Document Type and Number:
WIPO Patent Application WO/2011/068685
Kind Code:
A3
Abstract:
Embodiments of the invention contemplate forming an electrochemical device and device components, such as a battery cell or supercapacitor, using thin-film or layer deposition processes and other related methods for forming the same. In one embodiment, a battery bi-layer cell is provided. The battery bi-layer cell comprises an anode structure comprising a conductive collector substrate, a plurality of pockets formed on the conductive collector substrate by conductive microstructures comprising a plurality of columnar projections, and an anodically active powder deposited in and over the plurality of pockets, an insulative separator layer formed over the plurality of pockets, and a cathode structure joined over the insulative separator.
