Abstract: An anode for an energy storage device includes a current collector having an electrically conductive layer and a surface layer disposed over the electrically conductive layer. The surface layer may include a first surface sublayer proximate the electrically conductive layer and a second surface sublayer disposed over the first surface sublayer. The first surface sublayer may include zinc. The second surface sublayer may include a metal-oxygen compound, wherein the metal-oxygen compound includes a transition metal other than zinc. The current collector may be characterized by a surface roughness Ra ? 250 nm. The anode further includes a continuous porous lithium storage layer overlaying the surface layer. The continuous porous lithium storage layer may have an average thickness of at least 7 µm, may include at least 40 atomic % silicon, germanium, or a combination thereof, and may be substantially free of carbon-based binders.

Abstract: A method of making an anode for use in an energy storage device includes providing a current collector having an electrically conductive layer and a metal oxide layer overlaying over the electrically conductive layer. The metal oxide layer has an average thickness of at least 0.01 ?m. A continuous porous lithium storage layer is deposited onto the metal oxide layer by a CVD process. The anode is thermally treated after deposition of the continuous porous lithium storage layer is complete and prior to battery assembly. The thermal treatment includes heating the anode to a temperature in a range of 100° C. to 600° C. for a time period in a range of 0.1 min to 120 min. The anode may be incorporated into a lithium ion battery along with a cathode. The cathode may include sulfur or selenium and the anode may be prelithiated.
