“…[Mg(G2) n ] 2+ ) like Li + -glyme complexes. [31][32][33] If Mg 2+ -glyme complex cations were formed, they may more easily access the cathode surface compared to [Mg(Tf 2 N) 3 ] − because of the electrostatic attractions with cathode. Another possibility is that the complex of Mg 2+ and Tf 2 N − can hardly desolvate because of electrostatic attraction, while glymes with neutral charge may more easily desolvate from Mg 2+ , even though it should be thermodynamically disadvantageous compared to Tf 2 N complex.…”

The electrodeposition of Mg metal from an ionic liquid-glyme mixture was investigated at room temperature. The mixture contains a glyme, a simple amide salt Mg(Tf 2 N) 2 (Tf = SO 2 CF 3), and a quaternary-ammonium Tf 2 N ionic liquid. Using the mixture bath, substantial cathodic electrodeposition of Mg at a large current density (∼10 mA cm −2) was observed, suggesting a change in coordination geometry around Mg 2+ cation together with improved conductivity. By mixing diglyme, the conductivity increased by an order of magnitude (2.5-2.6 mS cm −1) compared to the glyme-free ionic liquid (0.35 mS cm −1) and the viscosity became as low as that of pure glyme. Additionally, potentiostatic electrolysis resulted in a non-dendritic thin film of elemental Mg with metallic luster.

“…Plewa et al 161 constructed the composite electrolytes comprising polyglyme ( M w = 500), LiX (X = I − , BF 4 − and CF 3 SO 3 − ) and calix[6]pyrrole derivative (C6P), and focused on the role of C6P as an anion complexing agent. To probe the potential use of tin as an alternative anode material for rechargeable lithium batteries, Katayama et al 162 examined the charge–discharge property of a tin thin film electrode in an ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide containing 0.1M Li[Tf 2 N]. To reduce the interfacial resistance in the ionic liquid electrolyte, a small amount (0.2 M) of glymes (mono-, di-, tri- and tetra-) was added to coordinate with Li + ions.…”

An early study by Aurbach and Granot 164 suggested that electrolytes consisting of various lithium salts and glymes (monoglyme, diglyme and ethyl glyme) might not be suitable for rechargeable Li battery systems using Li metal anodes due to a rough morphology of Li upon deposition-dissolution cycling causing a low Li cycling efficiency.…”

Glymes as versatile solvents for chemical reactions and processes: from the laboratory to industry

Glymes, also known as glycol diethers, are saturated non-cyclic polyethers containing no other functional groups. Most glymes are usually less volatile and less toxic than common laboratory organic solvents; in this context, they are more environmentally benign solvents. However, it is also important to point out that some glymes could cause long-term reproductive and developmental damages despite their low acute toxicities. Glymes have both hydrophilic and hydrophobic characters that common organic solvents are lack of. In addition, they are usually thermally and chemically stable, and can even form complexes with ions. Therefore, glymes are found in a broad range of laboratory applications including organic synthesis, electrochemistry, biocatalysis, materials, and Chemical Vapor Deposition (CVD), etc. In addition, glyme are used in numerous industrial applications, such as cleaning products, inks, adhesives and coatings, batteries and electronics, absorption refrigeration and heat pumps, as well as pharmaceutical formulations, etc. However, there is a lack of comprehensive and critical review on this attractive subject. This review aims to accomplish this task by providing an in-depth understanding of glymes’ physicochemical properties, toxicity and major applications.

“…Herein, we investigate the EDL of an IL interface with incorporation of small amounts of water molecules by using electrochemical techniques and AFM‐based force curve measurements under potential control. The Au(111)/1‐butyl‐1‐methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) interface was chosen because the BMPTFSA IL has potential applications in lithium‐ion battery technology . By investigating the potential‐dependent layering structure of BMPTFSA, including the number, thickness, and stability of the layers at different water concentrations, a better understanding of the role of small amounts of water in the structure of the EDL of the Au(111)/IL interface could be achieved.…”

Electrochemical techniques and atomic force microscopy based force curve measurements under potential control are combined to investigate the effect of small amounts of water on the structure of the electric double layer of an Au(111)/1‐butyl‐1‐methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) interface. Three to five layering structures, including two charged layers, are observed at the Au(111)/BMPTFSA interface at potentials more negative than the point of zero charge. With an increase in the water concentration, the stiffness values for both the first and second layers decrease, which demonstrates that more water molecules adsorb on the Au(111) surface or interact with the ionic liquid, and thus weaken the interactions between cations, anions, and the electrode surface and lower the stability of the layering structures. The thicknesses of the charged interior layers (the first and second layers in this system) increase with an increase in the water concentration and the thicknesses of neutral exterior layers (the next one to three layers in this system) remain almost unchanged. The structure of the first layer of the interface varies dramatically with the change in the water concentration.
