The cell has an anode consisting of a cpd. of formula: M is a gp. IIa, IIb, IVb, Vb or VIIIb element, Fe, Co, Ni, Sn or Pb. Ye is a gp. Va element. X is S, Se, Te. k is 0 or 1. z is not 3. Cpds. (I) is pref. NbSe4, NiPS3, Fe, PS3 or FePSe3. It is pref. coated on a support made of M, or mixed with conducting powder, e.g. acetylene black, graphite or M. The cathode is pref. a gp. Ia, Ib, IIa, IIb, IIIa or IIIb element, pref. Na, K or Li. The anode may be prepd. by dispensing 85-95 wt.% (I) in 15-5 wt.% PTFE. Graphite or acetylen black of particle size is not >10m is added, then alcohol to form a latex. This is pressed on to a support made of M. |
