Patent number: 5656395Abstract: A metal current collecting substrate for an air cathode in an electrochemical metal air cell is provided for, wherein the substrate is hardened by one of the steps of sandblasting, shotblasting, plastic deformation of the substrate below the recrystallization temperature range of the metal thereof, and heating the substrate to above the transformation temperature of the metal thereof followed by quenching the substrate below the transformation temperature of the metal thereof. Catalytically active materials, most preferably a mixture of carbon and manganese dioxide, are pressed or otherwise disposed upon the hardened substrate. The substrate is capable of being connected to electrical circuitry. Most preferably, the substrate is a metal screen that has been hardened, roughened and pitted by sandblasting before the catalytically active materials are disposed thereupon, and before the substrate is incorporated into an electrochemical metal air cell.Type: GrantFiled: June 7, 1995Date of Patent: August 12, 1997Inventors: Robert B.

Patent number: 5591541Abstract: This invention pertains to alkaline electrochemical cells, typically to metal-air cells of the button-type. Non-reactive elements of cells of the invention are thinner than corresponding non-reactive elements of prior art cells. Such elements can be made thinner because of improved structures of such elements. The anode can is made from a metal strip structure having a higher steel content. The cathode can has a modified temper, which improves relative stiffness and rigidity while retaining sufficient ductility. The seal disposed between the anode can and the cathode can is made thinner. Structure of the corner of the cathode can between the bottom and the side wall is improved. By so reducing the thicknesses of non-reactive elements of the cell, and thus the volume occupied by such non-reactive elements, the fraction of the cell devoted to holding electrochemically reactive anode material therein is increased, with corresponding increase in the milliampere hour capacity of the cell.Type: GrantFiled: May 5, 1995Date of Patent: January 7, 1997Assignee: Rayovac CorporationInventor: John E.

Patent number: 4687714Abstract: A case for enclosing a metal anode, air cathode, and electrolyte of a metal/air electrochemical cell is prepared by securing a multi-functional metallic cover, which has means for providing ingress of oxygen to the air cathode, to a non-conductive container. The container is capable of expanding to accomodate the growth of anodic material during discharge, while the cover is capable of supporting the air cathode against distortion on discharge and serving as the positive terminal of the cell. Metal/air cells and batteries constructed with such a case are also described.Type: GrantFiled: February 4, 1986Date of Patent: August 18, 1987Assignee: Rayovac CorporationInventors: John E.

Patent number: 4649090Abstract: A seal tab consisting of an acrylic adhesive applied to a biaxially-oriented three-ply synthetic paper of polypropylene is used as a sealing means for metal-air electrochemical cells, and batteries constructed thereof. The seal tabs prevent loss of rate capability and capacity due to interactions with the surrounding environment prior to the placement into service of metal air cells, yet without so isolating the cells such that the initial open circuit voltage is deemed unacceptable by the end user. Additionally, the seal tab, as provided, is easily and cleanly removed, which enhances the cell's consumer appeal.Type: GrantFiled: January 22, 1986Date of Patent: March 10, 1987Assignee: Rayovac CorporationInventors: John E.

Patent number: 3964932Abstract: A plurality of deformations is provided in a metal layer in a battery to avoid wrinkles in that metal layer. The deformations may be situated in that portion of the metal layer which is part of a peripheral sealing system for the battery and/or in that portion of the metal layer inside the peripheral sealing system. The deformations may be oriented along axes which are (a) substantially concentric with the edges of the peripheral sealing system, (b) substantially perpendicular to the edges of the sealing system, or (c) neither (a) nor (b). The metal layer may have a pocket indented therein, the indented pocket being situated inside the peripheral sealing system and over the electrodes of the battery.Type: GrantFiled: August 14, 1975Date of Patent: June 22, 1976Assignee: ESB IncorporatedInventors: John E.
