The thin film battery may comprise a glass or ceramic substrate having a coefficient of thermal expansion ("CTE ") of from about 7 to about 10 ppm / ° K, a continuous metal or metal oxide cathode current having a thickness of less than about 3 micrometers and present on a glass or ceramic substrate A current collector, a layer of a cathode material comprising a lithium transition metal oxide that is a continuous film having a thickness of from about 10 to about 80 micrometers and is present on the cathode current collector, a layer of a cathode material having a thickness of about 0.5 to about 4 micrometers, An existing LiPON electrolyte layer, and an anode current collector having any anode material. A method of manufacturing and using the battery is described. |
