  • Alkaline cell with flat housing and nickel oxyhydroxide cathode
    Patent number: 7435395
    Abstract: An alkaline cell having a flat casing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising nickel oxyhydroxide. The casing can have a relatively small overall thickness, typically between about 5 and 10 mm, but may be larger. Cell contents can be supplied through an open end in the casing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes a vent mechanism, preferably a grooved vent, which can activate, when gas pressure within the cell reaches a threshold level typically between about 250 and 800 psig (1724×103 and 5515×103 pascal gage). The cell can have a supplemental vent mechanism such as a laser welded region on the surface of the casing which may activate at higher pressure levels.

  • Alkaline battery including nickel oxyhydroxide cathode and zinc anode
    Patent number: 7273680
    Abstract: A primary alkaline battery includes a cathode including a nickel oxyhydroxide and an anode including zinc or zinc alloy particles. Performance of the nickel oxyhydroxide alkaline cell is improved by adding zinc fines to the anode.
