摘要：

The quaternary spinel LiMn2-xMgxO4 in which a part of Mn is replaced by Mg (x=0 similar to 0.5) are prepared, and Mn valence was determined by chemical analysis. The effect of electrode characteristics of the positive electrode active materials was investigated. The lattice parameter a decreased and Mn valence increased with increasing Mg content. Substitution a part of Mn with Mg brought to a good cycle performance in spite of some decrease on the initial capacity.
