摘要/Abstract

摘要： 锂离子电池正极材料LiNi_1/3Co_1/3Mn_1/3O₂具有放电比容量大、热稳定性好、成本低、安全性能好等优点,但其倍率性能有待进一步提升。本文采用水热法制备了K⁺掺杂LiNi_1/3Co_1/3Mn_1/3O₂材料LNCM-xK。通过X射线衍射谱、场发射扫描电镜和X射线光电子能谱表征LNCM-xK的形貌和结构,通过电化学工作站和蓝电测试系统测试其电化学性能。结果表明:K⁺掺杂能有效降低阳离子混排程度,改善LiNi_1/3Co_1/3Mn_1/3O₂材料的电化学性能,其中当x=0.125时K⁺掺杂LiNi_1/3Co_1/3Mn_1/3O₂样品(LNCM-0.125K)阳离子混排程度最低;LNCM-0.125K样品电化学性能最佳,0.2 C下50次循环后容量保持率为96.15%;在不同电流密度(0.2 C,0.5 C,1 C,2 C,5 C)下进行倍率性能测试,连续充放电30次后LNCM-0.125K样品容量保持率为97.00%。

Abstract: LiNi_1/3Co_1/3Mn_1/3O₂, a cathode material for Li-ion battery, has the advantages of large discharge specific capacity, good thermal stability, low cost, and good safety performance, but its rate performance needs to be further improved. Therefore, K⁺ doped LiNi_1/3Co_1/3Mn_1/3O₂ materials (LNCM-xK) were prepared by hydrothermal method in this paper.The morphology and structure of LNCM-xK were characterized by X-ray diffraction spectrum, field emission scanning electron microscopy and X-ray photoelectron spectroscopy, and its electrochemical properties were tested by electrochemical workstation and blue electric test system. The results show that K⁺ doping can effectively reduce the cation mixing degreeand effectively improve the electrochemical properties of LiNi_1/3Co_1/3Mn_1/3O₂ materials, among which K⁺ doped LiNi_1/3Co_1/3Mn_1/3O₂ (LNCM-0.125K) of x=0.125 has the lowest cation mixing degree. The LNCM-0.125K sample has the best electrochemical performance. The capacity retention rate is 96.15% after 50 cycles at 0.2 C. The rate performance is carried out at different current density (0.2 C, 0.5 C, 1 C, 2 C, 5 C), and the capacity retention rate is 97.00% after 30 cycles of continuous charge and discharge.

Key words: rate performance, K⁺ doping, LiNi_1/3Co_1/3Mn_1/3O₂, cycle performance, Li-ion battery, cathode material
