Accurate Simulations of Electric Double Layer Capacitance of Ultramicroelectrodes
Microelectrodes and ultramicroelectrodes (UMEs) have been the subjects of intense studies in electrochemical sensing 9 and in electrical energy storage and conversion. 21 Microelectrodes and ultramicroelectrodes refer to electrodes with characteristic sizes less than 25 μm. 6 These electrodes have been used extensively in different scanning probe microscopy techniques. 28 For example, scanning ...
متن کامل2001: 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 capacitance between an ionic liquid and few-layer graphene
Ionic-liquid gates have a high carrier density due to their atomically thin electric double layer (EDL) and extremely large geometrical capacitance Cg. However, a high carrier density in graphene has not been achieved even with ionic-liquid gates because the EDL capacitance CEDL between the ionic liquid and graphene involves the series connection of Cg and the quantum capacitance Cq, which is p...
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...
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...
