Abstract
A method of producing a battery (10) having a cathode current collector (18), a cathode (12), an electrolyte (13), an anode (14), and an anode current collector (16) is disclosed. The method commences with a substrate (11) upon which the layers of battery components are built upon. The substrate is then removed, as by sputtering, and replaced with a cathode current collector.
