LiNi_(1/3)Mn_(1/3)Co_(1/3)O_2 compounds were prepared at different temperatures by means of a citrate process. The effects of different temperatures on the morphology and properties were investigated. XRD results show that the sample sintered at 900 ℃ has a well-crystallized structure, and the electrochemical measurements reveal that this sample also exhibits good cycle and rate functions, with an initial coulomb efficiency of 91.3%.
