Nickel-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 nickel-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.
