2001: ELECTRIC DOUBLE LAYER CAPACITANCE OF POROUS CARBON DERIVED FROM PTFE WITH Li METAL
Recently, electric double layer capacitor (EDLC) with high capacitance [1] has been proposed as a sub-power source for a pure electric vehicle (PEV) or a hybrid electric vehicle (HEV) because power density of EDLC is high enough to use as the power source at start-up of the electric vehicles. However, since energy density of EDLC is quite lower than that of rechargeable batteries, the double la...
متن کاملElectric double-layer capacitor based on an ionic clathrate hydrate.
Herein, we suggest a new approach to an electric double-layer capacitor (EDLC) that is based on a proton-conducting ionic clathrate hydrate (ICH). The ice-like structures of clathrate hydrates, which are comprised of host water molecules and guest ions, make them suitable for applications in EDLC electrolytes, owing to their high proton conductivities and thermal stabilities. The carbon materia...
متن کاملThe electric double layer structure around charged spherical interfaces.
We derive a formally simple approximate analytical solution to the Poisson-Boltzmann equation for the spherical system via a geometric mapping. Its regime of applicability in the parameter space of the spherical radius and the surface potential is determined, and its superiority over the linearized solution is demonstrated.

متن کاملNanostructured Carbons: Double-Layer Capacitance and More
The Electrochemical Society Interface • Spring 2008 This article is concerned with the design and characteristics of electrochemical double layer capacitors (EDLCs), and in particular the role of nanostructured carbons and how they function. EDLCs have been under development for over 20 years, but it is only relatively recently that the mechanisms of energy storage in carbon film electrodes hav...
