Ether-Bond-Containing Ionic Liquids as Supercapacitor Electrolytes
Electrochemical capacitors (ECs) are electrical energy storage devices that have the potential to be very useful in a wide range of applications, especially where there is a large disparity between peak and average power demands. The use of ionic liquids (ILs) as electrolytes in ECs can increase the energy density of devices; however, the viscosity and conductivity of ILs adversely influence th...
متن کاملIonic liquids containing tricyanomethanide anions: physicochemical characterisation and performance as electrochemical double-layer capacitor electrolytes.
We investigated the use of fluorine free ionic liquids (ILs) containing the tricyanomethanide anion ([C(CN)3]) as an electrolyte in electrochemical double-layer capacitors (EDLCs). Three cations were used; 1-butyl-3-methylimidazolium ([Im1,4]), N-butyl-N-methylpyrrolidinium ([Pyr1,4]) and N-butyl-N-methylpiperidinium ([Pip1,4]). Their physicochemical properties are discussed alongside with thei...
متن کاملElectrochemistry of magnesium electrolytes in ionic liquids for secondary batteries.
The electrochemistry of Mg salts in room-temperature ionic liquids (ILs) was studied using plating/stripping voltammetry to assess the viability of IL solvents for applications in secondary Mg batteries. Borohydride (BH4(-)), trifluoromethanesulfonate (TfO(-)), and bis(trifluoromethanesulfonyl)imide (Tf2N(-)) salts of Mg were investigated. Three ILs were considered: l-n-butyl-3-methylimidazoliu...
متن کاملSupercapacitors Based on Carbon Materials and Ionic Liquids
Este artigo descreve o desempenho de supercapacitores construídos a partir de diferentes materiais de carbono. São descritos também o princípio geral de supercapacitor e a fórmula associada com sua operação. A função da nanotextura de carbono é enfatizada, selecionando carbonos preparados por técnicas de moldagem. Foi demonstrado que, principalmente, microporos e pequenos mesoporos são importan...
متن کاملMixtures of protic ionic liquids and propylene carbonate as advanced electrolytes for lithium-ion batteries.
In this study we investigated the chemical-physical properties of mixtures containing the protic ionic liquid (PIL) N-butyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide (PYRH4TFSI), propylene carbonate (PC) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in view of their use as electrolytes for lithium-ion batteries (LIBs). We showed that these electrolytic solutions might display c...
