Alkaline cell with silicate ion containing - electrolyte

The cell has a positive electrode, pref. of silver oxide, a negative electrode of zinc negative active material and a separator between them. The alkaline electrolyte is contained within the separator and electrodes without establishing a liquid level of free electrolyte in the cell. After wetting the components, silicate ions are present in the electrolyte in an amount between 0.05 wt.% and a maximum such that the capacity of the silicate-ion-containing cell is greater than that of an identical cell without the silicate ions.
