Research Progress and Application Prospects of Gel Electrolytes (2nd Edition)

Dear Colleagues,

We are grateful to all authors, reviewers, and readers for their responses to the first volume of our Special Issue, titled “Research Progress and Application Prospects of Gel Electrolytes”, which you can access for free via https://www.mdpi.com/journal/gels/special_issues/4638YD96UE.

We would now like to invite you to submit your work to the second edition of the issue, “Research Progress and Application Prospects of Gel Electrolytes (2nd Edition)”.

Gel electrolytes have been notable in several applications due to their unique properties. Some of these applications include batteries and energy storage systems, supercapacitors, wearable electronics, sensors, electrochromic devices, dye-sensitized solar cells, electrochemical capacitors, bioelectronics, medical devices, electrochemical analysis, and portable electronics, among others. Gel electrolytes combine the advantages of liquid electrolytes and solid components in a single system. They demonstrate improved safety, as they are less prone to leakage, flammability, and evaporation. Moreover, they have higher mechanical stability and flexibility owing to the gel’s consistency, which enables its shape and integrity to be maintained, enabling more innovative and compact device designs. In addition, gel electrolytes enhance electrochemical performance and stability by supporting ion transport, yielding a higher energy density and lifespan without dendritic growth. Lastly, they possess superior biocompatibility and tend to be more environmentally friendly than their alternatives. Despite their advantages, gel electrolytes also pose challenges related to cost-effectiveness, long-term conductivity, and scalability. Research efforts have been directed toward addressing these challenges, with the aim of making gel electrolytes more competitive with traditional electrolytes.

Thus, the main objective of this Special Issue is to highlight research works focused on gel-based electrolytes and their various applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Gels is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
