30½ð±Ò»¹ÊÇÓеãÉÙ£¬¸ø100¸ö°É¡£ With the rapid advancement of the social economy and the sharp increase of the global population, energy plays an increasingly important role in the development of the economy. As the increasingly shortage of the fossil energy, one of the most important topics throughout the world is exploring new energy. Supercapacitors possess excellent performances such as high power capacity, quick charge-discharge, long cycle life and high energy capacity as storage batteries. As a novel storage device, supercapacitor is a special power source owing to its excellent properties that combine the traditional capacitors and batteries. Compared with the conventional electrochemical power sources, the energy storage of supercapacitors is stem from pseudocapacitance based on redox reactions and the charge transfer between double electric layers. Supercapacitor is a new energy storage device that exhibits performance between capacitors and batteries. The greatest feature of supercapacitors is high capacity which can be up to thousands of Farad. The advantages of supercapacitors are delivering extremely high current, quick charge-discharge rate, high efficiency and long cycle life, etc. while the disadvantage is low energy capacity. As an excellent energy storage device, the recent investigations of supercapacitors are focused on electrode materials, electrolyte and separators, among which more attention are paid on electrodes due to their pivotal role in supercapacitors. Polyaniline (PANI), as a readily available, simple preparative and inexpensive material that possesses excellent properties such as stable electrochemistry, good conductivity and high psedudocapacitance, which drives it to be the hot investigation as electrode material for supercapacitors. |
