Method of making a thin film battery with a metallic lithium anode

摘要

A method of producing a thin film battery (20) is now provided wherein the battery cell commences with a substructure having a cathode current collector (32), a cathode (24), an electrolyte (26) and an anode current collector (34). Upon initial charging lithium from the cathode passes through the electrolyte and alloys with the anode current collector to for a unified anode and anode current collector.
