【Abstract】 Lithium ion battery cathode material LiNi 0.8 Co 0.2 O 2 had been gained by using solid state sintering with Ni 0.8 Co 0.2 (OH) 2 and LiOH·H 2O as raw materials. Orthogonal experimental study to optimizing the influence factors such as reaction temperature and time had been done. The results show that lithium nickel cobalt oxide as cathode material with good structure and excellent property can be obtained by controlling the factors strictly. The first specific discharge capacity of the product is more than 160 mA·h/g, and the loose packed density is over 2.0 g/cm 3.更多还原
