Abstract： |
The invention relates to an anode material doped with tin of lithium manganese oxide, and relative preparation. Wherein, the mechanical formula of material is Li (MnxSnz) 2O4; x and z are the mol ratios of manganese and tin while x+z=1; the tin mol is 0.1-10% of total mol of tin and manganese. And the preparation comprises: mixing the compound which can generate manganese metal oxide or the oxide which can generate manganese in high temperature, the compound which can generate tin oxide at high temperature, and the compound which can generate lithium oxide at high temperature or lithium oxide, to solidify at high temperature, to obtain the lithium manganese oxide anode material doped with tin, while the reaction temperature is 600-1000Deg. C, the temperature kept time is 5-40 hours. The inventive method has low cost and simple process. |
