A split type super storage capacitor includes two independent and non-direct contact electrode batteries. The electrode batteries include an insulating shell, an electrode arranged in the insulating shell, a dielectric filled in the gap between the electrodes, a through hole is opened opposite to each other on the insulating shell of the two electrode batteries, and an insulating medium is arranged in the through hole. The two insulating dielectric layers are connected through a conductor, a fuse and a switch. The beneficial effects are as follows: the electric field of split supercapacitor is the strongest at the junction of positive and negative electrode batteries. When the insulating dielectric layer can not bear the potential difference between positive and negative electrode batteries, the current first passes through the fuse, which is fused by the current. The breakdown phenomenon ends instantaneously and the energy release is very little, and the breakdown phenomenon occurs outside the positive and negative electrode batteries. Section, far away from the material in the electrode battery, so as to ensure the overall safety of the battery. By installing an insulating dielectric layer on the insulating shell, the area of the insulating dielectric layer between the positive and negative poles is greatly reduced and the leakage current is reduced.

技术介绍
超级蓄电容器是介于传统电容器和充电电池之间的一种新型储能装置,它既具有电容器快速充放电的特性,同时又具有电池的大容量储能特性。CN107331527A公开了一种超大容量超级电容器,其依据高斯和法拉第电学原理,由三维立体电极和电介质混合构成正负电极池,充电时,电荷在三维立体结构内均匀分布,排布在三维电极表面处,电荷电势处处相等。电介质不导电性质阻止电极内电荷流出到电极池内,设置在正负电极池中间的隔膜阻止正负极间电荷流动。当超级蓄电容器内电介质和隔膜材料介电强度相同时,电容器的电容量公式为C=ε×ε0×S/d,式中:ε-----电极池中电介质介电常数,ε0-----真空介电常数,S-----极板面积=单侧电极池内多孔电极与电介质接触总表面积,d-----隔膜厚度;超级蓄电容器最大储电能计算公式E=1/2CU2,U为隔膜临界击穿电压。根据电容基本原理,平板电容极板上储存电荷密度最大值是恒定值。平板电容储存电能时,用同一种电介质制成隔膜厚度不同(额定击穿电压不同)的平板电容,充以临界击穿电压时,额定电压1伏和1万伏的电容器电极板上的最大电荷密度相同,即平板电容电极板上的最大电荷密度是一个恒定值。平板电容如果要增大储存电能量,只有通过增大极板面积(增加储存电荷数量)或介质厚度(增大电荷电势能)两种方法,随之带来电容体积和质量的线性增加,因此平板电容能量密度很小。该文献是利用正负电极池内三维立体极板巨大表面储存大量电荷,只要增大中间隔膜厚度,即可使正负电极池内的正负电荷之间的电势 ...
