Abstract
Abstract A button-type battery includes: a) an anode; b) a cathode positioned adjacent to the anode; c) a separator and electrolyte between the anode and the cathode; d) a conductive first terminal housing member in electrical contact with one of the anode or the cathode, the first terminal housing member having a surrounding periphery and a concave central portion intermediate of its surrounding periphery; e) a conductive second terminal housing member in electrical contact with the other of the anode or the cathode, the second terminal housing member having a surrounding periphery and a concave central portion intermediate of its surrounding periphery which is opposingly concave to the concave central portion of the first terminal housing member; and f) the first and second terminal housing members being insulatingly joined and sealed at their respective peripheries to form an enclosed housing which retains and protects the anode, cathode, separator and electrolyte, with the concave central portions of the first and second terminal housing members projecting inwardly toward one another forming opposing inwardly sprung conductive terminals compressively forcing the anode, separator and cathode together. Methods of production are also disclosed.
