Abstract

The spherical Ni_0.8Co_0.1Mn_0.1(OH)₂ precursor with a particle size of 4-5 μm was successfully prepared by controllable co-precipitation method in this paper. LiNi_0.8Co_0.1Mn_0.1O₂ cathode material was synthesized under different calcination conditions. Scanning electron microscopy, X-ray diffraction and electrochemical performance test showed that the material exhibited enhanced performance under the optimized condition. In the voltage of 2.7-4.3 V and 2.7-4.5 V, the maximum discharge specific capacity is 193.8 mAh•g^-1, 204.8 mAh•g^-1 at 0.2 C and 183.4 mAh•g^-1, 188.6 mAh•g^-1 at 1 C, respectively.
