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.
