【Abstract】 The method and technology,which Ni and Co was recycled and utilized to synthesize the cathode materials in Li-ion cells, were researched. The results show that the charge and discharge performances of synthesized materials are better and the initial charge capacity of the synthesized LiNi 0.7 Co 0.3 Ois 154.938 mAh/g and approach that of the cathode material synthesized with pure Ni and Co. It is practicable and promising to synthesize Li xNi yCo 1-x O 2 as cathode material in lithium-ion battery with the Ni and Co reclaimed from industry wastewater .更多还原
