All-solid-state batteries using Li2S-P2S5 solid electrolyte and LiFePO4 glass ceramic electrode particles were constructed. The batteries were charged and discharged with reversible capacity of 110 mA h g(-1). Amorphous oxide surface layer formed on LiFePO4 glass ceramic particles improved interfacial properties between LiFePO4 electrode and Li2S-P2S5 solid electrolytes.
