• Note (General): LiMnO_2 precursors were synthesized by polymerized complex method, using malic acid and ethylene glycol Crystal phase of LiMnO_2 was affected by the reaction temperature and time of starting solution. Differential thermal analysis and thermogravimetry revealed that a large amount of organic species and water was involved in the LiMnO_2 precursor. The chemical composition of LiMnO_2 precursors was found to be in good agreement with that of the starting solution composition. Single phase LiMnO_2 was obtained by heating at 900-940℃, for 12 h. The first discharge capacity of LiMnO_2 exhibited about 190 mAh/g at 0.1 mA/cm^2, in which 120 mAh/g were associated with the 4 V region and 70 mAh/g with the 3 V region. The discharge capacity decreased to 140 mA/g at 0.5 mA/cm^2. The discharge capacity gradually decreased with increasing the number of cycles up to several cycles, but showed stable cycling performance after 10 cycles.
