Mixtures of unsaturated imidazolium based ionic liquid and organic carbonate as electrolyte for Li-ion batteries

Ionic Liquids at Electrified Interfaces

“…RTILs spontaneously absorb some small amount of water from the air 20,30,38,130,229,231,315,330 or they can be deliberately mixed with some amount of organic solvents (usually for the purpose of increasing the mobility of ions); 35,50,120,[316][317][318][319][320] 1 ≠ " will then characterise the volume portion of those molecules. The case of " = 1 corresponds to an ultra dense system with no voids (or no solvent).…”

Measurement and correlation of electrical conductivity of ionic liquid [EMIM][DCA] in propylene carbonate and γ-butyrolactone

“…Organic solvents, propylene carbonate (PC) and g-butyrolactone (GBL), have high boiling points, low melting points and low vapor pressures [42], which make them as good candidates for improving transport properties of ILs in electrolytes [43,44]. As a result, the mixtures of IL-PC and IL-GBL can improve both electrochemical performance and thermal stability of the electrolytes [43][44][45] [DCA] were confirmed to be less than 300 ppm by Karl Fisher titration.…”

Synthesis and Properties of Alkoxy‐ and Alkenyl‐Substituted Peralkylated Imidazolium Ionic Liquids

“…Hence, the effect of the functionalities on the ECW can be investigated without interference of the imidazolium ring hydrogen atoms, which are all substituted. In general, alkenes induce a minute increase in cathodic stability and a substantial increase in anodic stability,2, 24 whereas the effect of alkoxy groups on the ECW was earlier found to be very small or absent 9a. 11b The anodic ( V an ) and cathodic ( V cat ) limit potentials and the ECWs (Δ V ) of 6 – 11 c are given in Table 6 with a cutoff current density value of 0.25 A dm −2 , which is the value at which all noise can be ignored.…”
