Cathode material for alkali-metal rechargeable cell

Brian Anthony Nevett (Inventor)
, Peter Foot (Inventor)

Research output: Patent

Abstract

A low-temperature synthesis of M<II>PS3 (M preferably Fe, Co or Ni) comprises mixing M<2+> cation with P2S6<4-> anion; if insoluble, M<II>PS3 precipitates; otherwise, M<2+> cation can be supplied off an M<2+>- cation-exchange resin through which Na4P2S6 solution is trickled. The product is X-ray amorphous, and is brought to a desirable degree of partial order by heating at 350<o>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.
