  • Additives for electrochemical cells having zinc anodes
    Patent number: 5401590
    Abstract: The invention relates to a method for inhibiting the occurrence of load voltage instability in zinc anodic alkaline cells. The anode active material contains a gelled slurry of zinc alloy particles, a gelling agent, an aqueous alkaline solution and a mixed surfactant containing an anionic surfactant and a non-ionic surfactant. The gelled anode active material inhibits the occurrence of load voltage instability and simultaneously reduces hydrogen evolution even though the cell contains no added amounts of mercury.
