METHOD OF PREPARING AN ANODE FOR LITHIUM ION BATTERY AND AN ANODE USING THE SAME

摘要

PURPOSE: Provided are a process for producing the cathode for lithium ion secondary battery and the cathode produced by the same, which have long life, high capacity and excellent voltage evenness by coating mixture mixed precursors of crystalline structure carbon and amorphous carbon on a board and sintering it. CONSTITUTION: The process comprises the steps of: i) coating the mixture containing the precursors of the crystalline structure carbon and the amorphous carbon on the board; ii) curing the coated mixture for 2-8hrs after raising temperature of 100-200deg.C by the rate of 0.2-1deg.C/min.; and then iii) sintering it after raising temperature of 500-900deg.C by the rate of 3-10deg.C/min for 2-5hrs and cooling it by the rate of 3-10deg.C/min up to the room temperature.
