Double layer capacitance of the platinum group metals in the double layer region
Electrochemistry Communications, 2007 Abstract The interfacial impedance for the platinum-group metals, in simple binary electrolytes, in their so-called double layer region, is generally assumed to be ideally capacitive. In this communication, mainly addressing the Ir(1 0 0) / 0.1 M HCl system, we demonstrate that this is not necessarily the case when the anion of the solute is ...

In situ synthesized heteropoly acid/polyaniline/graphene nanocomposites to simultaneously boost both double layer- and pseudo-capacitance for supercapacitors [PDF]
, 2012 It is challenging to simultaneously increase double layer- and pseudo-capacitance for supercapacitors. Phosphomolybdic acid/polyaniline/graphene nanocomposites (PMo12–PANI/GS) were prepared by using PMo12 as a bifunctional reagent for not only well ...

Theory of volumetric capacitance of an electric double-layer supercapacitor [PDF]
Physical Review E, 2011 Electric double layer supercapacitors are a fast-rising class of high-power energy storage devices based on porous electrodes immersed in a concentrated electrolyte or ionic liquid. As of yet there is no microscopic theory to describe their surprisingly large capacitance per unit volume (volumetric capacitance) of ~ 100 F/cm^3, nor is there a good ...
