Preparation, microstructure and electrochemical performance of nanoparticles LiMn2O3.9Br0.1
LiMn2O3.9Br0.1 nanoparticles were prepared by a room-temperature solid-state coordination method. The structure and morphology of the as-prepared materials were analyzed by X-ray diffractometry and transmission electron microscopy. The results show that the LiMn2O3.9Br0.1 is well-crystallized and consists of monodispersed nanoparticles 80–100 nm in size. Results of electrochemical testing show that the samples prepared at different temperatures have similar electrochemical performance. The initial discharge capacities of LiMn2O3.9Br0.1 prepared at 800 °C and 700 °C are 121 mAh g− 1 and 118.9 mAh g− 1, respectively, higher than for LiMn2O4 prepared using the same method.
