ABSTRACT:
An electrochemical cell 10 comprises, in its charged state, an anode 14 comprising, as an active anode substance, (i) a metal halide T(1).sup.m+ X.sub.m.sup.- where T(1) is a metal selected from the group consisting in the first series of transition elements, the second series of transition elements, tungsten, aluminium, silicon, tin and lead, m+ is the valency of the metal T(1), and X is a halogen. The cell also comprises a cathode 18 comprising, as an active cathode substance, a metal halide T(2).sup.n+ X.sub.n.sup.-, where T(2) is a metal selected from the group consisting in the first series of transition elements, the second series of transition elements, tungsten, aluminium, silicon, tin and lead, n+ is the valency of the metal T(2), and X is a halogen. The cell further comprises a liquid electrolyte 22, E, containing halogen ions X.sup.-, when the active anode and cathode substances are T(1).sup.m+ X.sub.m.sup.- and T(2).sup.n+ X.sub.n.sup.- respectively, as well as at least one compatible cation, with the active anode and cathode substances being substantially insoluble in the electrolyte at the operating temperature of the cell, at all states of charge and discharge.
