Since the research direction of supercapacitors (SC) has been deviated from the principle of causing capacitance, the revisit may be a future task in exploiting electric power storage. SC have been developed by applying ionic properties in order to enhance heterogeneity of ionic distributions. However, SC belong to double-layer capacitances (DLC), which are caused by orientation of solvent dipoles without any direct relation to ionic properties. DLC are always complicated with ion-independent characteristics such as frequency dispersion, voltage dependence, and participation in redox reactions, whereas these complications have not yet been considered in development of SC. Especially, pseudo capacitances should be examined through isolating the contribution of DLC from the redox properties.

由于超级电容器（SC）的研究方向已经偏离了引起电容的原理，因此重新研究可能是开发电能存储的未来任务。为了增强离子分布的不均匀性，已经通过应用离子特性开发了SC。但是，SC属于双层电容（DLC），它是由溶剂偶极子的取向引起的，与离子性质没有任何直接关系。DLC总是具有独立于离子的特性，例如频率分散，电压依赖性和参与氧化还原反应，而在SC的开发中尚未考虑这些复杂性。特别是，应该通过将DLC的贡献与氧化还原特性隔离开来检查伪电容。
