  • Electrochemical cell, gelled anode, and coated current collector therefor
    Patent number: 5721068
    Abstract: An electrochemical cell having a negative current collector coated with an alloy of bismuth and tin maintains acceptable performance level and is protected from failure due to vibration. Improved environmental compatibility is achieved by coupling the coated current collector with an anode that contains an alloy powder of bismuth and zinc that is substantially free of mercury, cadmium, calcium, indium, gallium, thallium, lead, and tin. Performance of electrochemical cells can also be improved by providing a soluble bismuth additive in the cell electrolyte.
