A novel MC/AQ parasitic composite as cathode material for lithium battery

The mesoporous carbon(MC)/AQ parasitic composite was synthesized by filling 9, 10-anthraquinone into pores of MC with sublimation. The composite was charactered by the methods of TDA/DSC, SEM and N₂ adsorption. The electrochemical performance of the composite was investigated by the methods of galvanostatic discharge/charge and cyclic voltammetry. The results indicated that the specific capacity and cycle life of the composite was increased. The initial discharge specific capacity of the composite(75% AQ contained) arrived at 216 mAh/g, after 50 cycles, the specific capacity maintained 76 mAh/g, which was twice as great as AQ electrode's.
