  • Patent number: 9306206
    Abstract: An alkaline cell comprising a housing having a bottom end and a top end, and an electrode assembly disposed within the housing. The electrode assembly comprises a single first electrode and a single second electrode, a separator therebetween, and an electrolyte. The first electrode comprises a hollow outer body and at least one inner body positioned inside the outer body, the outer body and the at least one inner body being joined together inside the housing to form a single substantially homogeneous structure having an essentially uniform electrode properties. The second electrode comprises an intermediate body at least partially disposed between the outer body and the at least one inner body and electrically isolated from the outer body and the at least one inner body.
    Type: Grant

  • Patent number: 5532085
    Abstract: The invention relates to alkaline cells containing manganese dioxide cathode active material. A substance selected from the group of compounds CaWO.sub.4, MgTiO.sub.3, BaTiO.sub.3, CaTiO.sub.3, ZnMn.sub.2 O.sub.4, and Bi.sub.12 TiO.sub.20 is added to the cathode of conventional alkaline cells typically having an anode comprising zinc and cathode comprising manganese dioxide and an alkaline electrolyte. The additive increases the service life of the cell.
