Title:
POROUS THREE DIMENSIONAL COPPER, TIN, COPPER-TIN, COPPER-TIN-COBALT, AND COPPER-TIN-COBALT-TITANIUM ELECTRODES FOR BATTERIES AND ULTRA CAPACITORS
Document Type and Number:
WIPO Patent Application WO/2010/090956
Kind Code:
A3
Abstract:
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.
