Solid polymer electrolytes using poly(ethylene oxide) (PEO) as matrix are mostly applied due to the superior Li+ transfer ability of oxyethyl chain. However, the high crystallinity, low oxidation potential window, and insufficient mechanical strength hinder PEO deployment in solid-state batteries. Here, a novel composite solid electrolyte combined ...
