Controlled crystallization method was put forward to synthesize spherical MnCO3.MnCO3 precursor was mixed uniformly with Li2CO3 in agate mortar,followed by calcination at high temperature,and then spherical or sphere-like spinel LiMn2O4 was attained.

• 采用控制结晶法制备出球形MnCO3前驱体,经预处理后得到多孔隙球形Mn2O3,与Li2CO3研磨混料,高温煅烧合成了结晶完整的球形尖晶石型LiMn2O4。
