Fabrication and Electrochemical Characterization of an All-solid-state Battery with an Anti-perovskite Electrode Material (Li2Fe)SO

Abstract An all-solid-state battery that used (Li2Fe)SO as the electrode material without a conductive carbon demonstrated a relatively high discharge capacity of approximately 270 mAh g−1 at a high loading ratio of (Li2Fe)SO electrode (90 wt%). This study demonstrated that (Li2Fe)SO with a cubic anti-perovskite structure is suitable as a new electrode material for all-solid-state batteries.
