Advanced Polymer Electrolytes for Fuel Cell and Lithium-Ion Battery Applications

Dear Colleagues,

Polymer electrolytes are at the forefront of innovation in electrochemical energy systems, offering unique advantages such as mechanical flexibility, a lightweight design, and tuneable ionic conductivity. As the demand for high-performance, safe, and sustainable energy technologies grows, polymer-based electrolytes have become essential components in fuel cells and lithium-ion batteries. This Special Issue aims to showcase recent advances in the design, synthesis, and application of polymer electrolytes tailored for these energy devices. We invite original research articles, reviews, and perspectives that explore novel polymer architectures, gel and solid-state electrolytes, nanocomposite systems, and interface engineering strategies. Contributions addressing ion transport mechanisms, thermal and electrochemical stability, and integration into flexible or wearable devices are particularly welcome. The Issue also encourages submissions on biopolymers and recyclable materials for green energy applications. It aims to serve as a platform for researchers to share insights and breakthroughs that drive the development of next-generation energy storage and conversion technologies. Topics of interest include the following:

• Solid and gel polymer electrolytes;
• Polymer nanocomposites and hybrid systems;
• Fuel cell and lithium-ion battery integration;
• Ionic conductivity and transport mechanisms;
• Interface engineering and stability;
• Sustainable and biopolymer electrolytes;

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly 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 2700 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.
