Abstract
A process of sputter deposition of both a cathode material and an anode material from a single target source. The process includes the steps of deposition sputtering on a porous substrate from a lithiated metal oxide target source to produce an anode. In addition, deposition sputtering on a porous substrate from the same lithiated metal oxide target source is utilized to produce a cathode. A nanostructured battery may be produced having a metal oxide anode and a lithiated metal oxide cathode, wherein the anode and the cathode are generated from a single target source.
