“…As a consequence, green, safe, and low-cost DES electrolytes are being intensively investigated for safety-and energy-enhancing supercapacitors. [88][89][90][91][92][93][94][95][96] Besides, DES electrolytes can afford the operation of supercapacitors at high temperatures, which is desired for some specific applications (e.g., military and aerospace). For example, Zaidi et al developed a new DES electrolyte based on sodium nitrate and NMAc for carbonbased supercapacitors at 80 °C.…”

The pursuit of sustainable energy utilization arouses increasing interest in efficiently producing durable battery materials and catalysts with minimum environmental impact. As green, safe, and cheap eutectic mixtures, deep eutectic solvents (DESs) provide tremendous opportunities and open up attractive perspectives as charge transfer and reaction media for electrochemical energy storage and conversion (EESC). In this review, the fundamental properties of DESs are first summarized. Then, the important roles that DESs play in various EESC technologies including advanced electrolytes for batteries/supercapacitors, media for the preparation of electrode materials and catalysts, and extracting agents for battery recycling are systematically reviewed. A particular focus is placed on the fundamental understanding of structure-composition-property-performance relationships. Finally, the challenges for the controllable design of DESs for EESC applications and future developments are presented. This review is expected to shed light on developing advanced DESs for next-generation EESC systems.

“…More papers were selected and added through forward and backward citation searching. No attempts will be made to cover DES electrolyte applications in supercapacitors, [91][92][93][94][95][96][97][98][99][100][101] dye sensitized solar cells (DSSCs), [102][103][104][105][106] and redox flow batteries. 25,[107][108][109][110][111][112][113][114][115][116][117] Note that, for the reasons explained above, we will include all eutectic mixtures, regardless of the solid or liquid state at above-ambient temperatures of the constituents in their pure states, and of whether a deviation from ideality has been demonstrated.…”

Deep eutectic Solvents (DESs) are an emerging class of materials showing a marked depression in melting points compared to those of the neat constituents and characterized by a number of beneficial properties. DES research currently prospers and out of the multiple current applications, the electrochemistry field is likely the most flourishing. This detailed review emphasizes recent research efforts in order to apply type III and type IV DESs and their analogues as electrolytes for rechargeable cationic batteries. The recent developments in the last decade are outlined, framing outstanding achievements and open questions, and identifying future optimisation directions to overcome the existing challenges.

Background Deep eutectic solvents (DESs) are new types of tunable solvents that have attracted a large scientific community due to their versatile applications and attractive physical properties. Ammonium‐based solvents are widely used in desulfurization processes, but they are toxic and expensive. Thus, to replace the conventional ammonium‐based solvents, this work aims to synthesize novel ammonium–ethylene glycol (EG)‐based ternary DESs (TDESs). The thermophysical properties, such as viscosity, density, acidity, stability, degradation point, melting point, conductivity, refractivity and miscibility, were measured in this study. Results The TDESs were prepared using varying molar ratios ranging from 1:3 to 1:5 by combining a hydrogen bond donor (EG) with ZnCl2 and three ammonium‐based hydrogen bond acceptors, namely ethylammonium chloride, diethylammonium chloride and diethylethanolammonium chloride. It was found that most properties are significantly superior to those of the constituent components of the TDESs. Arrhenius and linear equation fittings with respect to temperatures ranging from 20 to 100 °C predict R2 values close to unity. The viscosity, pH and density decrease while electrical conductivity increases with increasing temperature. Conclusion Such interesting observations are mainly caused by the particles’ excitation phenomena that increase their kinetic energy and volume. Furthermore, the lower melting point of TDESs compared to the constituent components is attributed to the charge delocalization through hydrogen bonding between donor and acceptor molecules. © 2022 Society of Chemical Industry (SCI).
