Enhancing interfacial contact in all solid state batteries with a cathode-supported solid electrolyte membrane framework

Abstract

To address the challenge of interfacial contact between the solid electrolyte and electrode with a cost-efficient solution, we demonstrate a novel cathode-supported solid electrolyte membrane framework for advanced all solid state Li ion batteries. The solid electrolyte is directly cast on the cathode layer to enhance the wetting ability of solid electrolyte onto the cathode and reinforce the interfacial adhesion. Results show that the as-fabricated LiFePO4/Li solid state battery displays superior battery performances, e.g., an initial discharge capacity of 125 mAh g-1 at 0.1C at room temperature can be achieved. The proposed electrolyte framework represent a promising strategy for mass production of high performance all solid state batteries based on Li metal anode.
