Laminated Lithium Metal Anode With Protective Coatings

Abstract:

An anode for a lithium metal battery includes a current collector, a LiPON layer on the current collector, a solid polymer layer on the LiPON layer and a porous separator laminated to the solid polymer layer. The solid polymer layer can be a linear polymer mixed with an ion conducting filler. The solid polymer layer can be a polymer matrix formed from a solidified polymer network comprising a crosslinked polymer mixed with an ion conducting filler.
