Double layer capacitance of anode/solid-electrolyte interfaces
Physical Chemistry Chemical Physics, 2011The double layer of electrode/electrolyte interfaces plays a fundamental role in determining the performance of solid state electrochemical cells. The double layer capacitance is one of the most-studied descriptors of the double layer. This work examines a case study on lanthanum strontium vanadate (LSV)/yttria-stabilized zirconia (YSZ) interfaces ...

A new model of the differential capacitance of the double layer
Journal of Electroanalytical Chemistry, 1983Abstract We present a new model of the metal-electrolyte interface which takes explicit account of the mobility of electrons at a metallic interface. The model can be described as a simple modification of the classical Stern-Gouy-Chapman double layer theory, but it contains an essential new feature of fundamentally quantum mechanical origin.

An Electrochemical Cell with Capacitance-Enhanced Double Layer
ECS Transactions, 2007Initial studies on the fabrication of a new double-layer capacitor based on hydrated ruthenium oxide (RuO2.xH2O) are presented. The electrochemical capacitor cell is based on three designs approaches: active surface enhancement via corrugations, the use of an ultra-thin self assembled dielectric implemented with hydrated Ruthenium oxide and ...

Theory of Double-Layer Differential Capacitance in Electrolytes
The Journal of Chemical Physics, 1962A theory of the double layer in uni-univalent unadsorbed electrolytes is developed and used to analyze Grahame's experimental measurements of differential capacitance for NaF in water at 0° to 85°C and KF in methanol at 25°C. Excellent agreement with experiment is obtained except in the region of strong anodic polarization; this disagreement is ...

Kramers-Kronig transformation of double-layer capacitances
Surface Technology, 1980Abstract Experimental capacitance data of some mercury/electrolyte contacts were transformed into resistances, losses and spectral densities by application of two different numerical methods of Kramers-Kronig transformation. The first method is based upon a direct integration and the second one upon a Fourier series expansion.

Total double layer capacitances of oxide suspensions
Materials Chemistry and Physics, 1989Abstract Capacitances obtained by differentiation of experimental charge vs pH curves are presented for hematite suspensions both in NaClO4and in KNO3. The adsorption features of the two electrolytes are discussed comparing the variation of the experimental capacitance with that expected on the Stern — Gouy Chapman theory.
