Preparation, microstructure and electrochemical performance of nanoparticles LiMn2O3.9Br0.1

Journal Article


Abstract


  • "LiMn(2)O(3.9)Br(0.1) 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 diffractometty and transmission electron microscopy. The results show that the LiMn(2)O(3.9)Br(0.1) 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 LiMn(2)O(3.9)Br(0.1) prepared at 800 degrees C and 700 degrees C are 121 mAh g(-1) and 118.9 mAh g(-1), respectively, higher than for LiMn(2)O(4) prepared using the same method.
