Abstract
A rechargeable, thin film lithium battery cell (10) is provided having an aluminum cathode current collector (11) having a transition metal sandwiched between two crystallized cathodes (12). Each cathode has an electrolyte (13) deposited thereon which is overlaid with a lithium anode (14). An anode current collector (16) contacts the anode and substantially encases the cathode collector, cathode, electrolyte and anode. An insulator (18) occupies the spaces between the components and the anode current collector.
