“…It has been reported that the presence of chloride in an ionic liquid substantially increases its viscosity, whereas the presence of water reduces it [5]. Water can also alter the mass transport properties [6,9,10] and the reactivity of some electroactive substrates in RTILs [11][12][13]. Therefore, water is in practice not only an impurity in RTILs, but a rather important modifier of their chemical reactivity.…”

“…For voltammograms recorded in the pure ionic liquids, the reference electrode was a non-aqueous reference electrode kit (BASI Analytical, USA) containing an Ag wire immersed in 0.01 M Ag[NO 3 ] in [Emim][NTf 2 ]. 31 The potentials reported are with respect to the reference electrode. The voltammogram were produced with the software NOVA 1.10 and Origin 8.…”

Ionic liquids can be used as non-volatile, tunable solvents, extractants and electrolytes. This work investigates their ability to extract an organic analyte, capsaicin, from fresh Capsicum annuum Bird's eye chilli peppers (also known as Thai chillies), followed by the electroanalytical quantification of the extracted analyte. Ascorbic acid (vitamin C) was also extracted and quantified. Two ionic liquids were identified to extract capsaicin from fresh chilli more effectively than the conventional ethanol-based process; the inherently basic 1-ethyl-3-methylimidazolium acetate, [Emim] [OAc], and the inherently acidic 1-ethyl-3-methylimidazolium hydrogen sulfate, [Emim] [HSO 4 ]. The ionic liquid extracts could be electrochemically quantified using a bare glassy carbon electrode either in the pure ionic liquid (one pot extraction and quantification) or after dilution with water/ ethanol to assist resolution of the capsaicin (flavour indicator) and ascorbic acid (freshness indicator) features.

“…[142] Studies have shown that cations and anions can be fine-tuned to control their solvation properties and improve electrochemistry and eliminate the growth of dendrites on the Zn anode. [142,143] Highly concentrated RTILs electrolytes are known for their ability to enhance mass transport, thereby improving overall performance in RZABs. [144] The RTILs can also serve as additives to the Zn anode to increase the efficiency and durability of RZABs.…”

“…[144] The RTILs can also serve as additives to the Zn anode to increase the efficiency and durability of RZABs. [142][143][144] For example, Ghazvini et al [145] reported the formation of electroactive Zn species at high concentrations of Zn acetate (ZnOAc) 2 ) (> 4.0 M) with an RTIL (I-ethyl-3-methylimidazolium acetate (C 2 mim)(OAc)) additive to facilitate Zn deposition/stripping. However, the drawback was that the electrochemistry was carried out at a high temperature due to the high viscosity of the high concentrations of the RTILs.…”

Efforts at Enhancing Bifunctional Electrocatalysis and Related Events for Rechargeable Zinc‐Air Batteries

et al. 2021

Rechargeable zinc-air batteries (RZABs) are one of the most promising next-generation energy-storage technologies for stationary applications (home and industry), wearable and portable electronics, and transportation (including electric vehicles) due to their high energy density, environmental friendliness, safety, and low cost. However, RZABs still face serious challenges (such as sluggish oxygen reactions, poor durability, inferior reversibility of the zinc anode, and low cell energy efficiency) that conspire against their widespread commercialization. The reactions that occur at the three key components of the RZAB (air cathode, zinc anode, and electrolyte) cooperatively conspire against its performance. Thus, this review focuses on the bifunctional electrocatalytic events at the cathode (i. e., oxygen reduction reaction (ORR) and oxygen evolution reaction (OER)). That is in addition to the recent developments aimed at mitigating the performance-limiting events at the anode and the electrolytes. This review directs the attention of researchers and users to the critical areas for the development of the next-generation RZABs.
