A stuble trivalent manganese compound, manganic phosphate, has been found to have good cathode depolarizer properties in strongly acid electrolytes. Manganic phosphate-carbon cathodes of the type used in this work delivered up to 8.5 amp-min per gram of MnPO/sub 4/. This corresponds to over 80% utilization. When coupled with lead in excess fluoboric acid electrolyte, the wattminute capacity per gram of MnPO/sub 4/ was 8. The electrochemical behavior, and charge retention of the cathodes are described. Manganic phosphate and another less stable depolarizer, barium ferrate, furnish cathodes which can be discharged at 200 ma/in./sup 3/ (16.4 cc) without severe polarlzation. The maximum nonpolarizing currents for the MaPO/sub 4/ are discussed in terms of the surface area of carbon admixed with it to form cathodes. The depolarizing properties of a strongly oxidizing, insoluble organic compound chloranil are reported. (auth)
