Polyethylene oxide) (PEO) polymer electrolytes have the potential for use in all-solid-state lithium-metal batteries (ASSLMBs). However, no effective rules been proposed to prepare PEO that overcome limitation being unusable at room temperature. In this study, based on C–H functionalization strategy, we design a highly ion-conductive electrolyte by directly covalently linking succinonitrile functional-groups with lithium coordination activity chains. The enhance disorder and mobility of chains while acting as sites fast ionic-conduction interchain, thus achieving dual optimization free volume around ions migration behavior. Due precise tuning functional-groups, functionalized exhibits enhanced ionic conductivity (>102 times), high transference number (~0.51) wide electrochemical window (~0.47 V). particular, PEO300k (1.01×10−4 S cm−1 25°C) enables stable operation temperature, providing path development polymer-based practical applications.

Abstract With the rapid development of energy storage technology, solid‐state lithium batteries with high density, power and safety are considered as ideal choice for next generation devices. Solid electrolytes have attracted considerable attention key components batteries. Compared inorganic solid electrolytes, polymer better flexibility, machinability, more importantly, contact electrode, low interfacial impedance. However, its ionic conductivity, narrow electrochemical stability window (ESW), poor mechanical properties at room temperature limit practical applications. In recent years, many studies focused on improving conductivity electrolytes; however, few systematic reviews been conducted their ESWs. A electrolyte wide will aid battery operation a voltage, which can effectively improve density. Moreover, toward metal anode is also important. Therefore, this review summarizes progress ESW, discusses factors affecting ESW analyzes strategy to broaden from perspective molecular interaction, structural design, tuning.

Poly(ethylene oxide) has been widely investigated as a potential separator for solid-state lithium metal batteries. However, its applications were significantly restricted by low ionic conductivity and narrow electrochemical stability window (<4.0 V vs Li/Li+) at room temperature.
