US 2017/0317382 A1 · BATTERY MADE FROM A SINGLE MATERIAL

Abstract

A solid-state lithium-ion battery may include an anode, a solid electrolyte layer of material, and a cathode. Each consist of the solid electrolyte material and are interspersed with a current collector material such that electrical conductivity is enabled between the anode and the cathode via the solid electrolyte layer to form a solid state lithium ion battery made from a single material in common to the anode, the solid electrolyte layer and the cathode. A method of manufacturing a solid-state lithium-ion battery includes cold pressing Li10GeP2S12/C anode composite layer, LGPS solid electrolyte layer, and Li10GeP2S12/C cathode composite layer to enable electrical conductivity between the anode and cathode composite layers via the LGPS solid electrolyte layer. The material may alternatively include Li3PS4, Li4GeS4, Li2S—SiS2, Li10SnP2S12, and LiVPO4F or other materials not specifically identified.
