Description
技术领域
本发明涉及一种超级电容器用聚丙烯隔膜。
背景技术
超级电容器又称双电层电容器、黄金电容、法拉第电容,是一种新型的储能原件,它兼有物理电容器和电池的特性,能提供比物理电容器更高的能量密度,比电池具有更高的功率密度和更长的循环寿命,并且这种电容器己在工业领域实现产业化和实际应用。超级电容器是利用双电层原理的电容器。当外加电压加到超级电容器的两个极板上时,与普通电容器一样,极板的正电极存储正电荷,负极板存储负电荷,在超级电容器的两极板上电荷产生的电场作用下,在电解液与电极间的界面上形成相反的电荷,以平衡电解液的内电场,这种正电荷与负电荷在两个不同相之间的接触面上,以正负电荷之间极短间隙排列在相反的位置上,这个电荷分布层叫做双电层,因此电容量非常大。当两极板间电势低于电解液的氧化还原电极电位时,电解液界面上电荷不会脱离电解液,超级电容器为正常工作状态(通常为3V以下),如电容器两端电压超过电解液的氧化还原电极电位时,电解液将分解,为非正常状态。由于随着超级电容器放电,正、负极板上的电荷被外电路泄放,电解液的界面上的电荷相应减少。由此可以看出:超级电容器的充放电过程始终是物理过程,没有化学反应。因此性能是稳定的,与利用化学反应的蓄电池是不同的。超级电容器具有以下优点:在很小的体积下达到法拉级的电容量;无须特别的充电电路和控制放电电路;和电池相比过充、过放都不对其寿命构成负面影响;从环保的角度考虑,它是一种绿色能源;超级电容器可焊接,因而不存在像电池接触不牢固等问题。
新产品和新功能的电子整机日新月异、产品的市场寿命越来越短,这对电子元件各个方面要求更高。且由于受世界经济环境的影响,电容器产业面临能源成本、材料成本、劳动力成本、环保成本的全面上涨,而产品销售价格却一再下降,整个行业的经营受到双重压力。所以电子元件产业要变强,必须做到企业创新、行业创新、产品创新,才能跟上电子信息整机发展的需要。从结构上看,超级电容器主要由电极、电解质、隔膜、端板、引线和封装材料组成,其中电极、电解质和隔膜的组成和质量对超级电容器的性能起着决定性的影响,采用何种电极、电解质和隔膜材料将基本决定最终产品的类型与特性。为此,我们从隔膜着手,开发新的高性能的隔膜,提供一种超级电容器用聚丙烯隔膜。
