Nanostructure LiMn2O3.9Br0.1 particles were prepared by a room-temperature solidstate coordination method for the first time.The structure and morphology of the asprepared materials were analyzed by X-ray diffractometry (XRD) and Transmission electron microscopy (TEM).The electrochemistry performance of the LiMn2O3.9Br0.1 were investigated by electrochemical method.The results show that the LiMn2O3.9Br0.1 are well-crystallized pure phase and consisted of small and uniformly sized particles,with the diameter of the particles is about 80-100 nm.The samples prepared at different temperature possess similar electrochemistry performance.The initial discharge capacity of LiMn2O3.9Br0.1 prepared at 800℃ was 121 mAh g-1 and its discharge capacity remained 96.2 mAh g-1 after 50 cycles.
