Abstract
A rechargeable, thin film lithium battery cell (10) is provided having a polyimide supporting substrate (11), a cathode current collector (13), a lithiated transition metal oxide or transition metal cathode (14), an electrolyte (15), an anode (16) and an anode current collector (17). The polyimide supporting substrate (11) is heated or dehydrated to remove water from therein. The cathode (14) is annealed at a relatively low temperature of approximately 300 degrees Celsius.
