Characteristic Improvement of Carbon Coating by Furan Resin on Natural Graphite as Anode for Lithium Ion Batteries
Natural graphite and carbonaceous materials are the most promising materials as the anode for lithium ion batteries. Carbon coating on natural graphite can inhibit the insertion of lithium complex into graphite and reduce its irreversibility. This study verifies that furan resin can be used as a carbon-coating material to enhance the electrochemistry of the charging and discharging cycles. Furan resin changes into amorphous carbon after heat treatment at 1100°C. It is determined that the 40 wt.% furan resin/natural graphite combination material clearly improves the electrochemical properties by electrical cycling tests. The surface properties have been investigated by Raman spectroscopy profiles and the bulk analyzed by X-ray diffraction (XRD) measurements.
