A highly conductive and stable hybrid solid electrolyte for high voltage lithium metal batteries

A hybrid solid electrolyte (HSE) is prepared by using ionomer P(VDF-HFP)-Li x , as matrix and LATP as ceramic filler. The obtained HSE exhibits high ionic conductivity (7.88 × 10 −4 S cm −1 at 25 °C) and electrochemical stability (5.16 V vs. Li/Li + ).
