Abstract:
An anode for an energy storage device includes a current collector having a metal layer; and a metal oxide layer provided in a first pattern overlaying the metal layer. The anode further includes a patterned lithium storage structure having a continuous porous lithium storage layer selectively overlaying at least a portion of the first pattern of metal oxide. A method of making an anode for use in an energy storage device includes providing a current collector having a metal layer and a metal oxide layer provided in a first pattern overlaying the metal layer. A continuous porous lithium storage layer is selectively formed by chemical vapor deposition by exposing the current collector to at least one lithium storage material precursor gas.
