| 摘要 |
A method for forming a battery from via thin-film deposition processes is disclosed. A mesoporous carbon material is deposited onto a surface of a conductive substrate that has high surface area, conductive micro-structures formed thereon. A porous, dielectric separator layer is then deposited on the layer of mesoporous carbon material to form a half cell of an energy storage device. The mesoporous carbon material is made up of CVD-deposited carbon fullerene "onions" and carbon nano-tubes, and has a high porosity capable of retaining lithium ions in concentrations useful for storing significant quantities of electrical energy. Embodiments of the invention further provide for the formation of an electrode having a high surface area conductive region that is useful in a battery structure. In one configuration the electrode has a high surface area conductive region comprising a porous dendritic structure that can be formed by electroplating, physical vapor deposition, chemical vapor deposition, thermal spraying, and/or electroless plating techniques.
