Preparation of Li3PS4 solid electrolyte using ethyl acetate as synthetic medium

Phuc NHH, Totani M, Morikawa K, Muto H, Matsuda A

A precursor for Li3PS4 solid electrolyte was successfully prepared by reaction of Li2S and P2S5 in ethyl acetate. The precursor was composed of Li3PS4 and ethyl acetate in a molar ratio of 1:2, as determined by thermogravimetry-ifferential thermal analysis (TG-DTA). Upon drying at 160 degrees C, the precursor decomposed to form crystalline Li3PS4 with a high ionic conductivity of 3.3 x 10(-4) S cm(-1) and low activation energy of about 31 kJ mol(-1).
