Novel double chromate compositions having the general formula: MM'(CrO4)2, wherein M and M' are silver and bismuth, respectively. Methods of making AgBi (CrO4)2 are characterized by reacting silver dichromate with a bismuth salt to provide equal numbers of silver and bismuth atoms. These double chromate compositions have particular utility in batteries as active positive material. Due to the steadiness of discharge voltage and duration of discharge of batteries employing these double chromate compositions, such batteries are especially adapted for use in clocks and in cardiostimulators or pacemakers.
