| 随着社会经济的迅速发展和全球人口的急剧增长，能源在经济发展中的地位越来越重要，由于化石类能源的日益短缺，所以当今世界的重要课题之一--开发新能源。超级电容器既具有传统电容器功率密度大、可快速充放电、循环寿命长的特点，又具有蓄电池能量密度高的特点。超级电容器作为一种新型的储能元件，它是一种非常特殊的电源材料，因为它有着介于传统电容器和电池之间的性能，与传统的化学电源相比，它的电能储存主要来源于氧化还原赝电容和双电层的电荷传递。超级电容器是一种性能介于普通电容和蓄电池之间的新型储能器件。超级电容器最大的特点就是电容量大，可达上百至数千法拉，超级电容器的优点在于能瞬间释放出极大的电流、充放电速度快且效率非常高、循环寿命好等；缺点是比能量低。超级电容器作为一种性能卓越的储能装置，近年来对超级电容器的研究重点主要集中在电极材料、电解液和隔膜这三个方面。其中，对超级电容器的性能起着关键性作用的是电极的性质，从而受到更多关注。聚苯胺（polyaniline，PANI）由于具有原料易得、合成简便、成本低廉，并且具有良好的化学稳定性、导电性和高的赝电容储能等特性，使其成为了超级电容器电极材料的研究热点。 |

30金币还是有点少，给100个吧。 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. |
