摘要:
A controlled crystallization method was adopted to synthesize spherical MnCO3, then it was mixed uniformly with Li2CO3 in agate mortar, followed by calcinations at 600 °C and 800 °C for 10 and 24 h respectively, and as a result the spherical or sphere-like spinel LiMn2O4 was formed. The electrochemical performances of LiMn2O4 prepared by normal solid-state reaction and controlled crystallization method respectively were compared. It showed that the stoichiometric spherical LiMn2O4 had obviously excellent electrochemical performance, whose initial reversible capacity was 129.40 mAh/g wi...
