Networked Solid Polymer Electrolyte Enabling 5C Fast Cycling and Enhanced Stability of Oriented LiCoO 2 All‐Solid‐State Thin Film Batteries

Yi‐Xiu Chen, Minh Le Nguyen, Pin‐Chuan Chao, Arijit Mitra et autres

ABSTRACT Polyethylene oxide (PEO)‐based solid polymer electrolytes (SPEs) have emerged as promising candidates for advancing the all‐solid‐state lithium metal batteries (ASSLMBs) market. However, conventional PEO‐based SPEs exhibit low room‐temperature (RT) ionic conductivity and limited oxidative stability (restricted to ∼4.2 V), which impedes …
