Abstract: A method of forming a lithium ion battery, a lithium ion battery anode, and a lithium ion battery for a vehicle. The method includes exposing a first surface of a lithium layer to carbon dioxide gas and forming a lithium carbonate layer on the first surface of the lithium layer. The method further includes depositing a fluoropolymer layer on a second surface of the lithium carbonate layer to provide a lithium anode. The battery includes one or more battery cells including the anode for the lithium ion battery. The anode includes a lithium layer including a first surface, and a hybrid coating layer disposed on the first surface, wherein the hybrid coating layer includes a plurality of lithium fluoride domains and a plurality of lithium carbonate domains within a carbonaceous matrix.
