg²⁺, Ca²⁺), and dual-ion batteries, among others;
• Materials recycling and sustainability: establishing closed-loop, low-energy recycling to secure critical resources;
• AI for batteries: integrating artificial intelligence to accelerate materials discovery, interface engineering, and lifetime prediction.

7. Could you share your vision for the future of your research and the contributions you aspire to make in the field of batteries?
Looking ahead, my research aims to push the boundaries of solid-state sodium-ion batteries through several interconnected goals.
First, we are developing novel amorphous sodium-ion solid electrolytes, particularly halide- and oxyhalide-based systems that combine high ionic conductivity, wide electrochemical stability, and intrinsic safety. Paired with compatible high-capacity electrode materials, these innovations aim to significantly boost both energy density and thermal reliability.
Second, we seek to unravel the fundamental mechanisms governing ion transport in disordered solid electrolytes. Understanding how local structure, defects, and interfaces influence Na⁺ migration will guide the rational design of next-generation materials.
Finally, we are actively integrating artificial intelligence and high-throughput computational screening into our discovery pipeline. By combining data-driven approaches with targeted experiments, we hope to accelerate the development cycle of solid-state battery materials from concept to prototype in a more efficient and sustainable way.
Ultimately, I aspire to contribute practical, scalable solutions that help realize safe, low-cost, and resource-abundant energy storage for a decarbonized future.

8. As the winner of this award, is there something you want to express or someone to thank the most?
As the recipient of this award, I would like to express my deepest gratitude to several people who have made this recognition possible.
First and foremost, I am profoundly thankful to Academician Liquan Chen for his constant encouragement, visionary guidance, and unwavering support for solid-state battery research in China. His pioneering spirit continues to inspire our entire field.
I also owe immense thanks to my colleagues at the Institute of Physics, the Chinese Academy of Sciences—our daily scientific exchanges, collaborative problem-solving, and shared dedication have been instrumental to our progress.
Finally, none of this work would be possible without my students. Their curiosity, hard work, and late nights in the lab are the true engine behind every result we publish. This award belongs to them as much as it does to me.
