1. A method of making an anode for use in an energy storage device, the method comprising:
providing an electrically conductive current collector comprising an electrically conductive layer and a transition metal oxide layer overlaying over the electrically conductive layer; and
depositing a continuous porous lithium storage layer onto the transition metal oxide layer by PECVD, wherein the continuous porous lithium storage layer has a total content of silicon of at least 80 atomic %.
