摘要

研究了层状正极材料 LiNixMnyCozO2(0.4 ≤ x ≤ 0.6;y = 0.2,0.3;z = 0.2,0.4)的电化学特性与在其表面涂覆具有 NASICON 结构的锂导电材料 Li1.3Al0.3Ti1.7(PO4)3 纳米粒子保护层的方法的关系。结果表明,表面改性降低了长时间充放电循环过程中的容量衰减(最高达 15%),并提高了快速充放电过程的适用性。

Influence of Surface Modification of Layered Cathode Materials LiNixMnyCozO2 by NASICON Structure Nanoparticles on Their Electrochemical Characteristics

Influence of Surface Modification of Layered Cathode Materials LiNixMnyCozO2 by NASICON Structure Nanoparticles on Their Electrochemical Characteristics

The dependence of the electrochemical characteristics of layered cathode materials LiNixMnyCozO2 (0.4 ≤ x ≤ 0.6; y = 0.2, 0.3; z = 0.2, 0.4) on the method of applying a protective layer of nanoparticles of lithium-conductive material Li1.3Al0.3Ti1.7(PO4)3 with NASICON structure onto their surface has been investigated. It is shown that the surface modification reduces the capacity fading during prolonged charge/discharge cycling (up to 15%) and improves the suitability for fast charge/discharge processes.
