Abstract

A P2S5-based solid electrolyte (30P2S 5-70Li2S) was synthesized from the rapidly quenched glassy counterpart by heat treatment. The 30P2S5-70Li 2S solid electrolyte showed a high lithium-ion conductivity of about 1.0 × 10- 3 S cm- 1 at room temperature. Graphite showed reversible electrode reaction in the electrolyte A solid-state battery with the 30P2S5-70Li2S glass-ceramics, LiCoO2, and graphite as an electrolyte, a cathode, and an anode, respectively, showed steady charge-discharge cycling.
