TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The cell (10) is a primary alkaline cell or wafer cell. It is of rigid structure. The third portion of the current collector is bonded to the electrically insulating member by adhesive material so that a portion of the adhesive material contacts a portion of the sealing metal when the current collect is bonded to the insulating member. The anode current collector consists of the sealing metal. The surface portion of the third portion of the anode current collector is pre-coated with the sealing metal. The anode current collector comprises a film laminate having polymeric film layer(s) and metallic layer(s) comprising the sealing metal. The sealing metal has the property of forming a metal film compound comprising same metal oxide and same metal hydroxide on its surface when exposed to ambient air, in which the metal film compound resists attack by alkaline electrolyte. The metal film compound formed on the surface of the sealing metal is insoluble in alkaline electrolyte. The anode comprises an anode active material undergoing electrochemical reaction when the cell is discharged and the sealing metal has a more negative electrochemical potential than the anode active material so that compounds of the sealing metal present on the surface of the sealing metal are not reduced by the anode active material in the presence of the alkaline electrolyte. It includes an anode active material. The sealing metal has a more negative electrochemical potential than the anode active material so that compounds of the sealing metal present on the surface of the sealing metal are not reduced by the anode active material in the presence of the alkaline electrolyte.
