Abstract
In this paper, spinel LiMn2−x In x O4 powder were prepared by rheological phase reaction method with the CH3COOLi·2H2O, (CH3CO2)2Mn·4H2O, and In2O3. The structures were characterized by X-ray diffraction and the electrochemical cycling performance were also observed. The results showed that the spinel LiMn2−x In x O4 were pure phase with very excellent performance. As a cathode material for lithium secondary batteries, LiMn1.98In2O4 had a high initial discharge-capacity with 132.42 mAh/g and a good cyclic reversibility with 98.9%. Even after 60 cycles, the discharge capacity still kept 126.29 mAh/g.
