Impedance analysis on electric double layer capacitor with transmission line model

Electroactivity of nanoporous platinum depending on the porosity and potential for various electrode reactions

“…S4, this transition frequency of npPt-1, having smaller pores, was observed to be lower than that of npPt-2. This is in good agreement with a previous report on impedance analysis for porous structures via computer simulation [33].…”

Effect of surfactant on the morphology and capacitive performance of porous NiCo2O4

“…Porous carbon as the electrode materials of EDLCs is known to have very high specific surface area (up to 2,500 m 2 g −1 ) but low specific capacitance (up to 280 Fg −1 ) [16]. Conducting polymer materials are considered to have lower specific capacitance than that of metal oxides.…”

Modern Theories of Carbon‐Based Electrochemical Capacitors

“…For instance, mesoporous carbon materials obtained by template methods usually have wormhole structures with circular cross sections ( Figure 5.1a) [19,64]. In such cases, cylindrical pores are generally the assumption for theoretical treatments for physical adsorption of gases [68,69] and impedance spectroscopy [39,70,71]. If the mesopores are assumed to be cylindrical, as shown in Figure 5.5a, solvated counterions may enter the pores and approach the pore walls to form electric double-cylinder A negatively charged micropore of radius b with solvated cations of radius a 0 lining up along the pore axis to form an electric wire-in-cylinder-capacitor (EWCC).…”
