Abstract

Co doped lithiated vanadium oxides LiV3-xCoxO8 as promising cathode material for lithium ion batteries are prepared with a hydrothermal process. The crystalline phase are characterised by powder X-ray diffraction and the morphology are observed by scanning electron microscope. The electrochemical properties of synthesized samples are investigated by galvanostatic charge and discharge at a current density of 50 mA g-1. The electrochemical properties were greatly improved via Co doping. Among the doping modified material LiV3-xCoxO8, the most excellent performance can be achieved when x=0.01 and 0.03, which keep a specific discharge capacity of about 146 mAh g-1 even after 40 cycles.
