| 隨著社會經(jīng)濟的迅速發(fā)展和全球人口的急劇增長，能源在經(jīng)濟發(fā)展中的地位越來越重要，由于化石類能源的日益短缺，所以當今世界的重要課題之一--開發(fā)新能源。超級電容器既具有傳統(tǒng)電容器功率密度大、可快速充放電、循環(huán)壽命長的特點，又具有蓄電池能量密度高的特點。超級電容器作為一種新型的儲能元件，它是一種非常特殊的電源材料，因為它有著介于傳統(tǒng)電容器和電池之間的性能，與傳統(tǒng)的化學電源相比，它的電能儲存主要來源于氧化還原贗電容和雙電層的電荷傳遞。超級電容器是一種性能介于普通電容和蓄電池之間的新型儲能器件。超級電容器最大的特點就是電容量大，可達上百至數(shù)千法拉，超級電容器的優(yōu)點在于能瞬間釋放出極大的電流、充放電速度快且效率非常高、循環(huán)壽命好等；缺點是比能量低。超級電容器作為一種性能卓越的儲能裝置，近年來對超級電容器的研究重點主要集中在電極材料、電解液和隔膜這三個方面。其中，對超級電容器的性能起著關鍵性作用的是電極的性質(zhì)，從而受到更多關注。聚苯胺（polyaniline，PANI）由于具有原料易得、合成簡便、成本低廉，并且具有良好的化學穩(wěn)定性、導電性和高的贗電容儲能等特性，使其成為了超級電容器電極材料的研究熱點。 |

30金幣還是有點少，給100個吧。 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. |
