  • Alkaline cell with performance enhancing additives
    Patent number: 7169504
    Abstract: 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.

  • Perforated separator for an electrochemical cell
    Publication number: 20040229116
    Abstract: An electrochemical cell is presented having an improved separator disposed at the interface of the anode and cathode. In particular, the separator includes one or more windings of perforated fabric. A conformal separator coating is applied to the fabric and those portions of the cathode that are radially aligned with the apertures. The conformal separator may be formed from combinations of certain polymers and inorganic crosslinking agents.

  • Conformal separator for an electrochemical cell
    Publication number: 20030044686
    Abstract: An electrochemical cell is presented having an improved separator disposed at the interface of the anode and cathode. In particular, the separator conforms to the contour of the electrode and is thinner than conventional separators made of non-woven fabric. The conformal separator may be formed from combinations of certain polymers and inorganic crosslinking agents.
