Abstract
An anode for an energy storage device includes a current collector. The current collector includes: i) an electrically conductive substrate including a first electrically conductive material; ii) a plurality of electrically conductive structures in electrical communication with the electrically conductive substrate, wherein each electrically conductive structure includes a second electrically conductive material; and iii) a metal oxide coating. The metal oxide coating includes one or both of: a) a first metal oxide material in contact with the electrically conductive substrate; or b) a second metal oxide material in contact with the electrically conductive structures; or both (a) and (b). The anode further includes lithium storage coating overlaying the metal oxide coating, the lithium storage layer including a total content of silicon, germanium, or a combination thereof. The electrically conductive structures are at least partially embedded within the lithium storage coating. Methods of making the anode are described.
