What’s more, it also exhibit significantly enhanced cyclability compared to that of 1-Al2O3@LNCM cathodes prepared form the normal solid state method, which further illustrates the efficiency and superiority of this plasma-enhanced method. More importantly, the rate performance of PLA-1-Al2O3@LNCM is improved because of the better electrolyte storage of the assembled hierarchical architecture of the Al2O3 coating layer affording unimpeded Li+ diffusion from electrode to electrolyte. When cycling at 55 °C, the PLA-1-Al2O3@LNCM shows 93.6% capacity retention after 100 cycles, which is greatly enhanced due to the uniform Al2O3 layer. Meanwhile, growth of polarization impedance during cycling can be effectively suppressed by Al2O3 layer, which can further confirm the effect Al2O3 layer coated on the surface of the LNCM. The enhanced cycling performance and thermal stability can illustrate this facile surface modification using the plasma-enhanced method can form effective structure of coating layer, which indicates its great application prospects in the modification on other electrode materials.
