Electrochemical Windows of Room‐Temperature Ionic Liquids

Investigation of the Effect of Functional Group Substitutions on the Gas-Phase Electron Affinities and Ionization Energies of Room-Temperature Ionic Liquids Ions using Density Functional Theory

“…This is consistent with experimental evidence that ILs containing these aliphatic cations are in general more stable against reduction as compared to ILs containing the aromatic cations. [31,32] Our results also predict imidazolium-based cations to have better cathodic stability than pyridinium-base cations, which is consistent with a comparison of experimentally measured cathodic and anodic stabilities of several IL systems (corrected to a common ferrocene reference) compiled by Matsumoto [33].…”

Investigating the electrochemical windows of ionic liquids

“…The EW is a term that is commonly used to indicate the potential range and the potential difference. It is calculated by subtracting the reduction potential (cathodic limit) from the oxidation potential (anodic limit) [2]. In other words, EW is the voltage range between which the tested substance does not get oxidized nor reduced, i.e.…”

“…Usually, linear sweep voltammetry (LSV) and CV are used for the estimation of EW for ILs, similar to conventional electrolytes [2][3][4].…”

“…The reductive limits of the studied ILs were found to follow the sequence of [ arbitrarily. In many studies, the cut-off current density is usually selected between 0.1 and 1.0 mA/cm 2 [2,4,7,10,11]. Many studies were conducted to screen the EWs of ILs as this is the first step to know the suitability of studied ILs for the targeted electrochemical applications [3,4,[12][13][14][15].…”

Anionic effect of ionic liquids electrolyte on electrochemical behavior of ferrocenylthiol/alkanethiol binary SAMs

“…Most ILs have a wider potential window (up to $5 V) and a higher thermal stability (up to 450°C) [16,17], so the use of ILs would maximize the performance of electrochemically active SAMs and contribute to their long-term stability when applied to some electronic devices. Although studies are in progress concerning the combination of SAMs and ILs such as SAMs formation in ILs [18], desorption behavior in ILs [19,20], and redox behavior in ILs [21], a comparative study on the redox behavior of electrochemically active SAMs in several different types of ILs has not been conducted so far.…”
