Effect of Carbon Coating on Electrochemical Performance of Treated Natural Graphite as Lithium‐Ion Battery Anode Material

Carbon‐coated natural graphite has been prepared by thermal vapor decomposition treatment of natural graphite at 1000°C. Natural graphite coated with carbon showed much better electrochemical performance as an anode material in both propylene carbonate‐based and ethylene carbonate‐based electrolytes than “bare” natural graphite. The effect of carbon coating on the electrochemical performance was investigated by solid‐state in conjunction with standard electrochemical techniques. © 2000 The Electrochemical Society.

Effect of carbon coating on the properties of gamma irradiated ultra-high-molecular-weight polyethylene specimens.

We reported the effect of carbon coating on the changes in properties of the ultra-high-molecular-weight polyethylene standard material (Hospital for Special Surgery) alter gamma irradiation in air and storage for 2 years. The coating showed a slight improvement in crystallinity (X-ray) and tensile properties (under cyclic loading) over the uncoated and irradiated control group. The oxidation level as measured by Fourier- transform infrared spectroscopy was unaffected by coating.
