The primary battery has a cathode containing an oxide composed of one or more metals and pentavalent bismuth, an anode, a separator placed between the cathode and the anode, and an alkaline electrolyte. The metal is an alkali metal, alkaline earth metal, transition metal and / or main group metal. The separator is ion selective or can substantially prevent the soluble bismuth ionic species from diffusing from the cathode to the anode. |
