“…Aprotic RTILs also offer the extra benefit of modifying Zn deposit morphology, preventing Zn dendrite formation. Smooth Zn deposits were obtained from trimethyl propylammonium bis(trifluoromethanesulfonyl)imide modified with ethylene glycol [71], BMP-TFSI and EMI-TFSI [72] and EMI-DCA [73]. It is interesting that the RTIL cations have an effect on deposit size, while the morphology and growth orientation of deposits are closely related to the RTIL anions.…”

“…29,101 RTILs have been extensively studied as electrolytes for electrodeposition of metals, and the authors suggest the following reviews as an excellent resource for a more in depth discussion of that topic. 4,102 Yamamoto et al 103 were one of the first groups to investigate RTILs for Zn deposition processes, achieving smooth deposits from trimethylpropylammonium ([N 1,1,1,3 ])[NTf 2 ] with EG as an additive. Several groups since have been investigating RTILs specifically for Zn based battery applications.…”

Metal-air batteries are a well-established technology that can offer high energy densities, low cost and environmental responsibility. Despite these favourable characteristics and utilisation of oxygen as the cathode reactant, these devices have been limited to primary applications, due to a number of problems that occur when the cell is recharged, including electrolyte loss and poor efficiency. Overcoming these obstacles is essential to creating a rechargeable metal-air battery that can be utilised for efficiently capturing renewable energy. Despite the first metal-air battery being created over 100 years ago, the emergence of reactive metals such as lithium has reinvigorated interest in this field. However the reactivity of some of these metals has generated a number of different philosophies regarding the electrolyte of the metal-air battery. Whilst much is already known about the anode and cathode processes in aqueous and organic electrolytes, the shortcomings of these electrolytes (i.e. volatility, instability, flammability etc.) have led some of the metal-air battery community to study room temperature ionic liquids (RTILs) as non-volatile, highly stable electrolytes that have the potential to support rechargeable metal-air battery processes. In this perspective, we discuss how some of these initial studies have demonstrated the capabilities of RTILs as metal-air battery electrolytes. We will also show that much of the long-held mechanistic knowledge of the oxygen electrode processes might not be applicable in RTIL based electrolytes, allowing for creative new solutions to the traditional irreversibility of the oxygen reduction reaction. Our understanding of key factors such as the effect of catalyst chemistry and surface structure, proton activity and interfacial reactions is still in its infancy in these novel electrolytes. In this perspective we highlight the key areas that need the attention of electrochemists and battery engineers, in order to progress the understanding of the physical and electrochemical processes in RTILs as electrolytes for the various forms of rechargeable metal-air batteries.

“…On the other hand, RTILs are promising solid electrolyte candidates for rechargeable zinc-air batteries. Compared to conventional alkaline aqueous electrolytes, the exploration of RTIL-based electrolytes shows a wide and stable electrochemical window [25,26], reduces Zn dendrite formation [27,28], and avoids electrolyte drying out due to it's low volatility [29]. Nevertheless, significant challenges such as reducing viscosity, increasing conductivity, and improving oxygen reduction reaction kinetics remain to achieve viable RTIL based reversible Zn air batteries.…”

Zinc-air batteries have been proposed for EV applications and large-scale electricity storage such as wind and solar power. Although zinc-air chemistries batteries are very promising, there are numerous technological barriers to overcome. We demonstrate for the first time, a new rechargeable zinc-air battery that utilizes a molten Li 0.87 Na 0.63 K 0.50 CO 3 eutectic electrolyte with added NaOH. Cyclic voltammetry reveals that a reversible deposition/dissolution of zinc occurs in the molten Li 0.87 Na 0.63 K 0.50 CO 3 eutectic. At 550 °C, this zinc-air battery performs with a coulombic efficiency of 96.9% over 110 cycles, having an average charging potential of ~1.43V and discharge potential of ~1.04V. The zinc-air battery uses cost effective steel and nickel electrodes without the need for any precious metal catalysts. Moreover, the molten salt electrolyte offers advantages over aqueous electrolytes, avoiding the common aqueous alkaline electrolyte issues of hydrogen evolution, Zn dendrite formation, "drying out", and carbonate precipitation.
