  • End cap assembly and vent for high power cells
    Patent number: 7579105
    Abstract: And end cap assembly and venting system therein for closing and sealing the open end of a cell housing. The end cap assembly comprises a sealing disk underlying an end cap, and a metal support disk between the end cap and the sealing disk. The metal support disk has a plurality of primary vent apertures and a plurality of secondary vent apertures through its surface. The primary vent apertures are spaced apart along a path located at a greater distance from the central longitudinal axis of the metal support disk than the secondary vent apertures. The insulating sealing disk may have a thinned portion therein forming an rupturable membrane circumventing the central hub of the sealing disk. The insulating sealing disk may have protrusions emanating from its top surface to deflect the membrane during rupture. The venting system releases internal gases rapidly from the cell in the event of an abusive or short circuit discharge.

  • 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.
