The invention provides a cathode for an electrochemical cell, an electrochemical cell including the cathode, and a method of resisting a progressive drop in the capacity of the cathode with repeated charge/discharge cycling thereof. The invention involves doping the electrolyte, which is a sodium aluminium halide molten salt electrolyte containing chloride ions, and/or the active cathode substance, which is a nickel containing substance with a minor proportion of a chalcogen so that the chalcogen is dispersed therein. |
