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

摘要

The present invention is to synthesize Li(Li_xNi_yCo_zMn_wO_2+α) which is a Li_2MnO_3-based positive electrode complex material with an excellent theoretical capacity of approximately 460 mAh/g, and to manufacture a high-capacity electrode using the manufactured positive electrode complex material. In addition, the present invention is to provide a method for charging and discharging the electrode. According to the method for manufacturing the positive elctrode complex material for a lithium secondary battery, Li(Li_xNi_yCo_zMn_wO_2+α), which is the Li_2MnO_3-based positive electrode complex material, can be manufactured via a co-precipitation method by mixing a starting material, which is manufactured by mixing a nickel nitrate solution, a manganese nitrate solution, and a cobalt nitrate solution, with a complexing agent.
