This study retrieved from spent lithium nickel cobalt batteries, lithium battery cathode material made again. The battery assembly and battery charge and discharge tests. So can waste resources and reduce environmental pollution and reduce the battery cell manufacturing costs. Currently lithium battery recycling waste processing method is the use of hydrometallurgy, the lithium, cobalt, nickel, manganese and other elements separate one by one. Were made from a variety of pure oxides or carbonates, complicated process, economic efficiency as expected. The study will capture waste batteries cobalt, lithium, nickel, made of lithium nickel proportion of the process solution of lithium, nickel, manganese, cobalt, add the lack of metalion ingredients. After adjusting the correct composition of cathode electrode material powder sintering. Thus eliminating the need for separate elements of procedures and the cost can be greatly reduced. Reproduction of the cathode material. That SEM and XRD is observation of the fine structure and organization and finally assembled into a battery. The battery charge and discharge performance test can reach 122.21 mAh / g and 85% is about the pure raw materials production. So it can reduce the manufacturing cost of the cathode material. The waste of valuable battery cobalt and other materials to be recycled to reduce waste and resource the head.
