Abstract

Na3PS4-based materials, which have relatively high conductivities and favorable mechanical properties, make promising Na-ion solid electrolytes for realizing all-solid-state sodium batteries. In this study, Na3-xPS4-xClx solid electrolytes power is prepared by a mechanical ball milling process and subsequent heat treatment process using low-cost Na, NaCl, P2S5 and S as raw materials. In addition, we investigate the conductivity and electrochemical of the composite solid electrolyte with polyethylene oxide-NaClO4. The results show that Na3-xPS4-xClx solid electrolyte heated at 500℃ with polyethylene oxide-NaClO4 exhibits Na-ion conductivity of 8.75×10-4 S cm-1.
