An alkaline cell having a flat housing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising MnO2. The housing can have a relatively small overall thickness, typically between about 5 and 10 mm. Cell contents can be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes a vent mechanism which can activate, when gas pressure within the cell reaches a threshold level typically between about 100 and 300 psig (6.89×105 and 20.69×105 pascal gage). The cell can have primary and supplemental vent mechanisms such as welded or thinned regions on the surface of the housing which may activate at different pressure levels. The cathode can be formed of a plurality of stacked slabs having aligned hollow centers with an elongated opening for anode material to be inserted therein.
A primary alkaline cell comprising a negative and a positive terminal, and an outer housing of cuboid shape, said housing having a closed end and opposing open end, said cell further comprising an anode comprising zinc and a cathode comprising MnO2 within said housing, a separator between said anode and cathode, and an end cap assembly sealing the open end of said housing;
A primary alkaline cell comprising a negative and a positive terminal, and an outer housing of cuboid shape, said housing having a closed end and opposing open end, said cell further comprising an anode comprising zinc and a cathode comprising MnO2 within said housing, a separator between said anode and cathode, and an end cap assembly sealing the open end of said housing;
A primary alkaline cell comprising a negative and a positive terminal, and an outer housing of cuboid shape, said housing having a closed end and opposing open end, said cell further comprising an anode comprising zinc and a cathode comprising MnO2 within said housing, a separator between said anode and cathode, and an end cap assembly sealing the open end of said housing;
