Nanostructured Carbons: Double-Layer Capacitance and More

Abstract

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.

Charge storage mechanism in nanoporous carbons and its consequence for electrical double layer capacitors

“…ECs are used when there is a high power demand, not only for power buffer and power saving units, but also for energy recovery (Kotz & Carlen 2000;Miller & Burke 2008;Simon & Burke 2008;. Small devices (a few farads) are widely used for power buffer applications or for memory back-up in toys, cameras, video recorders, mobile phones, and so forth.…”

“…These characteristics originate from the way the energy is stored in the batteries and supercapacitors. Accordingly, supercapacitors are particularly appropriate for applications where high power is needed for a few seconds (Miller & Burke 2008;Simon & Burke 2008;. They can also be seen as a complement to Li-ion batteries in applications where both high energy (Li-ion batteries) and high power delivery/uptake (supercapacitors) have to be achieved.…”

Adsorption and anti-corrosion characteristics of vanillin Schiff bases on mild steel in 1 M HCl: experimental and theoretical study

“…where, 3 0 is the vacuum permittivity. 52,53 An increase in inhibitor concentration leads to a higher degree of surface coverage, and thereby reduces the effective value of A. Further, organic inhibitor molecules are adsorbed on the metal surface, replacing pre-adsorbed ions and water molecules.…”

Moderately Concentrated Acetonitrile‐containing Electrolytes with High Ionic Conductivity for Durability‐oriented Lithium‐Ion Batteries

“…Since battery performance depends not only on the bulk resistance of the electrolyte, but also on the resistance of the electrode/electrolyte interface, [6] nonaqueous electrolytes containing acetonitrile (AN), which depicts an excellent property balance between relative dielectric constant and viscosity, have attracted considerable attention for potential application in electric vehicle (EV) batteries [7] . Nonaqueous electrolytes using AN are already widely used in electric double‐layer capacitors [8] . However, AN itself is not stable against electrochemical reduction on the graphite negative electrode.…”
