    摘要: A method is disclosed for preparing cathodes loaded with manganese oxide that are suitable for use in metal-air cells. The manganese oxide is prepared from the reduction of potassium permanganate by sodium formate at a substantially neutral pH level to produce manganese oxide sols. The sols are then mixed with a carbon slurry to produce a colloidal suspension. The suspension is subsequently waterproofed before being filtered, washed, dried, and rolled to produce the active catalyst layer for the cathode during discharge of the cell. The catalyst layer is then laminated with a current collector and air diffusion layer. A separator is then added to provide a carbon-based air cathode loaded with manganese oxide.

    摘要: A sulfonic acid type organic surfactant is incorporated into the gelled anode mixture of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant. Zinc fines may also be incorporated into the anode. The electrolyte included in the anode mixture may have a reduced hydroxide concentration. When a cell is provided whose anode mixture includes the two surfactants and zinc fines alone or in combination with a lowered hydroxide concentration in the electrolyte, discharge leakage is reduced and gel gassing is suppressed relative to that of gels lacking both surfactants. Additionally, cell discharge performance is improved relative to that of cells lacking both the zinc fines and lowered hydroxide concentration.

    摘要: A sulfonic acid type organic surfactant is incorporated into the gelled anode of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant. When the two surfactants are provided in a gelled anode in combination, discharge leakage is reduced and gel gassing is suppressed relative to that of gels lacking both surfactants. Additionally, cell discharge performance is improved relative to that of cells lacking both surfactant additives.
