Abstract:  The carbon materials prepared by PVDF carbonization at different temperatures have similar BET surface area and pores volume. The content of fluorine in the carbons decreased with the carbonization temperature from 1.46% (atm %) at 600¡ãC to 0.18 %(atm %) at 1000¡ãC. The first cycle specific capacity and the initial coulombic efficiency decreases with the decrease of fluorine content in the samples. The first cycle discharge capacity decreased from 982 mAh/g at 600¡ãC to 752 mAh/g at 1000¡ãC and the initial coulombic efficiency decreased from 31.8% at 600¡ãC to 24% at 1000¡ãC. It is believed that fluorine contained in the carbon materials has a positive effect to improve the electrochemical properties as anode materials for Li-ion batteries. © (2012) Trans Tech Publications.
