Activated carbons and double layer capacitance

Electrochimica Acta, 1996
Abstract The porous structures and electrochemical double layer capacitance of activated carbon microbeads and carbon fibers were investigated using nitrogen gas adsorption and electrochemical constant current cycling (CCC) methods. Porous structural information on pore size distribution (PSD) and surface area were extracted through a gas adsorption ...

The electrochemical double-layer capacitance of yttria-stabilised zirconia [PDF]

open access: yesSolid State Ionics, 2002
The capacitance of the double-layer at the interface between irreversible (current-blocking) gold electrodes and yttria-stabilised zirconia (YSZ) was measured by impedance spectroscopy as a function of the applied electrode potential and yttria content (2–8 mol%).

Roughness effects on the double-layer charge capacitance: the case of Helmholtz layer induced roughness attenuation [PDF]

open access: yesSurface Science, 2003
For electrical double layers, the presence of a Helmholtz layer could lead to electrode roughness attenuation. The latter is assumed of self-affine type which is characterized by the roughness amplitude w, the correlation length xi, and the roughness exponent H.

Double layer in ionic liquids: The nature of the camel shape of capacitance [PDF]

open access: yesElectrochemistry Communications, 2010
Monte Carlo simulations of a model ionic liquid show that if ions have charged heads and neutral counterparts, the latter give rise to the camel shape of the voltage dependence of the double layer capacitance.
