摘要： A Li-ion battery cell is formed from deposited thin-film layers and comprises a high-surface-area 3-D battery structure. The high-surface-area 3-D battery structure includes a fullerene-hybrid material deposited onto a surface of a conductive substrate and a conformal metallic layer deposited onto the fullerene-hybrid material. The fullerene-hybrid material is made up of chains of fullerene “onions” linked by carbon nanotubes to form a high-surface-area layer on the conductive substrate and has a “three-dimensional” surface. The conformal metallic layer acts as the active anode material in the Li-ion battery and also has a high surface area, thereby forming a high-surface-area anode. The Li-ion battery cell also includes an ionic electrolyte-separator layer, an active cathodic material layer, and a metal current collector for the cathode, each of which is deposited as a conformal thin film.

摘要： A method and apparatus are provided for the cost effective formation of a composite material which includes metallized carbon nanotubes and/or nanofibers that can be used to form portions of an energy storage device, such as a lithium ion battery. In one embodiment, carbon nanotubes are formed on a host substrate using a catalytic chemical vapor deposition process. An initiation-adhesion layer is formed over the carbon nanotubes and a metallic layer is then deposited on the initiation-adhesion layer and each layer is formed using a wet deposition process. In one embodiment, portions of the host substrate are used to form an electrochemical storage device that may be integrated with other formed electrochemical storage devices to create an interconnected battery array. The battery array may be formed as a woven sheet, panel, or other flexible structure depending upon the type of host substrate material. In one case, the host substrate material may be a flexible fibrous material that has multiple layers formed thereon to form a fiber battery, such as a lithium ion battery.

摘要： A method and apparatus for forming a reliable and cost efficient battery or electrochemical capacitor electrode structure that has an improved lifetime, lower production costs, and improved process performance are provided. In one embodiment a method for forming a three dimensional porous electrode for a battery or an electrochemical cell is provided. The method comprises depositing a columnar metal layer over a substrate at a first current density by a diffusion limited deposition process and depositing three dimensional metal porous dendritic structures over the columnar metal layer at a second current density greater than the first current density.
