Abstract
A nonaqueous secondary cell having a conventional alkali metal anode and a cathode which contains as the active material a chalcogenide having the nominal atom composition M.sub.x N.sub.1-x S.sub.2 where M is Mn, Fe, Ni or Co, or mixtures threof, N is V or Cr or mixtures thereof, and x is less than or equal to 0.5 when N is V and M is Fe; less than or equal to 0.33 when N is V and M is Ni, Co or Mn; and less than 0.33 when N is Cr.
