| Abstract: | The cathode material LiNi 0.8 Co 0.2 O 2 for lithium ion batteries were synthesized by solid state reaction at high temperature. In such synthesizing process, the effect of raw materials, atmosphere, temperature, time, stochiometry ratio of Lithium to Nickle and Cobalt, Oxygen flux, and the art of the second sintering on this material's crystal structures and electrochemical characteristics were studied. Through optimizing the parameters, the cathode material with specific capacity of 170 mAh/g was synthesized and the electric performance of lithium ion battery using this material as cathode was tested. |
