【Abstract】 The method and technology were searched by which Ni and Co was recycled and utilized to synthesize the cathode materials in Li ion cells.The result shows that the charge and discharge performances of synthesized materials are better and the initial charge capacity of the synthesized LiNi 0.3 Co 0.7 O 2 is154.938 mAh/g and approachs that of the cathode material srnthesized with pure Ni and Co precausers.To synthesize Li xNi yCo 1-y O2 as cathode materials in lithium-ion battery with the Ni and Co reclaimed from industry wastewater is practicable and promising.更多还原
