Room Temperature Ionic Liquids
The initial objective of this project was to carry out a fundamental study of the transport characteristics of a variety of gases and organic solutes in room temperature ionic liquids. The goal was to combine information collected from a number of different experimental measurements in order to develop a fundamental understanding of the interactions governing transport in ionic liquids. Measure...
متن کامل"Ionic liquids-in-salt"--a promising electrolyte concept for high-temperature lithium batteries?
A novel electrolyte concept for lithium-ion batteries, termed "ionic liquid-in-salt", is introduced. Our feasibility study on (1 - x)EMIMTFSI:(x)LiTFSI, 0.66 ≤ x ≤ 0.97, showed that at elevated temperatures the various dual liquid and solid phase regions are characterized by a wide thermal stability window, high ionic conductivities and appreciable mechanical integrity. The highest conductivity...
متن کاملDynamic Heterogeneity in Room-Temperature Ionic Liquids
Room temperature ionic liquids (RTILs) are comprised of bulky organic cations and anions (Holbrey & Seddon, 1999; Weingärtner, 2008). Because of the intricate interplay of various interand intramolecular interactions, RTILs have rich dynamical properties and have found diverse applications. In particular, negligible vapor pressure of RTILs makes them a green alternative of conventional organic ...
متن کاملElectrochemical Applications of Room - Temperature Ionic Liquids
R3 R2 There is good evidence that the first room-temperature ionic liquid or RTIL was identified and characterized by Walden in 1914, who examined the electrical conductivity of ethylammonium nitrate.1 Thus, it would not be an exaggeration to say that the very beginnings of electrochemistry involved room-temperature ionic liquids! Although once considered to be a curious subset of the general c...
متن کاملPolystyrene-Al2O3 composite solid polymer electrolyte for lithium secondary battery
In a common salt-in-polymer electrolyte, a polymer which has polar groups in the molecular chain is necessary because the polar groups dissolve lithium salt and coordinate cations. Based on the above point of view, polystyrene [PS] that has nonpolar groups is not suitable for the polymer matrix. However, in this PS-based composite polymer-in-salt system, the transport of cations is not by segme...
