“…The results obtained in Fig. 7.11 indicate that the LiX-based DESs are a superionic liquid and these solutions become more "ionic" according to the Walden classification with temperature [40]. This observation can be linked, as discussed above, to the low pseudo energy of the viscous flow value associated with this solution, which further suggests the predisposition of this mixture for use as an electrolyte for energy storage application.…”

“…In fact, in this case, ions provide the major contribution to diffusion in the solution. However, for a higher composition range (i.e., ww > 50 % w/w), it is not the case since certain discrepancies have been found between the calculated [40] with permission from Elsevier and experimental diffusion values. In other words, for such concentrations, diffusion in solution is certainly driven by the ion pairs, as well as by neutral species, which renders the Nernst equation invalid for the high composition range (i.e., ww > 50 % w/w).…”

“…In the case of DESs ( Fig. 7.8c) [40], the strong interaction between N-methylacetamide (NMA) and the ion pair explains ion mobility and conductivity. The similarity between the graphs σ = f(xs) reported for each RTMS indicates that the mechanisms of the charge transport must be similar for all investigated IL + solvent binary mixtures.…”

“…The Li[N(Tf) 2 ]-acetamide composite was formerly chosen as the electrolyte applied in the energy storage application by Chen [39]. Thereafter, Anouti et al demonstrated that N-methylacetamide (MAc) was able to decrease the melting point of a complex system containing a molten salt due to its "water-like" physical properties, e.g., a very high-dielectric constant and dipolar moment [40] can be considered as a good H-bond donor for the formulation [40,41]. We also demonstrated that each formulated DES-based electrolyte containing the MAc and a LiX salt (X = [NO 3 ], [N(Tf) 2 ], or [PF 6 ]) allows the realization of energy storage systems as LIBs or EDLC devices that show promising performances even at 80 °C.…”

“…The Walden rule relates to the ionic mobility represented by the equivalent conductivityΛ (Λ = σ/C) to the fluidity η −1 of the medium through which the ions move [71,92]. [40]. The ideal line is obtained on the basis that ions have mobility that is determined only by the viscosity of the medium and that the number of ions present in the equivalent volume is that indicated by the salt composition, i.e., all ions contribute equally.…”

Ionic liquids (ILs) are room-temperature molten salts (RTMS) composed mostly of organic ions that may undergo almost unlimited structural variations. ILs and deep eutectic solvents (DESs) have been applied in various fields, such as electrolytes for lithium ion batteries, redox flow batteries (RFBs), electrodeposition, and electropolishing, and even in fuel cells. This chapter covers the newest aspects of H-donor ILs in applications where their transport properties (ion conductivity, diffusion, and viscosity) are exploited, for example, as electrochemical solvents for energy storage where conventional media, organic solvents (in batteries), or water (in supercapacitors) fail. Metal nanoparticles' (NPs) formulation and stabilization in H-donor RTMS with some unique size, shape, and properties are also discussed. In these decidedly different materials, a mixture with a molecular solvent shows electroactivity that is not exhibited in more traditional systems, creating huge potential for energy storage and electrocatalysis. The remarkable recent increase in the level of interest in RTMS (protic ionic liquids, PILs, and DESs) in academics and industry is illustrated by the rapid growth in the number of publications on the topic (Fig. 7.1), with more than a 100-fold increase observed over the period 2004 to 2014.The first main objective of this chapter is to summarize the synthesis and physical properties of PILs and DESs and discuss their suitability as green solvents for different applications. The second main objective is to review the electrochemical applications of RTMS and discuss their advantages and disadvantages as electrolytes in comparison with an aprotic homologue for energy storage applications. I hope to generate interest in the wider community and encourage others to make use of proton-donor RTMS-PILs and DESs-in tackling scientific challenges.

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.

Deep eutectic electrolytes offer opportunities for tailoring solvation structure and interface chemistry in advanced batteries, but developing deep eutectic electrolytes for high‐performance zinc ion batteries (ZIBs) remains a challenge. Herein, multifunctional dual‐metal‐salt derived ternary eutectic electrolytes (DMEEs) are designed via a supporting salt strategy for dendrite‐free and long‐lifespan ZIBs. DMEEs are constructed by zinc trifluoromethanesulfonate (Zn(OTF)2), supporting salt of lithium bis(trifluoromethanesulfonyl)imide, and neutral ligand of N‐methylacetamide. Noticeably, supporting salt with weak lattice energy not only induces the reconstruction of intermolecular interactions to form ion pairs and ion aggregates but also tailors the Zn2+ solvation structure and solid electrolyte interface (SEI). The developed DMEEs possess a dual‐anion‐rich Zn2+ solvation shell and induce an inorganic‐rich hybrid SEI, which effectively suppresses side reactions and obtains a dendrite‐free Zn anode with high reversibility. Remarkably, Zn//Zn cells demonstrate cycling stability for over 3000 h, and Zn//PANI full cells deliver no significant capacity decay after 5000 cycles at a high current density of 5 A g−1. This work opens a new avenue to design advanced deep eutectic electrolytes, and the deep understanding of solvation structure and SEI offers guidelines for developing high‐performance batteries.
