摘要: Ionic liquids (ILs) have been proven to be promising electrolytes for electrochemical energy storage devices such as supercapacitors and lithium ion batteries. In the last years, due deficiency in of on earth, innovative systems, sodium-based devices, attracted considerable attention. IL-based proposed also these devices. Nevertheless, case advantages limits need further investigated. this work we report an investigation about chemical-physical properties mixtures containing bis(2-methoxyethyl)ether diglyme (2G), which is presently considered one most interesting solvents ionic 1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (Pyr14TFSI) 1-butylpyrrolidinium (PyrH4TFSI). The conductivities, viscosities, densities several 2G ILs Furthermore, their impact behaviour activated carbon composite electrodes has considered. results indicate that are realization advanced devices.Ionic ha...
