The Li-rich material was synthesized by a co-precipitation method,and covered the material with an olive-like coating.The crystal structure and morphology of the materials before and after coating were observed by X-ray diffractometer and scanning electron microscope,and studied the electrochemical property of the coated lithium-rich material.The results shown that coating had no effect on the crystal structure,and the surface of the material coated with olivine was smooth.In addition,the electrochemical performance test of the material after olivine coating shown that the cycle stability,voltage stability,and impedance test of the material after olivine coating all had improved significantly.
