ALL-SOLID-STATE BATTERY COMPRISING LITHIUM ALLOY ANODE

An all-solid-state battery is described, wherein the anode comprises an anode material comprising a product of (i) a lithium (Li) powder, and (ii) a metal selected from aluminum (Al), tin (Sn) or mixture thereof, where the product is a prelithiated metal alloy having a chemical formula of LixMy, wherein Li is lithium, M is the metal, and x and y are integers greater than 0 and where a mass ratio of the lithium to the metal is from 1:4 to 1:20, and where the anode is free of a binder material. In some aspects, the N/P ratio is from 1.00 to 2.00.
