Abstract
A rechargeable, thin film lithium battery cell (10) is provided having a supporting substrate (11), a cathode current collector (12), a cathode (13), a solid state electrolyte (14), an anode (15) and an anode current collector (17). The battery cell (10) also has a ceramic protective layer (19) which covers the exposed or outwardly facing surfaces of the cathode (13), electrolyte (14), and anode (15) and at least a portion of the cathode and anode current collectors (12) and (17),
Claims14
A thin film lithium battery comprising,
- a supporting substrate;
- a stack of battery components mounted to said supporting substrate, said stack including a cathode, an anode, and an electrolyte positioned between said cathode and said anode;
- and
- a ceramic layer in intimate contact with and covering the outwardly facing surfaces of said stack.
A thin film lithium battery comprising,
- a supporting substrate;
- a cathode;
- an anode;
- an anode current collector;
- an electrolyte positioned between said cathode and said anode;
- and
- a ceramic layer in intimate contact with and extending from said substrate and to a position in intimate contact with and covering the exposed areas of cathode, anode and electrolyte above said substrate and at least a portion of said anode current collector.
A method of manufacturing a lithium battery comprising the steps of:
- (a) providing a supporting substrate;
- (b) depositing a stack of components upon the supporting substrate, the stack of components including a cathode, an anode, and an electrolyte;
- and
- (c) depositing a ceramic layer directly upon the exposed surfaces of the stack of components.
