Nowadays, people mainly the effort and time spent in the study of new carbon materials. As a more common polyaniline conductive polymer material, because it has the raw materials readily available, making simple features, while the stability of its chemical, electrochemical redox reversibility and conductivity, has been to get peoples attention. Polyaniline Quito grade mesoporous carbon materials have the potential to become a super capacitor. People with low cost materials such as methanol, acetic acid and aniline in a small beaker, and the small beaker in 0℃-5℃ ice mixture stirred on the electronic mixer 30min, into the amount of over-ammonium sulfate, stirred for 10h, then filtered, dried and ground to obtain polyaniline powder. With a resistance furnace at different temperatures to obtain polyaniline carbonized polyaniline mesoporous carbon level in Quito, and then again after proper activation and carbonization, washed, filtered and dried to obtain the desired level of polyaniline Quito mesoporous carbon samples. In 6mol/LNaOH aqueou
