Using aqua mesophase pitch(AMP) as the precursor and cationic surfactant CTAB as the structure-directing agent,pitchbased mesoporous carbon spheres were synthesized utilizing sol-gel method.The morphology and structure of products were characterized by using SEM,HRTEM,SAXRD and FT-IR,and then the formation mechanism and electrochemical performance of pitch-based mesoporous carbon spheres were studied.The results showed that CTAB and ionized AMP formed gel spheres via S+Ielectrostatic force,and then pitch-ba...
