  • Patent number: 6489058
    Abstract: The present invention provides a positive electrode for a rechargeable cell including a two-dimensional electrically conductive substrate supporting a coating comprising nickel hydroxide and a binder, preferably a styrene-ethylene/butylene-styrene triblock copolymer binder. The coating is formed by applying a paste to the two-dimensional substrate surface. The present invention also includes the cell made therefrom. The present invention further provides a method of producing this electrode including the steps of forming the paste and coating the paste onto the two-dimensional substrate. The capacity, midpoint voltage and power delivery of the coated electrode are comparable to or exceed those of traditional sintered and foam positive electrodes.

  • Patent number: 6300002
    Abstract: An electrode having a notch along one edge is provided. The notch prevents unintentional internal shorting between the electrode and internal cell structures having an opposing polarity. In a preferred embodiment, the electrode is used in jellyroll electrochemical cells to avoid contact between the most exterior electrode wrap of the jellyroll and the can. A method of making such an electrode from a continuous strip of electrode material is also provided.
