The synthesis of CDMO from LiOH and EMD has been investigated by thermogravimetry and pow- der X-ray diffraction analysis.The results showed that it took place from below 100 to 400℃.When the proportion of Li:Mn in the starting mixture was 3:7,the measured weight loss during this process was 7.40% for heat-treated EMD and 8.33% for non-heat-treated EMD.Based on these data and X-ray diffraction results the obtained product would be 3LiMn204 - MnO2.This material was es- sentially amorphous.It can insert 4.7 Li per 3LiMn_2O_4·MnO_2,leading to a capacity of 170- 200 mAh/g and demonstrated reasonable discharge and recharge cycle performance for both test cells and practical batteries.
