Batteries, Journal Year: 2025, Volume and Issue: 11(4), P. 147 - 147

Published: April 9, 2025

This review aims to provide an up-to-date report on the state of art electrolytes based (quasi-)ionic liquids for sodium batteries. Electrolytes conventional ionic are classified into one-anion- and two-anion-type according number different anions present in media. Their application sodium-based batteries is revised, potential advantages highlighted rationalized higher tunability interactions among electrolyte components enabled by presence two anionic species. Next, synthesis properties liquid ammonia solvates (aka ammoniates) presented, with a focus their use as alternative electrolytes. Attention paid some outstanding ammoniates, notably, high conductivity concentrations, together ability sustain dendrite-free deposition, not only but also copper collectors. Finally, prospects limitations these development new batteries, including anode-less devices, discussed.

Investigation of the double layer structure of 1-butyl-3-methylimidazolium thiocyanate at the air–water interface using sum-frequency generation vibrational spectroscopy

The Journal of Chemical Physics, Journal Year: 2024, Volume and Issue: 161(13)

Published: Oct. 1, 2024

The interfacial structure and adsorption behavior of 1-butyl-3-methylimidazolium thiocyanate ionic liquids (ILs) aqueous solutions were investigated using sum-frequency generation vibrational spectroscopy (SFG-VS) surface tension measurements. Polarization-dependent measurements revealed a dramatic increase in the SFG signal for both CH CN stretching modes with increasing ILs concentration, reaching maximum at mole fraction 0.01. This concentration dependence was accompanied by drop tension. Upon further varied slightly reached constant value, while decreased significantly. Quantitative polarization analysis showed that as bulk increased, apparent molecular orientation SCN− transition dipole interface changed from 51° to 46°, tilt angle CH3 group butyl chain attached imidazole cationic ring 18° 32°. decrease can be explained formation double layer air/water interface. It also demonstrated anions adsorbed simultaneously group, rather than successive proposed previous study. Using Shereshefsky model, thermodynamic Gibbs free energy deduced data compared results.

Rational Design of Epoxy Functionalized Ionic Liquid Electrolyte Additive for Hydrogen- and Dendrite-Free Aqueous Zinc Batteries

Published: Jan. 1, 2024

Despite the high safety and low cost associated with aqueous Zn-ion batteries (ZIBs), uncontrolled Zn dendrite growth parasitic reactions induced by water significantly diminish their stability. Herein, a new epoxy functionalized ionic liquid, 4-methyl-4-glycidylmorpholin bis[(trifluoromethyl)sulfonyl]imide (MGM[TFSI]), has been developed to mitigate reactivity for stable ZIBs. It was found that MGM+ cation disrupts hydrogen bond network of water, hindering its adsorption on anodes, thereby suppressing decomposition enhancing anode Additionally, preferential cations surface mitigates tip effects, suppresses growth, promotes formation ZnF2 solid electrolyte interphase layer, effectively isolating from bulk electrolyte. As result, benefiting well-designed MGM+-based electrolyte, Zn//Zn cells achieve enhanced cycling stability, lasting over 2000 h at 1 mA cm-2 mAh cm-2. Furthermore, Zn//MnO2 full deliver remarkable retaining approximately 89% initial capacity after 3000 cycles 5 A g-1. This work proposes MGM[TFSI] additive can regulate interfacial chemistry anode, providing an opportunity design advanced electrolytes highly reversible ZIBs beyond.
