Manufacturing of high capacity prismatic lithium-ion alloy anodes

摘要

High capacity energy storage devices and energy storage device components, and more specifically, to a system and method for fabricating such high capacity energy storage devices and storage device components using processes that form three-dimensional porous structures are provided. In one embodiment, an anode structure for use in a high capacity energy storage device, comprising a conductive collector substrate, a three-dimensional copper-tin-iron porous conductive matrix formed on one or more surfaces of the conductive collector substrate, comprising a plurality of meso-porous structures formed over the conductive current collector, and an anodically active material deposited over the three-dimensional copper-tin-iron porous conductive matrix is provided. In certain embodiments, the three-dimensional copper-tin-iron porous conductive matrix further comprises a plurality of columnar projections formed on the conductive current collector with the plurality of meso-porous structure formed on the plurality of columnar projections.
