CARBON ELECTRODE MATERIAL FOR LITHIUM ION SECONDARY BATTERY WITH HIGH CAPACITY AND CYCLE PROPERTY

摘要

The present invention relates to a carbon negative electrode material for a high capacity lithium secondary battery having excellent cycle characteristics, and after the soluble solvent is added to a mixture of a thermoplastic resin and a thermosetting resin and uniformly mixed at a rotational speed of 1,000 to 10,000 rpm, A carbon material for a lithium secondary battery negative electrode material was prepared by stabilizing a polymer prepared by thermal polymerization at a temperature at a temperature of 200 to 300 ° C., carbonizing and pulverizing at a temperature of 600 to 1,000 ° C., and a carbon material and carbon for a manufactured lithium secondary battery negative electrode material. A carbon negative electrode material for a lithium secondary battery is manufactured by mixing nanofibers, and the manufactured carbon negative electrode material for a lithium secondary battery has an effect of producing a carbon anode material for a high capacity lithium secondary battery having excellent cycle characteristics.
