LiMn2O4-based materials such as LiMn 2O4 and LiMn1.53Ni0.47O 3.67 were synthesized by both conventional-hydrothermal (CH), microwave-hydrothermal (MH) methods and calcination route. Both reaction temperature and reaction time during MH routes were lower than those of CH routes. LiMn2O4 electrode materials were assembled into lithium-ion battery anodes and their electrochemical performances were studied. The results proved that these LiMn2O4 electrodes can be served as conversion anode materials, and show electrochemical activity during the potential range of 0.01-3.0 V versus Li+/Li. For LiMn 1.53Ni0.47O3.67 materials when used as lithium-ion battery anodes, we found that the introduction of Ni can change their electrochemical reaction and thus improve their electrochemical performances.
