205 57, 205 82, 205111, 205170
Abstract:
Embodiments described herein generally relate to methods and apparatus for forming an electrode structure used in an energy storage device. More particularly, embodiments described herein relate to methods and apparatus for characterizing nanomaterials used in forming high capacity electrode structures for energy storage devices. In one embodiment a process for forming an electrode structure for an energy storage device is provided. The process comprises depositing a columnar metal structure over a substrate at a first current density by a diffusion limited deposition process, measuring a capacitance of the columnar metal structure to determine a surface area of the columnar metal structure, and depositing three dimensional porous metal structures over the columnar metal structure at a second current density greater than the first current density.

Abstract:
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.
