Thin profile batteries with solid electrolyte

A button-type battery comprising:

• a cathode having a solid electrolyte proximate thereto;
• an anode positioned against the solid electrolyte;
• a conductive first terminal housing member in electrical contact with one of the anode or the cathode, the first terminal housing member having a periphery;
• 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 periphery;
• the first and second terminal housing members forming an enclosed dry battery housing which holds and protects the anode and the cathode, an electrically insulative gasket material being received intermediate the first and second terminal housing member peripheries to provide a fluid-tight seal and to provide electrical insulation between the first and second terminal housing members;
• and
• wherein the cathode is bonded to a conductive substrate which bears against and electrically connects with one of the first or second terminal housing members;
• and
• the anode has a diameter which is smaller than that of the cathode and solid electrolyte.
