  • Patent number: 4579724
    Abstract: A low-temperature synthesis of M.sup.II PS.sub.3 (M preferably Fe, Co or Ni) comprises mixing M.sup.2+ cation with P.sub.2 S.sub.6.sup.4- anion; if insoluble, M.sup.II PS.sub.3 precipitates; otherwise, M.sup.2+ cation can be supplied off an M.sup.2+ -cation-exchange resin through which Na.sub.4 P.sub.2 S.sub.6 solution is trickled. The product is X-ray amorphous, and is brought to a desirable degree of partial order by heating at C. for 3 hours. In this form it can reversibly intercalate lithium and, mixed with binder and graphite, is a cathode for a lithium rechargeable cell.
