ABSTRACT:
A cathode active material for alkaline electrochemical cells comprising an Ag—Bi-M-containing oxidation product produced by oxidizing with an oxidizing agent an Ag—Bi-M-containing neutralized precipitate obtained by reacting inorganic acid salts of silver, bismuth and, optionally, M (M representing at least one metal selected from the group comprised of manganese, nickel and cobalt) with an alkali hydroxide in an aqueous medium; or comprising an Ag—Bi-M-containing oxidation product obtained by reacting inorganic acid salts of silver, bismuth and, optionally, M with an alkali hydroxide in an aqueous medium and in the presence of an oxidizer.
