ABSTRACT:
The invention provides an electrochemical cell, a cathode therefor and methods of making them. The cell is of the high temperature alkali metal/transition metal halide type, having a molten sodium anode, a nickel
ickel chloride cathode, an essentially sodium aluminium chloride molten salt electrolyte and a solid electrolyte sodium ion conducting separator which separates the sodium from the molten salt electrolyte. The nickel
ickel chloride is dispersed in solid form in a porous electronically conductive electrolyte-permeable matrix which is impregnated by the molten salt electrolyte, and antimony in finely divided solid form is mixed with the nickel
ickel chloride in the matrix. The mass ratio of antimony to the nickel in the nickel chloride in the cell in its fully charged state is 2:100-130:100.
