Abstract
Nature graphite, as anode in rechargeable lithium ion battery, has been attracting widely attention. In this paper, aiming to the disadvantage effect of volume and surface active group on the electrochemical performance of nature graphite anode, graphite intercalation compound and expanded graphite were prepared via bromination and calcination to obtain advanced high rate performance and cycle life. The structural characteristics of samples were measured by XRD (X-ray diffraction), SEM (scanning electron microscope) and BET (Brunauer, Emmett and Taylor) techniques. The results show separation of graphitic layers and a larger diameter size of graphitic grain. Constant current charging-discharging and cyclic voltammetry were carried out, indicating the improved high rate performance and cyclic stability of the modified graphite.
