Construction of ZIF-8 modified laponite to enable polyvinylidene fluoride-based solid-state electrolyte with high lithium flux.

Solid-state electrolytes (SSEs) can replace the diaphragm and electrolyte in the traditional battery to solve safety perils such as electrolyte leakage and combustion, while their practical application is greatly hindered by their low ionic conductivity and poor ability to inhibit lithium dendrites. Herein, a laponite (LAP)/zeolitic imidazolate framework-8 (ZIF-8) hybrid material modified polyvinylidene fluoride (PVDF)-based composite polymer electrolytes (CPE) is reported. The in-situ modification of ZIF-8 induced by electrostatic interactions between LAP layers not only improves the dispersion of LAP, but also acts as an external bridge through hydrogen bonding with PVDF to construct a stable conductive network.
