Abstract

LiMn₂O_3.9Br_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 diffractometry and transmission electron microscopy. The results show that the LiMn₂O_3.9Br_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 LiMn₂O_3.9Br_0.1 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.
