The present work addresses a new finding observed while performing aluminum dissolution experiments for supercapacitors (SCs) stability investigation. Supercapacitor (SC) electrodes based on carbon-coated foils are electrochemically cycled in harsh conditions into bis-trifluoromethylsulfonyl imide (TFSI)-based electrolyte and using Acetonitrile (ACN) as solvent. Dissolution of is with subsequen...

Abstract New experimental vapor pressures in the range 407 K to 460 and vaporization enthalpy of ionic liquids (IL) N -alkyl- -methyl-pyrrolidinium bis(fluorosulfonyl)imide have been measured using quartz crystal microbalance. The absolute enthalpies were compared with analogous pyrrolidinium-based ILs bis(trifluoromethanesulfonyl)imide anion. evaluated difference anions allowed for estimation ...

Organic-inorganic metal-halide perovskite solar cells (PSCs) have achieved a certified power-conversion efficiency (PCE) of 25.5%. However, long-term stability and air the PSCs are still major concerns hamper commercialization. Herein, we employ multi-functional ionic liquid (IL), 1,3-bis(cyanomethyl)imidazolium bis(trifluoromethylsulfonyl)imide ([Bcim][TFSI]), which contains an imidazolium cat...

Rechargeable magnesium batteries are poised to be viable candidates for large-scale energy storage devices in smart grid communities and electric vehicles. However, the energy density of previously proposed rechargeable magnesium batteries is low, limited mainly by the cathode materials. Here, we present new design approaches for the cathode in order to realize a high-energy-density rechargeabl...

The application of room-temperature ionic liquids (RTILs) in nuclear spent fuel recycling requires a comprehensive knowledge of radiation effects on RTILs. Although preliminary studies indicate a relatively high radiation stability of RTILs, little attention is paid to the color change of RTILs, an obvious phenomenon of RTILs during irradiation. In this paper, we have investigated radiation-ind...

The management of proton conductivity in the protic ionic liquid imidazolium bis(trifluoromethylsulfonyl)imide ([Im][TFSI]) is investigated via the use of quasi-elastic neutron scattering (QENS) and pulsed-field gradient NMR. The introduction of excess neutral imidazole to [Im][TFSI] leads to enhanced conductivity. We find that proton dynamics in [Im][TFSI] with excess imidazole are characteriz...
