Abstract

A solid lithium superionic conductor Li11AlP2S12 with a thio-LISICON analogous structure has been synthesized for the first time by sintering at 500 °C (LAlPS500). Such a pure lithium ionic conductor shows a conductivity of 8.02 × 10(-4) S cm(-1) at 25 °C, a low Ea of 25.4 kJ mol(-1), and a wide electrochemical voltage window of higher than 5.0 V (vs. Li(+)/Li). This facilitation of Li ionic conduction suggests the potential application in solid lithium ion batteries.
