A series of Li(Ni1/3Co1/3Mn1/3)1-xCrxO2(0≤x≤0.1) samples were prepared as anode materials of lithium-ion battery by using oxalate co-precipitation method.The crystal structure and surface morphologies of the products were analyzed by means of X-ray diffraction(XRD)and scanning electron microscopy(SEM) methods.The electrochemical performance of Li(Ni1/3Co1/3Mn1/3)1-xCrxO2 was evaluated by charge/discharge tests.Results show that Li(Ni1/3Co1/3Mn1/3)1-xCrxO2(x=0.01,0.03,0.05,0.07) keeps bedded structure of α-2...
