Abstract

Electrochemical intercalation of P F6- into various carbons was studied for the cathode of an Li-ion rechargeable battery. It was found that the capacity of the electrochemical intercalation of P F6- increases with decreasing (002) plane distance, namely, increasing the crystallinity of graphitic-carbon, and the largest capacity was achieved on the carbon with almost ideal graphitic-carbon structure. By using graphitic carbon with high crystallinity and the stable electrolyte of ethylene carbonate-dimethylene carbonate, a rechargeable battery with high capacity (90 mAhg) and rate property was successfully demonstrated.
