Influence of Ni/Co Ratio for LiCo_xNi_1-xO₂ on Electrochemical Performance

Laboratory on Solid State Ionics, UST Beijing, Beijing 100083, China

摘要: 采用固相反應法合成了一系列LiCo_xNi_1-xO₂（0≤x≤1）材料,用XRD和電化學實驗方法研究了Co³⁺取代Ni³⁺對LiNiO₂材料電化學性能的影響.結果表明,當Ni/Co比例為8:2時材料具有最好電化學性能,比容量可以達到170～180mAh/g,并且具有好的抗過充性能.

Abstract: A series of LiNi_1-xCo_xO₂ (0<x< 1) were synthesized by solid state reaction. The effect of Co³⁺ substitution on Ni³⁺ content was investigated by XRD and electrochemical techniques. It is shown that LiNi_0.8C_0.2O₂ has the best electrochemical performance, delivering specific capacities of 170-180 mAh/g and good over-charge resistance compared with LiNiO₂.
