Filler‐Integrated Composite Polymer Electrolyte for Solid‐State Lithium Batteries

Abstract Composite polymer electrolytes (CPEs) utilizing fillers as the promoting component bridge the gap between solid polymer electrolytes and inorganic solid electrolytes. The integration of fillers into the polymer matrices is demonstrated as a prevailing strategy to enhance Li‐ion transport and assist in constructing Li + ‐conducting electrode–electrolyte interface layer, which addresses the two key barriers of solid‐state lithium batteries (SSLBs): low ionic conductivity of electrolyte and high interfacial impedance. Recent review articles have largely focused on the performance of a broad spectrum of CPEs and the general effects of fillers on SSLBs device. Recognizing this, in this review, after…
