manganese dioxide (EMD) and LiOH·H2O were used as starting materials. The physiochemical properties of the synthesized samples were investigated by thermogravimetry-differential scanning calorimetry...Performances of lithium manganese oxide prepared by hydrothermal processKONG Long(孔龙)1, 2, LI Yun-jiao(李运姣)1, 2, ZHANG Peng(张鹏)3, HUANG Hai-hua(黄海花)3, YE Wang-qi(叶万奇)1, LI Chun-xia(李春霞)1, 2(1......
) and chemical manganese dioxide (MnO2) served as the raw materials. On preparing Li-doped spinels, raw materials with various nominal Li/Mn ratios (0.45 to 0.70) were mixed and ground carefully, then preheated... samples, and this plateau has a tendency to emerge at higher voltage region with increasing Li/Mn ratio. Key words: lithium manganese oxides; spinel; LiMn2O4; Li2MnO3; cyclic voltammetry
