Effects of surface modification on the cycling stability of LiNi0.8Co0.2O2 electrodes by CeO2 coating

A high-performance LiNi0.8Co0.2O2 cathode was successfully fabricated by a solgel coating of CeO2 to the surface of the LiNi0.8Co0.2O2 powder and subsequent heat treatment at 700 DGC for 5 h. The surface-modified and pristine LiNi0.8Co0.2O2 powders were characterized by X-ray diffraction (XRD), scan...
