Abstract:
A thin-film battery structure comprising:a. an adhesion layer of cobalt deposited on a non-metallic substrate; b. a current collector layer of platinum deposited over said adhesion layer, wherein during the formation of said adhesion layer and said collector layer, said substrate is kept stationary; c. a cathode layer sputtered over said adhesion layer and current collector layer, which layer is formed of a thin-film solid state material, wherein during formation of said cathode layer said substrate is rocked back and forth so as to create an ovular area within which the cathode has desired characteristics, including nanocrystalline grains and proper crystallographic orientation on the substrate; d. a lithium based solid state electrolyte layer sputtered from over said cathode layer; e. a lithium based metal anode formed over said electrolyte layer by the use of an appropriate shadow mask; f. an anode lead configured to connect said anode layer to external circuitry; g. a cathode lead configured to connect said cathode layer to external circuitry; and h. a package sealing and protecting said structure.
