Abstract
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.
