Fabrication of LiNi0.8Co0.1Mn0.1O2 cathode materials via Sodium Dodecyl Benzene Sulfonate-assisted hydrothermal Synthesis for Lithium Ion Batteries

The ternary cathode material LiNi 0.8 Co 0.1 Mn 0.1 O 2 for lithium ion batteries was prepared by a novel route by adding sodium dodecyl benzene sulfonate (LAS) which is a surfactant can greatly alleviate the serious agglomeration of particles of the products. The ternary cathode materials were synthesized with metal sulfate as raw materials by the method of hydroxyl co-precipitation. The samples were characterized by XRD, SEM, and electrochemical tests. The mechanism of LAS was analyzed also. The results show that the morphology of acquired particles with 0.42g-LAS was more regular and uniform than that without LAS. The structure of the acquired materials were not affected by adding LAS. The specific capacity of charge and discharge was 240.2 mAh/g, 189.5 mAh/g, and the coulombic efficiency was 78.9% higher than other samples. The specific discharge capacity is 186.3 mAh/g after 50 cycles.
