Fluorine-doped anatase TiO2 (FATO) is successfully coated with thickness of 4-6 nm on the surface of Li1.2Mn0.54Ni0.13Co0.13O2 particles to improve the electrochemical and thermal properties of the Li-rich cathode via a wet chemical method. The cathode coated by 2 wt% of FATO shows excellent electrochemical performances and high thermal stability. This sample delivers discharge capacities of 300.1 mAh g(-1) at 1 C and 257 mAh g(-1) even at 10 C. Besides, it shows high capacity retentions of 91.5% and 73.2% after 500 cycles at 1 C and 5 C, respectively. Furthermore, in-situ XRD patterns confirm that the coated sample delivers the decomposition temperature of 293 degrees C to convert hexagonal structure (R-3m) to cubic spinel structure (Fd-3m). This study shows that the nanoscale coating layer containing oxygen vacancies can greatly enhance electrochemical and thermal properties of Li-rich cathode materials used in high performance lithium ion batteries.
