Abstract:

A mesoporous carbon material formed on an electrode surface in an energy storage device, and a method of forming the same are disclosed. The mesoporous carbon material acts as a high surface area ion intercalation medium for the energy storage device, and is made up of CVD-deposited carbon fullerene “onions” and carbon nanotubes (CNTs) that are interconnected in a fullerene/CNT hybrid matrix. The fullerene/CNT hybrid matrix is a high porosity material that is capable of retaining lithium ions in concentrations useful for storing significant quantities of electrical energy. The method, according to one embodiment, includes vaporizing a high molecular weight hydrocarbon precursor and directing the vapor onto a conductive substrate to form a mesoporous carbon material thereon.

Abstract:

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.
