Abstract:
In this paper, LiOH·H 2 O and Li 2 CO 3 , which were widely used in industry and (Mn 0.533 Co 0.233 Ni 0.233 ) (OH) 2 prepared by ourselves selected as starting materials, series materials of lithium-rich layered material Li [Li 0.2 Mn 0.44 Ni 0.18 Co 0.18 ]O 2 were obtained by a molten salt method. Their structures and properties of the materials were investigated by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and constant current charge/discharge methods. The effects of different LiOH and Li 2 CO 3 molar ratios on the Li [Li 0.2 Mn 0.44 Ni 0.18 Co 0.18 ]O 2 structures and properties were characterized. The results of the experiments indicate that The structures of the material such as crystal structure, the specific area, particle size distribution, tap densities were controlled by adjusting the proportion of the two lithium sources. Forthermore , when the molar ratio of LiOH and Li 2 CO 3 was 3:7, the maximum discharge capacity (214.77 mAhg -1 ) of the cathode was obtained.
