摘要
Abstract
The spinel LiMn2O4 is one of the most bright and competitive cathode material used in HEV, PHEV and EV for its lower price, environment friendly and good safety etc. However, at present, the poor thermo stability and cycling life is the main problem, which prevents the wide application of LiMn2O4 in power battery. In this study, the various manganese precursors were used to synthesize spinel LiMn2O4, It is found that the cycling performance of LiMn2O4 made from Mn3O4 is much more excellent than others. The capacity retention of LiMn2O4 made from Mn3O4 achieves 91.2% after 480 cycles with 1 C charge and discharge rate at room temperature and 89.7% after 300 cycles with 1 C charge and discharge rate at 45 ℃.关键词
