“…Gao, et al reported that the cation was designed by introducing the functionalized group of -SO3H to the cation of the IL, so a salt of N,N,Ntrimethyl butylsulphonate ammonium hydrosulfate was designed [73]. Yonenaga, et al reported that tetrapropylammonium and tetrabutylammonium cationbased ILs exhibited significant amphiphilic characteristics with strong hydrophobic and equally strong hydrophilic contributions with the use of the 1-propanol probing methodology [74]. Fujiwara [83].…”

New materials, which are eco-friendly and have unusual characters, are so attractive with the increasing demand and harmful pollutants amount all over the world. As a solvent, non-evaporate ionic liquids (ILs) have recently captured notable interest due to their magnifical properties. They have been used for distinct purposes such as electrochemistry, separation, lubrication, catalyst, and energy applications. Adding functional groups and/or anion or cation tunability can ensure improved efficiency ILs depends on the application type. The preset paper is primarily focused on the ionic liquids (IL) synthesis, development of functionalized ionic liquids, and their purification process. It also provides a review of the use of ionic liquids as electrolytes in the thermoelectrochemical cells due to the immediate necessity in areas ranging from waste heat conversion to electricity in modern life. Because ionic liquids have hazardous environmental effects, incur high costs, and require complex synthesis and purification process, all must be under control, recovered and optimized. Therefore, understanding their nature has become more important. Additionally, viscosity and conductivity of ILs are an obstacle in experimental studies; besides, the use of redox couples in IL electrolytes must be improved to use in thermoelectrochemical cell applications.
