Abstract
A method of making an anode for use in an energy storage device is provided. The method includes providing a current collector having an electrically conductive substrate and a surface layer overlaying a first side of the electrically conductive substrate. A second side of the electrically conductive substrate includes a filament growth catalyst, wherein the second side is opposite the first. The method further includes depositing a lithium storage layer onto the surface layer using a first CVD process forming a plurality of lithium storage filamentary structures on the second side of the electrically conductive substrate using second CVD process.
