Special Issue Information

Dear Colleagues,

Ionic liquids (ILs) are ionic compounds that are primarily used as solvents or electrolytes. For liquid phase extraction, clean technology, catalysis, polymerization processes, liquid chromatography mobile phase additives, extraction solvents, surface-bonded stationary phases, and supported IL membranes, ILs are widely regarded as viable alternatives to traditional organic solvents.

ILs are also widely used in energy storage devices such as supercapacitors and batteries. ILs are important electrolytes due to their high ionic conductivity and wide stability window. Because ILs have a low vapor pressure and are nonflammable, they could play an important role in resolving the instability of lithium-ion secondary batteries. They are also frequently used in the process of synthesis of an energy storage device’s electrode material.

The purpose of this Special Issue is to assemble original research work that highlights the applications of "Ionic Liquids and Their Analogs" in separation or electrochemical processes, with a focus on solvents and electrolytes properties. This issue will focus on a detailed study of the synthesis and characterization of ionic liquids/analogs, as well as the ionic transport mechanism. We invite original research papers, communications, and review articles presenting recent developments and trends in the synthesis, characterization, and applications of ionic liquids/analogs as solvents or electrolytes, with a preference for separation processes and electrochemical applications.

Antimony (Sb) is a potential candidate anode for potassium-ion batteries (PIBs) owing to its high theoretical capacity. However; in the process of potassium alloying reaction; the huge volume expansion (about 407%) leads to pulverization of active substance as well as loss of electrical contact resulting in rapidly declining capacity. Herein; uniformly dispersed Sb-Nanodot in carbon frameworks (Sb-ND@C) were constructed by in situ confined polymerization of ionic liquids. Attributed to the uniformly dispersed Sb-ND and confinement effect of carbon frameworks; as anode for PIBs; Sb-ND@C delivered a superior rate capability (320.1 mA h g−1 at 5 A g−1) and an outstanding cycling stability (486 mA h g−1 after 1000 cycles; achieving 89.8% capacity retention). This work offers a facile route to prepare highly dispersed metal-Nanodot via the in situ polymerization of ionic liquid for high-performance metal-ion batteries Full article
