Abstract of the Disclosure A method for manufacturing a stable divalent silver oxide depolar- iser mix wherein the mix is treated with a mild reducing solution of a reducing agent such as methanol followed by a treatment with a strong reducing solution of a reducing agent such as hydrazine to form a layer of silver on the surface of the depolarizer mix. The depolarizer mix is specially prepared for use in a primary alkaline cell which is discharged at a single voltage plateau, and the preliminary treatment of the mix with the mild reducing solution permits the incorporation of greater amounts of divalent silver oxide in the mix, thereby increasing the electrochemical capacity while still providing a single voltage plateau discharge. The treatment with the mild reducing solution gen- erally requires soaking the mix in a solution containing a reducing agent for up to 10 minutes and may be carried out at either room or elevated temp- erature. The subsequent treatment with a strong reducing solution may also require up to about 10 minutes at either room or elevated temperature, with the purpose to provide a substantially continuous and electrolyte permeable layer of silver on the surface of the depolarizer mix. The depolarizer mix is part- icularly adapted for use in a "button" cell construction, and it may contain from about ? by weight to about 100% by weight of divalent silver oxide and still provide a cell with a single voltage plateau discharge.
