Electrochemical Performance of La2O3/Li2O/TiO2 Nano-Particle Coated Cathode Material LiFePO4
Cathode material, LiFePO4 was modified by coating with a thin layer of La2O3/Li2O/TiO2 nanoparticles for improving its performance for lithium ion batteries. The morphology and structure of the modified cathode material were characterized
by powder X-ray diffraction, scanning electron microcopy and AES. The performance of the battery with the modified cathode material, including cycling stability, C-rate discharge was examined. The results show that the battery composed of the coated cathode materials can discharge at a large
current density and show stable cycling performance in the range from 2.5 to 4.0 V. The rate of Li ion diffusion increases in the battery with the La2O3/Li2O/TiO2-coated LiFePO4 as a cathode and the coating layer may acts as a faster ion
conductor (La2/3–x
Li3x
TiO3).
