Supercapacitors are playing a very important role in offering viable solutions for various requirements. In this paper, we attempt to explain the behaviour of a supercapacitor with the help of models using cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD). We have studied the performance of supercapacitors using transmission line models and analytical models. We have made an effort to model and simulate the behaviour of a supercapacitor fabricated from porous activated carbon as electrode material. Molecular dynamic models help to study the particle size distribution, ionic behaviour etc. The instantaneous conductivity of a supercapacitor using a line transmission model is about 0.10071 S/cm and energy 0.152 J. Moreover, we analyse the variation of capacity of capacitor with the pore size of the electrode. In case of micropores, a constant capacitance value is observed with the change in pore size. The average pore size of activated carbon as an electrode material becomes ~1.21 μm. This is attributed to the fact that the electrode ion boundary falls with the pore size. Further, few samples have been characterized using Electrochemical Impedance Spectroscopy. In analytical models, the charging and discharging properties have been discussed using various circuit models.

超级电容器在为各种要求提供可行的解决方案方面发挥着非常重要的作用。在本文中，我们尝试借助循环伏安法 (CV) 和恒电流充放电 (GCD) 模型来解释超级电容器的行为。我们使用传输线模型和分析模型研究了超级电容器的性能。我们已努力对由多孔活性炭作为电极材料制成的超级电容器的行为进行建模和模拟。分子动力学模型有助于研究粒径分布、离子行为等。使用线传输模型的超级电容器的瞬时电导率约为 0.10071 S/cm，能量为 0.152 J。此外，我们分析了电容器容量随孔隙的变化电极尺寸。如果是微孔，随着孔径的变化观察到恒定的电容值。作为电极材料的活性炭的平均孔径变为~1.21 μm。这归因于电极离子边界随孔径下降的事实。此外，很少有样品使用电化学阻抗谱进行表征。在分析模型中，已使用各种电路模型讨论了充电和放电特性。
