Recent Research on Polymer Composites for Energy Storage and Conversion

Dear Colleagues,

This Special Issue aims to bring together recent advances in the design, synthesis, structural characterization, and electrochemical application of polymer-based composites for next-generation energy storage and conversion systems. Rapid developments in polymer chemistry, nanocomposite engineering, and hybrid material architectures have enabled significant improvements in charge storage, conductivity, ion diffusion, stability, and device-level performance. Topics of interest include, but are not limited to, the following:

• Conductive polymers (PANI, PPy, PEDOT, etc.) and polymer-derived carbon composites;
• Polymer/metal oxide hybrid materials for supercapacitors and batteries;
• Polymer–2D material composites (MXene, graphene, hBN, MoS₂);
• Surface functionalization, defect engineering, and interface chemistry;
• Structural and electrochemical characterization (CV, EIS, GCPL, and in situ/operando methods);
• Flexible and solid-state polymer electrolytes;
• Green synthesis approaches and sustainable polymeric electrode materials;
• Device fabrication, performance optimization, and long-term cycling stability.

This Special Issue welcomes the submission of original research articles and comprehensive reviews reflecting recent breakthroughs in polymer composite design for advanced electrochemical energy systems.

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.
