Polymer-ceramic composite electrolytes

This paper reviews the state-of-the-art of polymer-ceramic composite electrolytes in view of three main issues, i.e., conductivity, transport number, and electrode-electrolyte interfacial reactions. These issues are believed to be critical to the development and commercialization of solid polymer batteries. The ceramic phase in limited amounts augments conductivity, enhances the cationic transport number, and suppresses electrode-electrolyte interfacial reactions. Scientific explanation for these effects is also discussed.
