Patent ID: 7531271

Claim:
A wafer alkaline cell comprising a negative and a positive terminal, and a pair of opposing sides comprising at least the majority of the boundary surface of said cell, said opposing sides defining a short cell dimension therebetween, said short dimension being between about 0.5 and 6 mm, said cell comprising an anode assembly and a cathode assembly secured together forming a laminate structure, said anode assembly comprising an anode material and said cathode assembly comprising a cathode material therein, wherein said anode assembly comprises a housing for said anode, and said cathode assembly comprises a housing for said cathode, said anode and cathode assemblies being adhesively bonded together with a separator there-between to form a laminate structure, wherein said anode housing comprises an anode frame having an inner peripheral edge defining the boundary of an anode cavity, an outer peripheral edge defining the outer boundary of the anode frame, said frame having a front side and opposing back side comprising said peripheral edges; said anode housing further comprising an anode current collector sheet bonded by adhesive material to the back side of said anode frame so that said anode current collector sheet faces an outer surface boundary of the cell, and wherein the anode material is disposed in said anode cavity so that it is in contact with said anode current collector sheet, wherein at least a portion of said anode current collector sheet is precoated with a sealing metal or comprises a sealing metal so that at least a portion of said adhesive material contacts at least a portion of said sealing metal when said anode current collector sheet is bonded to said anode frame.
