| 摘 要： | 为了精确表征双电层超级电容器在静态储能过程中的电荷分布情况及其时间常数,根据电磁场理论建立了一种矩阵式系数的数学模型.所建立的模型以四阶矩阵中的元素来描述双电层电容量与其上电压、电荷的关系,并且各元素值只与电极材料有关.该建模方法所需参数少,同时从原理上揭示了双电层超级电容器独特的储电机理和自放电特性,从根本上解释了在...

| Abstract: | In order to precisely characterize the charge distribution and time constant of the double-layer super-capacitor during the static energy storage,a mathematical model that had a matrix coefficient based on the electromagnetic theory were established.The elements of the fourth-order matrix model describe the relationship between the capacitance and the voltage and charge of the double-layer super-capacitor,and the values of the matrix elements are merely relevant with the electrode materials.This novel model... |
