Ion adsorption on the inner surface of single-walled carbon nanotubes used as electrodes for electric double-layer capacitors.
In the present study, ion adsorption on the outer and inner surfaces of single-walled carbon nanotubes (SWCNTs) in different aqueous and organic electrolytes was analysed. It was found that the fundamental properties of tube size and electronic structure, particularly the transition between van Hove singularities (the band gap), reflected by the shape of the cyclic voltammogram and increase in ...
متن کاملNumerical Analysis of Electric Double Layer Capacitors with Mesoporous Electrodes: Effects of Electrode and Electrolyte Properties
A theoretical study is presented of the behavior of electric double layer (EDL) supercapacitors constructed from mesoporous activated carbon electrodes. A threedimensional (3D) computational model is developed to predict the equilibrium charge distribution within the supercapacitor as a function of key electrode and electrolyte properties. The model is based on the modified Poisson− Boltzmann (...
متن کاملSimulation of electric double layer capacitors with mesoporous electrodes: Effects of morphology and electrolyte permittivity
This paper aims to numerically predict the capacitance of electric double layer capacitors (EDLCs) made of mesoporous electrodes consisting of closely packed monodispersed mesoporous carbon spheres in (C2H5)4NBF4/propylene carbonate electrolyte. The model faithfully accounts for the electrode packing morphology and the dependency of electrolyte dielectric permittivity on local electric field. T...
متن کاملSuperionic state in double-layer capacitors with nanoporous electrodes.
In recent experiments (Chmiola et al 2006 Science 313 1760; Largeot et al 2008 J. Am. Chem. Soc. 130 2730) an anomalous increase of the capacitance with a decrease of the pore size of a carbon-based porous electric double-layer capacitor has been observed. We explain this effect by image forces which exponentially screen out the electrostatic interactions of ions in the interior of a pore. Pack...
متن کاملScaling laws for carbon-based electric double layer capacitors
This paper presents scaling laws for the integral capacitance of electric double layer capacitors (EDLCs) supported by rigorous analysis and experimental data for porous carbon-based electrodes. First, dimensionless similarity parameters were identified based on dimensional analysis of the modified Poisson–Boltzmann model for binary and symmetric electrolytes. Then, a correlation for the equili...
