In a cell is of the high temperature alkali metal/transition metal halide type, having a molten sodium anode (68), a nickel/nickel chloride cathode, an essentially sodium aluminium chloride molten salt electrolyte and a solid electrolyte sodium ion conducting separator (14) which separates the sodium from the molten salt electrolyte, the nickel/nickel chloride is dispersed in solid form in a porous electronically conductive electrolyte-permeable matrix (66) which is impregnated by the molten salt electrolyte, and antimony in finely divided solid form is mixed with the nickel/nickel chloride in the matrix, the mass ratio of antimony to the nickel in the nickel chloride in the cell in ill fully charged state being 2:100 - 130:100. The antimony can be dispersed in the active cathode material before the active cathode material is dispersed in the matrix and the cathode activated by charging in a cell at sufficiently low voltage to avoid any chlorination of the antimony. <IMAGE> |
