Patent Images
1. A thin film lithium battery comprisingan aluminum cathode current collector having a transition metal coating, wherein the transition metal is selected from the group consisting of vanadium, manganese, magnesium, iron, germanium, chromium, nickel and zinc;
- a crystallized lithium intercalation compound cathode deposited upon said coated aluminum cathode current collector;
an anode;
an electrolyte disposed between said lithium intercalation compound cathode and said anode; and
an anode current collector coupled to said anode.

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.
