Abstract: Disclosed is a method of fabricating a battery or battery component having a solid state electrolyte. A scaffold is provided, the scaffold comprising: a dense central layer comprising a dense electrolyte material, the dense central layer having a first surface, and a second surface opposite the first surface; a first porous layer comprising a first porous electrolyte material, the first porous layer disposed on the first surface of the dense central layer, the porous electrolyte material having a first network of pores therein; wherein each of the dense electrolyte material and the first porous electrolyte material are independently selected from garnet materials. Carbon is infiltrated into the first porous layer. Sulfur is also infiltrated into the first porous layer. The battery component may be used in a variety of battery configurations.

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.
