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/&#xb0; 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.

Thin film batteries comprising a glass or ceramic substrate

A first current collector on the first surface of the substrate and a second current collector having a first surface and a perimeter. One of the first and second current collector is an anode current collector and the other is a cathode current collector. The battery also comprises a cathode material having a perimeter, the cathode material being located on the cathode current collector; an electrolyte layer having a perimeter, the electrolyte separating the cathode material from the anode current collector; an insulation layer having a perimeter, the insulation layer together with the electrolyte layer separating the anode current collector from the cathode material and the cathode current collector. A first passivation layer generally overlies at least the perimeter of the cathode material, the perimeter of the electrolyte, and the perimeter of the insulation layer, the first passivation layer being electrically coupled to the first current collector and forming a continuous metal to metal seal around a defined area of the first current collector. The first passivation layer has a via opening. A second passivation layer is electrically coupled to the second current collector through the via opening of the first passivation layer.

A battery-operated device provided on a thin-film battery and a method for making. Some embodiments provide a system that includes a vacuum chamber, a plurality of pairs of source and take-up reels within the vacuum chamber, including a first source reel that supplies a first strip of substrate material and a first take-up reel, and a second source reel that supplies a first mask strip having a plurality of different masks and a second take-up reel, a first deposition station configured to deposit material onto the first strip of substrate running between the first source reel and the first take-up reel, as defined by the first mask strip running between the second source reel and the second take-up reel, and a controller operatively coupled to run the first strip of substrate between the first source reel and the first take-up reel at a first independent rate and tension, and to run the mask strip between the second source reel and the second take-up reel.
