Abstract

To improve the cycle performance of spinel LiMn₂O₄ as the positive electrode of 4 V lithium secondary batteries, the spinel oxysulfide Li_1.02Mg_0.1Mn_1.9O_3.99S_0.01 is synthesized by a sol-gel method using adipic acid as a chelating agent. The structural and electrochemical properties of the synthesized material are examined. Highly crystallized Li_1.02Mg_0.1Mn_1.9O_3.99S_0.01 is synthesized at 750 °C in an oxygen atmosphere. Both cation and anion doping of spinel lithium manganese oxides are very effective for improving the cycle performance of lithium batteries.
