Abstract

To meet the increasing demand for lithium-ion batteries, the electrochemical properties of Li-rich layered oxides (LLOs), Li_1.2Mn_0.54Ni_0.13Co_0.13O₂, one of the cathodes with high capacity, are still needed to be improved. Using citric acid as a chelating agent, the LLOs with different particle sizes were prepared by sol-gel method under different calcination temperature and aging times. The samples were characterized by X-ray diffraction and scanning electron microscopy. The results indicate that the particle size grows with the increase of calcination temperature, and firstly increases and then decreases when the aging time is prolonged. When the calcination temperature is 850℃ and ages for 10 days, the material presents the best electrochemical performance, especially rate performance. When the Li_1.2Mn_0.54Ni_0.13Co_0.13O₂ electrode is charged and discharged at 0.1 C between 2.0~4.8 V, the discharge capacity is still 206.7 mAh·g^-1 after 60 cycles and the discharge capability is 125.6 mAh·g^-1 at 2.0 C.
