To address the shortcomings,such as low tap density and low first cycle Coulombic efficiency of microcrystalline graphite when used as lithium ion battery anode,the paper investigated the liquid phase coating for microcrystalline graphite using vacuum impregnation method.The microscopic structure of the coated sample was tested with XRD,Raman spectrum.The surface feature was characterized by SEM and nitrogen adsorption-desorption.The performance of the sample was determined by galvanostatic test and CV test...
