Abstract
A thin film battery comprises 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 collector and having a thickness of less than about 3 micrometers, the cathode current collector being superjacent to the glass or ceramic substrate, a cathode material layer comprising lithium transition metal oxides that is a continuous film having a thickness of from about 10 to about 80 micrometers, the cathode material layer being superjacent to the cathode current collector, a LiPON electrolyte layer superjacent to the cathode material layer and having a thickness of from about 0.5 to about 4 micrometers, and an anode current collector with an optional anode material. Methods of making and using the batteries are described.
