ABSTRACT:
A method for reducing capacity fading of an LiMn.sub.2 O.sub.4 spinel electrode active material comprising substituting a minor amount of Z for Mn in the LiMn.sub.2 O.sub.4 active material, where Z is a metal element having a +4 (IV) valence state and is characterized by an ability to form tetravalent chlorides. The Z substituted LiMn.sub.2 O.sub.4 active material is further characterized by a lesser rate of capacity loss with cycling as compared to LiMn.sub.2 O.sub.4 active material.
