    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: An electrochemical cell has an anode that includes an alkali metal, a cathode that includes fluorinated carbon, a separator between the anode and the cathode, a non-aqueous electrolyte in electrical contact with the anode and the cathode, and at least one of an electrolyte-insoluble additive in the cathode and a electrolyte-soluble additive comprising an oxygen and a nitrogen having an oxidation level higher than +2. Methods for manufacturing and using such cells are also disclosed. The cells are adapted to be stored for extended periods of time at a wide range of high and low temperatures with maintenance of enhanced rate capability and a reduced initial voltage delay.
