Polymer-Based Composite Electrolytes (PCEs)

About this Research Topic

Polymer-based composite electrolytes (PCEs) which combine the advantages of inorganic electrolytes and polymer electrolytes, are deemed as a promising candidate for next generation solid-state lithium metal batteries, proton exchange membrane fuel cells, direct methanol fuel cells, and so on. The satisfying PCEs are expected to possess high safety, good flexibility, excellent thermal stability, and superior electrochemical performance. However, the low ionic conductivity (lithium ion, proton, etc.) and poor electrolyte/electrode compatibility during the charge/discharge process, especially when matched with high-voltage cathodes and metallic lithium anodes, are still waiting for better solutions. Moreover, the multifunctional PCEs with unique properties such as self-healing, ultra-flexibility and anti-freezing, are also desired for applying the electrolytes in various harsh conditions. The structures, ionic conductivities, electrochemical/chemical stabilities, and fabrication of polymer-based composite electrolytes should all be considered when tackling the above issues.

Typically, PCEs can be categorized into (1) Polymer/polymer blends and (2) Composite polymer electrolyte. The components of PCEs and their fabrication approaches, influence their overall performance significantly. The effects of each component and filler type/content in PCEs are particularly important in designing high-performance solid electrolytes. Thus, the goal of this research topic is to provide advances in the field of polymer-based composite electrolytes, including the effect of their materials, fabrication, and components, on the related performance enhancing mechanisms.

This Research Topic will investigate materials, interface, system, operation and modelling of polymer-based composite electrolytes for various applications. Subjects of interest may include, but are not limited to:

• Design, synthesis, and characterization of emerging polymer composite electrolyte materials
• PCE-based device operation or optimization, covering fuel cell, batteries, etc.
• Modeling and theoretical calculation based on novel PCEs


Keywords: solid electrolyte, lithium battery, proton exchange membrane fuel cell, polymer composite electrolyte


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
