“…In some cases, water is regarded as an impurity that destabilizes the electrochemical window of ILs 37 . However, the addition of water in controlled amounts can reduce the viscosity of the solution, improve the conductivity and thus modify the metal deposition behavior 32,33,35,[38][39][40][41][42] . It was confirmed that by introducing 3 wt% H 2 O into the IL [C 4 mpyr][dca], a higher current density was achieved for the Zn redox reaction along with a more compact and dendrite-free morphology of Zn deposits 43 .…”

The world's mounting demands for environmentally benign and efficient resource utilization have spurred investigations into intrinsically green and safe energy storage systems. As one of the most promising types of batteries, the Zn battery family, with a long research history in the human electrochemical power supply, has been revived and reevaluated in recent years. Although Zn anodes still lack mature and reliable solutions to support the satisfactory cyclability required for the current versatile applications, many new concepts with optimized Zn/Zn 2+ redox processes have inspired new hopes for rechargeable Zn batteries. In this review, we present a critical overview of the latest advances that could have a pivotal role in addressing the bottlenecks (e.g., nonuniform deposition, parasitic side reactions) encountered with Zn anodes, especially at the electrolyte-electrode interface. The focus is on research activities towards electrolyte modulation, artificial interphase engineering, and electrode structure design. Moreover, challenges and perspectives of rechargeable Zn batteries for further development in electrochemical energy storage applications are discussed. The reviewed surface/interface issues also provide lessons for the research of other multivalent battery chemistries with low-efficiency plating and stripping of the metal.

“…The aqueous electrolytes offer fast O 2 redox kinetics, while ionic liquids provide some control in Zn deposition and dissolution . Alternatively, hybrid electrolytes can also be mixtures of large amounts of ionic liquids and small amounts of cosolvents, such as water, benzene or dimethyl sulfoxide . These cosolvents are used to increase ionic conductivity and reaction kinetics of ionic liquids.…”

The century-old zinc-air (Zn-air) battery concept has been revived in the last decade due to its high theoretical energy density, environmental-friendliness, affordability, and safety. Particularly, electrically rechargeable Zn-air battery technologies are of great importance for bulk applications like electric vehicles, grid management, and portable electronic devices. Nevertheless, Zn-air batteries are still not competitive enough to realize widespread practical adoption because of issues in efficiency, durability, and cycle life. Here, following an introduction to the fundamentals and performance testing techniques, the latest research progress related to electrically rechargeable Zn-air batteries is compiled, particularly new key findings in the last five years (2013-2018). The strategies concerning the development of Zn and air electrodes are in focus. The design of other battery components, namely electrolytes and separators are also discussed. Poor performance of O electrocatalysts and the lack of the long-term stability of Zn electrodes and electrolytes remain major challenges. Finally, recommendations regarding the testing routines and materials design are provided. It is hoped that this up-to-date account will help to shape the future research activities toward the development of practical electrically rechargeable Zn-air batteries with extended lifetime and superior performance.

“…Previous reports investigating the redox behaviors of Ag, Cu, Sn, In, and Zn in [BMPyr] [NTf 2 ] or [BMPyr] [Nf 2 ] were referred to for assigning the number of electrons, especially for metals having more than an oxidation state such as Cu and Sn. [25][26][27][28] As the upper limit of dissolution potential for each metal is indicated by arrows in Fig. 2, the arrows are located on initial uphill sections or plateaus of the current density.…”
