摘      要：LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2(NCM) cathode material containing copper was prepared by co-precipitation *** material was characterized by X-ray photoelectron spectroscopy(XPS) and galvanostatic *** data indicate that surface compositions of the samples containing copper are different from the bare *** on surface of particles was enriched,while nickel and lithium content was *** electrochemical performance of NCM was affected by the change of surface *** performance charged to the cutoff voltage of 4.6 V was improved by introducing copper into the *** effects of copper content on electrochemical behaviors of NCM at 4.5 V were discussed.
