In this study, we report the electrical response of two sets of solid-state fractional-order electrochemical capacitors for which the low-frequency impedance phase angle can be tuned from − 69 ° to − 7 °. The configuration makes use of a gel electrolyte in which carbonaceous additives (graphite or reduced graphene oxide) are dispersed at different proportions. Such a disordered electrolyte structure results in subdiffusive charge transport and thus a frequency dispersive capacitive-resistive behavior typical of a constant phase element, which can be useful for both frequency applications and energy storage purposes.In this study, we report the electrical response of two sets of solid-state fractional-order electrochemical capacitors for which the low-frequency impedance phase angle can be tuned from − 69 ° to − 7 °.

具有可调低频阻抗相位角和储能能力的分数阶双电层电容器

在这项研究中，我们报告了两组固态分数阶电化学电容器的电响应，其低频阻抗相角可以从 - 69° 调整到 - 7°。该配置使用凝胶电解质，其中碳质添加剂（石墨或还原氧化石墨烯）以不同的比例分散。这种无序的电解质结构导致亚扩散电荷传输，从而导致恒相元件典型的频率色散电容-电阻行为，这对于频率应用和能量存储目的都是有用的。 在这项研究中，我们报告了两个的电响应一组固态分数阶电化学电容器，其低频阻抗相位角可以从 - 69° 调整到 - 7°。该配置使用凝胶电解质，其中碳质添加剂（石墨或还原氧化石墨烯）以不同的比例分散。这种无序的电解质结构导致亚扩散电荷传输，从而导致恒相元件典型的频率色散电容-电阻行为，这对于频率应用和能量存储目的都是有用的。
