Abstract

The dependence of the electrochemical characteristics of layered cathode materials LiNi_xMn_yCo_zO₂ (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 Li_1.3Al_0.3Ti_1.7(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.

用 NASICON 结构纳米粒子修饰层状阴极材料 LiNixMnyCozO2 的表面对其电化学特性的影响

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。
