Abstract
Abstract A button-type battery includes, a) a conductive first terminal housing member; b) a conductive second terminal housing member; c) an anode, a cathode and an electrolyte between the anode and cathode; the anode, the cathode and the electrolyte being collectively received intermediate the first and second terminal housing members; the first and second terminal housing members forming an enclosed housing which holds and protects the anode, the cathode and the electrolyte; and d) the anode having an operative surface within the enclosed housing which faces the cathode, the operative anode surface having been roughened prior to final assembly of the button-type battery. A method of forming a button-type battery comprising the following includes, a) providing an anode within a first terminal housing member, the anode having an outer exposed surface; b) preferably with the anode within the first terminal housing member, roughening the outer exposed anode surface to increase its surface area from that prior to the toughening; and c) assembling the first terminal housing member with the toughened anode therein with a cathode, electrolyte and second terminal housing member to form an enclosed housing which holds and protects the anode, the cathode and the electrolyte. Alternately, the outer exposed anode surface comprises a passivation barrier film, and the toughening includes penetrating through the outer exposed barrier film and anode surface to roughen such surface to increase its surface area from that prior to the penetrating and to expose anode material therebeneath.
