摘要：

采用柠檬酸盐法在不同温度下合成了LiNi1/3Mn1/3Co1/3O2, 并考察了不同合成温度对材料形貌及性质的影响. X射线衍射（XRD）结果表明, 900 ℃烧结的样品具有最完整的晶体结构,  电化学测试结果表明, 该样品具有良好的循环性能与倍率性能, 首次充放电效率达到91.3％. 

关键词: 锂离子电池, 柠檬酸盐法, LiNi1/3Mn1/3Co1/3O2, 电化学性质

Abstract:

LiNi1/3Mn1/3Co1/3O2 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％.

Key words: lithium\, ion batteries, citrate process, LiNi1/3Mn1/3Co1/3O2, electrochemical properties
