Li[Ni1/3CO1/3Mn1/3]O2合成工艺对其结构和性能的影响OA北大核心CSCDCSTPCD
Influence of Synthetic Conditions on Structure and Electrochemical Performance of Li [ Ni1/3Co1/3Mn1/3 ] O2
采用碳酸盐共沉淀法制备Li[Ni1/3Co1/3Mn1/3] O2.研究了前驱体合成温度、时间和焙烧温度、焙烧时间对材料结构和电化学性能的影响.测试结果表明,合成温度为40℃,时间30 h所得前驱体的振实密度和电化学性能较好.XRD测试结果表明,不同焙烧温度下得到的Li[ Ni1/3Co1/3 Mn1/3] O2均具有α-NaFeO2型层状结构.其中800℃下焙烧15 h得到的样品具有较好的层状结构和较低的阳离子混排程度.样品在2.8~4.3V电…查看全部>>
Li[Ni1/3Co1/3Mn1/3]O2 powder was prepared by carbonate co-precipitation method. The effects of the synthesis temperature, synthesis lime, calcination temperature and calcination time on the morphology,structure and electrochemical properties of the cathode material were investigated in detail. The results indicated that the [ Ni1/3 Co1/3 Mn1/3 ] CO, prepared at 40 ℃ for 30 h had the highest tap density and the best electrochemical performance. X-ray di…查看全部>>
