Abstract

PURPOSE:To improve capacity and storage performance, by constituting anode compound with MnO2 and organic binder to increase packing density of the anode. CONSTITUTION:The anode compound 3 comprises MnO2 and an organic binder such as polytetrafluoroethylene, polyethylene, or polystyrene, and is contained in an anode can 1 with a separator 5 and an electrolyte impregnating material 6. On the anode compound 2 a metal porous sheet 3 of Ni or stainless steel with excellent alkali resistance (sponge metal sheet, net, or expanded metal) is provided. A manganese metal layer 4 is formed by reducing MnO2 of the anode surface with a chemical reducing agent preferably such as hot alkaline aqueous solution, alkaline lower aliphatic alcohol, hydrazine, or formaldehyde.
