Abstract

Vanadium-sol modified LiFePO4 material was prepared by 300 °C calcination in a tube furnace. The modified LiFePO4 material was characterized by X-ray diffraction, field emission scanning electron microscopy, energy disperse spectroscopy and electrochemical impedance spectroscopy. The results indicated that vanadium-sol modified LiFePO4 had higher first cycling efficiency, lower impedance and polarization, and better electrochemical properties at high charge/discharge rates.
