More Information
Summary:Cobalt-based alloys are provided for use as a positive electrode current collector in a solid cathode, nonaqueous liquid electrolyte, alkali metal anode active electrochemical cell. The cobalt-based alloys are characterized by chemical compatibility with aggressive cell environments, high corrosion resistance and resistance to fluorination and passivation at elevated temperatures, thus improving the longevity and performance of the electrochemical cell. The cell can be of either a primary or a secondary configuration.
