Redox-active electrolyte for carbon nanotube-based electric double layer capacitors
The specific capacitance of the MWCNTs was improved by the addition of an electrochemically active compound (Indigo carmine) to an electrolyte generally used in electric double layer capacitors. The pseudocapacitive contribution of the IC trebled the specific capacitance values of the MWCNTs at low current densities (from 17 Fg to 50 Fg). The good resistance obtained for the MWCNT-based capacit...
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...
متن کاملPhenolic carbon cloth-based electric double-layer capacitors with conductive interlayers and graphene coating
Phenolic resin-derived activated carbon (AC) cloths are used as electrodes for large scale electric double-layer capacitors (EDLCs) or supercapacitors. To increase the energy and power density of the supercapacitor, the contact resistance between the carbon cloth and the aluminum foil current collector is reduced by modifying the Al current collectors. Different modified Al current collectors, ...
متن کاملCarbon Nanotube Capacitors
Capacitors are important components in many integrated circuits. They serve numerous roles in analog and mixed signal circuits, including switched capacitor filters and sampleand-hold circuits. In addition, capacitors provide a vital role in the decoupling of microprocessors, digital signal processors, and microcontrollers from power supply variations. Traditional integrated circuit capacitors ...
متن کاملThermal effects of asymmetric electrolytes in electric double layer capacitors
This study presents a thermal model, derived from first principles, for electric double layer capacitors (EDLCs) with multiple ion species and/or asymmetric electrolytes. It accounts for both irreversible and reversible heat generation rates resulting from the transient electrodiffusion of ions within the electrolyte. Detailed numerical simulations of EDLCs with planar electrodes and binary and...
