N2 - Nickel-rich layered oxides (Ni ≥60%) are considered as the most promising cathode materials for lithium-ion batteries due to its high energy density and low cost. However, its cycling performance is seriously influenced by the synthesis condition, like the sintering temperature, time and atmosphere. Herein, we investigate different properties of LiNi0.83 Co0.11 Mn0.06 O2 (LNCMO) sintered from 720 to 780 °C, and the cathode calcined at 760 ℃ display the most perfect layered structure and the uniform distribution of primary particles size. Therefore, the LNCMO sintered at 760 ℃ exhibited the best rate capability of 118 mAh·g-1 at 10 C and the highest capacity retention of 95.44 % after 100 cycles at 1 C. Our results indicate that the cycling performance and rate capability of LNCMO are heavily depended on the sintering temperature.
