ANODES FOR LITHIUM-BASED ENERGY STORAGE DEVICES, AND METHODS FOR MAKING SAME

An anode for an energy storage device includes a current collector having a metal oxide layer. A continuous porous lithium storage layer overlays the metal oxide layer, and a first supplemental layer overlays the continuous porous lithium storage layer. The first supplemental layer includes silicon nitride, silicon dioxide, or silicon oxynitride. The anode may further include a second supplemental layer overlaying the first supplemental layer. The second supplemental layer has a composition different from the first supplemental layer and may include silicon dioxide, silicon nitride, silicon oxynitride, or a metal compound.
