MANUFACTURING METHOD OF CATHODE COMPLEX MATERIAL FOR LITHIUM BATTERIES AND MANUFACTURING METHOD OF ELECTRODE OF LITHIUM BATTERIES USING THE CATHODE COMPLEX MATERIAL, AND CHARGE AND DISCHARGE METHOD OF THE THE LITHIUM BATTERIES
This disclosure synthesizes an anodic composite material Li(LixNiyCozMnwO2+α) of Li2MnO3 series whose theoretical capacity is a level of about 460 mAh/g, and to produce an electrode of a high capacity using the synthesized anodic composite material. Also provided is a method for charging and discharging the electrode. Here, the method for producing an anodic composite material for a lithium secondary battery includes the steps of: mixing a nickel nitrate solution, a manganese nitrate solution, and a cobalt nitrate solution to produce a starting material solution; and mixing the starting material solution with a complexing agent so as to produce an anodic composite material Li(LixNiyCozMnwO2+α) of Li2MnO3 series by means of coprecipitation.
