Study on Modified Spherical Microcrystalline Graphite as Anode Materials for Li-ion Batteries

To improve the electrochemical performance of spherical microcrystalline graphite(SMCG) as anode material for Li-ion battery,resin was coated on the surface of SMCG by means of liquid impregnation.The result showed that the surface of SMCG became smoother after the coating.The coating improved the cycle efficiency of material,from 81.0% before coating to 92.7% after coating.
