Abstract

Uniform and spherical Li(Ni_1/3Co_1/3Mn_1/3)O_(2-δ)F_δ powders were synthesized via NH₃ and F^- coordination hydroxide co-precipitation. The effect of F^- coordination agent on the morphology, structure and electrochemical properties of the Li(Ni_1/3Co_1/3Mn_1/3)O_(2-δ)F_δ were studied. The morphology, size, and distribution of (Ni_1/3Co_1/3Mn_1/3)(OH)_(2-δ)F_δ particle diameter were improved in a shorter reaction time through the addition of F^-. The study suggested that the added F improves the layered characteristics of the lattice and the cyclic performance of Li(Ni_1/3Co_1/3Mn_1/3)O₂ in the voltage range of 2.8-4.6 V. The initial capacity of the Li(Ni_1/3Co_1/3Mn_1/3)O_1.96F_0.04 was 178 mAh g^-1, the maximum capacity was 186 mAh g^-1 and the capacity after 50 cycles was 179 mAh g^-1 in the voltage range of 2.8-4.6 V.
