The surface-coated cathode material contains a substrate and a coating layer coated on a surface of the substrate, and the coating layer has a bimodal distribution of characteristic peaks at 31°-35° of 2θ tested by X-Ray Diffraction (XRD); and a ratio I/Iof a peak intensity Iof a secondary peak to a peak intensity Iof a primary peak in a bimodal distribution is within a range of 0.8-1, preferably within a range of 0.97-1.",
