Abstract
Abstract A method of forming a button-type battery includes: a) providing a sheet of cathode material bonded to solid electrolyte material; b) cutting the cathode material and solid electrolyte material from the sheet into a plurality of composite cathode/solid electrolyte pieces which are individually sized and shaped to constitute the electrolyte and cathode components of a single button-type battery; c) providing a pair of first and second terminal housing members in facing juxtaposition to one another, the first and second terminal housing members having respective peripheries; d) providing one of the composite cathode/electrolyte pieces intermediate the juxtaposed first and second terminal housing members; e) providing an anode intermediate the juxtaposed first and second terminal housing members, the anode being positioned to electrically connect with one of the first or second terminal housing members and the solid electrolyte, and the cathode being positioned to electrically connect with the other of the first or second terminal housing members; f) providing electrically insulative sealing gasket material intermediate the first and second terminal housing member peripheries; and g) crimping the first and second terminal housing member peripheries together into an enclosed dry battery housing with the gasket material being interposed between the first and second terminal housing members to provide a fluid-tight seal and to provide electrical insulation therebetween. A button-type battery is also disclosed.
