Abstract
Disclosed are electrochemical devices, such as lithium battery electrodes, lithium ion conducting solid-state electrolytes, and solid-state lithium metal batteries including these electrodes and solid-state electrolytes. In one disclosed method, a solid state electrolyte material including a precursor layer having a first electronic conductivity is provided; and the precursor layer on the solid state electrolyte material is reduced to an interfacial layer having a second electronic conductivity greater than the first electronic conductivity. Also disclosed is a method of forming a solid state electrolyte for an electrochemical device including an anode comprising an electrochemically active metal, wherein the method comprises providing a solid state electrolyte material, and depositing an interfacial layer comprising a first metal on the surface of the solid state electrolyte material, wherein the electrochemically active metal does not form an alloy with the first metal during cycling or formation of the electrochemical device.
