Title: Low voltage thin film batteries

Abstract: A low-voltage, thin film battery and methods for making a low voltage battery. The battery includes a ceramic substrate having a first surface and a second surface. A cathode current collector is disposed adjacent to at least a portion of the first surface of the substrate. The current collector has a titanium layer and a gold layer. A high temperature annealed cathode is disposed adjacent to at least a portion of the gold cathode current collector and an electrolyte layer disposed adjacent to the annealed cathode. An annealed anode is disposed adjacent to at least a portion of the electrolyte, wherein the anode is electrically insulated from the cathode and the cathode current collectors by the electrolyte. An anode current collector is disposed adjacent to at least a portion of the anode.
