Space charge distributions of an electric double layer capacitor with carbon nanotubes electrode

A Cellulose Electrolysis Cell with Metal-Free Carbon Electrodes

“…π electron radicals of the carbon basal planes are also susceptible to electrophilic reactions [26,27], which include HER. Acetylene black (AB), Vulcan, and KB were tested as possible cathode catalysts at a temperature of 150 • C. The I-V characteristics increased in the order of KB > Vulcan > AB ( Figure S1a), which agrees especially well with the order of pore volume and average pore diameter (Table S1 [28,29]) that influences the gas removability and ionomer wettability of the electrode, as reflected by the impedance spectra of the electrolysis cells using these cathodes ( Figure S1b). To examine carbon species with different pore structures, commercially available mesoporous carbon materials (MH, MJ10, 30, and 150) were used in place of carbon blacks.…”

Preparation and Electrochemical Performance of CNT Electrode with Deposited Titanium Dioxide for Electrochemical Capacitor

“…The lower capacitance is partially attributed to poor wettability of electrode material, which leads to a lower usable specific surface area for charge storage. 18 As another reason, polarization may reduce charge accumulation of the ions on the double-layer. For these reasons, reducing the polarization of activated carbon by introducing TiO2 nanoparticles has been considered to be an effective approach to improve the capacitance of the double-layer capacitors.…”
