Abstract

Fine-sized LiMn2O4 powders were prepared by solid-state reaction method using the nano-sized manganese oxide powders. Nano-sized manganese oxide powders obtained by spray pyrolysis from spray solution with citric acid and ethylene glycol formed the fine-sized LiMn 2O4 powders with regular morphology by solid-state reaction method with LiOH. The mean sizes of the LiMn2O4 powders prepared from the nano-sized manganese oxide increased with increasing the post-treatment temperatures. Nano-sized LiMn2O4 powders with regular morphology were obtained at low post-treatment temperatures below 800°C. The LiMn2O4 powders post-treated at 800°C had the mean size of several hundreds nanometer and the narrow size distribution. The initial discharge capacity of the fine-sized LiMn 2O4 powders prepared by solid-state reaction method using nano-sized Mn2O3 powders was 127 mAh/g. The discharge capacities of the LiMn2O4 powders dropped from 127 to 112 mAh/g by the 50th cycle at a current density of 0.1 C.
