ABSTRACT:
An electrochemical cell comprises as an anode, a lithium transition metal oxide or sulphide compound which has a [B2]X4n−spinel-type framework structure of an A[B2]X4spinel wherein A and B are metal cations selected from Li, Ti, V, Mn, Fe and Co, X is oxygen or sulphur, and n− refers to the overall charge of the structural unit [B2]X4of the framework structure. The transition metal cation in the fully discharged state has a mean oxidation state greater than +3 for Ti, +3 for V, +3,5 for Mn, +2 for Fe and +2 for Co. The cell includes as a cathode, a lithium metal oxide or sulphide compound. An electrically insulative lithium containing liquid or polymeric electronically conductive electrolyte is provided between the anode and the cathode.
