Advanced Flexible Membranes for Next-Generation Electrochemical Energy Devices

Dear Colleagues,

High-performance and robust membranes/separators are needed for the variety of electrochemical energy devices (EEDs). Depending on the type of EED, the design attributes and desired characteristics of an ideal membrane will vary. In particular, for next-generation EEDs (e.g., solid-state lithium batteries, metal–air batteries, hybrid flow batteries, and Li–CO₂ batteries), the development of highly conductive, selective, and stable membranes with high mechanical flexibility is of significant importance. Furthermore, some of these EEDs may need to be designed for portable/wearable electronics, which further limits the design domain for such membranes.

Polymeric and hybrid polymer–ceramic membranes are usually very attractive choices for these classes of electrochemical energy storage/conversion devices. Not only does the polymer structure provide a tunable design framework, but the electrochemical and mechanical properties of these membranes can also be precisely engineered via functionalization, and by implanting various fillers (e.g., ceramic particles) within the polymer matrix. In addition, the capability of manufacturing such membranes using high-throughput manufacturing technologies (e.g., extrusion, 3D printing, and roll-to-roll (R2R) atomic layer deposition (ALD)) makes them even more desirable for large-scale production.

Considering the critical role of this class of flexible membranes in enabling next-generation EEDs, this Special Issue is dedicated to the application of these membranes in such devices. We also welcome the submission of recent works on the design and synthesis of novel and mechanically flexible membranes, as well as critical review papers from top and emerging research groups.

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. Membranes 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 2200 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.
