| Abstract: | The aim of this investigation is to determine optimised spinel cathode compositions that can be used in lithium cells. The cycling stability of 4 V LixMn2O4 electrodes in lithium, flooded electrolyte glass cells has been improved by the addition of multivalent cation dopants (Mg2+,Zn2+ and Al3+). Optimal dopant levels to achieve maximum capacity and the greatest stability with repeated cycling have been determined. The effect of doping the oxygen-rich-spinel Li2Mn4O9 was also determined and shown to make no significant improvement in the life cycle stability in the 3 V region. |
