“…Same as the electrolytes, the negatively charged functional groups that are grafted on the main chain of the polymer separator may also regulate the Zn 2+ transport. The effect of sulfate‐based, chloride‐based, and nitride‐based functional groups on adjust Zn 2+ diffusion was investigated, and it was found that sulfate‐based groups were the most effective, [ 83 ] making them extensively applied for decorating separators for ZIBs. For example, a zincic perfluorinated sulfonic acid membrane was developed as the separator for aqueous ZIBs.…”

scenario, the utilization of alternative and sustainable energy types, such as solar energy, [2] wind energy, [3] biomass energy, [4] tidal energy, [5] and geothermal energy, [6] is essential. Although these types of energy are generally accessible and clean, the direct storage and transportation of them are extremely difficult, and their highly fluctuating nature makes things even worse. [7] Alternatively, electrical energy is often generated from these energy types and serves as an intermediate between the direct energy harvest and the terminal utilization. In this regard, the development of energy storage systems (ESSs) is essential to provide a more versatile and stable energy supply for individual, household, and industrial applications, which has consequently been extensively investigated. [8] Among all current ESSs, batteries play a major role [9] and have been indispensably utilized for portable electronics, tools, electric vehicles (EVs), and even power grids. [10] Owing to their lightweight, high energy density, and extended cycle life, lithium-ion batteries (LIBs), initially developed in the early 1990s, are regarded as a milestone of ESS technologies. [11] Since then, LIBs have been widely applied, which have reshaped our lifestyle. Despite their success in mass production, commercial LIBs still suffer from high cost due to the limited lithium resource and the high cost of other components (e.g., Co-based cathode), [12] which is further worsened by the rigid requirement for their manufacture. Besides, the safety concerns, which stem from the flammable organic electrolyte and highly reactive lithium species, also significantly hinder the deployment of LIBs on a large scale. [13] Considering these limitations of LIBs, it is necessary to develop alternative ESSs with comparable energy/power density but better costeffectiveness and higher safety characteristics. [14] To achieve this, the exploration of high capacity yet relatively inert anode materials and nonflammable electrolytes is essential. Zinc-ion batteries (ZIBs) have been prospected as a new generation of inexpensive and safe ESS devices. Different from typical LIBs, a ZIB is composed of a Zn 2+ ion storage cathode and a Zn metal anode, which is favorable for high anode capacity. Furthermore, aqueous electrolytes are frequently used for ZIBs rather than the organic ones. [15] As a result, energy is stored and released via the reversible Zn stripping/plating at the anode and Zn 2+ insertion/desertion at Zinc-ion batteries (ZIBs) are regarded as a promising candidate for next-generation energy storage systems due to their high safety, resource availability, and environmental friendliness. Nevertheless, the instability of the Zn metal anode has impeded ZIBs from being reliably deployed in their proposed applications. Specifically, dendrite formation and the hydrogen evolution reaction (HER) on the Zn surface significantly compromise the Coulombic efficiency and cycling stability of ZIBs. In recent years, increasing efforts have been devoted t...

“…Compared with the literature results, our battery showcases an outstanding cycling performance (Figure d), although we did not use any sophisticated cell components or electrolytes. When Li-based solid-state electrolytes (SSEs) and Na-based ion-exchange membrane (IEM) were used, , the voltaic battery showed high-capacity retention of ∼100%; however, their cycling numbers are limited to 100–150 cycles. Meanwhile, the SSE or IEM is hard to manufacture and is highly expensive, which markedly limits the practical applications.…”

“…The first one is to replace the conventional separator with a solid-state electrolyte or an ion-exchange membrane (Figure b), − which physically decouple Zn 2+ /Zn and Cu 2+ /Cu reactions. To balance the charge, extra cations or anions must be used to commute between the catholyte and anolyte solutions. − However, these solid electrolytes and membranes are difficult to manufacture and highly expensive. , Moreover, using extra salts and electrolytes dramatically increases the battery mass, which decreases the practical energy density. Additionally, this method makes the battery design complicated to use.…”

Voltaic pile, the very first battery built by humanity in 1800, plays a seminal role in battery development history. However, the premature design leads to the inevitable copper ion dissolution issue, which dictates its primary battery nature. To address this issue, solid-state electrolytes, ion exchange membranes, and/or sophisticated electrolytes are widely utilized, leading to high costs and complicated cell configuration. Herein, we build a rechargeable zinc−copper voltaic battery from simple and cheap electrolyte/ separator materials, thus eliminating the need to use the above components. Notably, our battery leverages the Zn 4 SO 4 (OH) 6 •xH 2 O precipitation in ZnSO 4 electrolytes, a common side reaction in zinc batteries, to provide a "locally alkaline" environment for copper electrodes. Consequently, oxide (O 2− ) anion insertion takes place and readily transforms copper to copper(I) oxide (Cu 2 O) without any copper ion dissolution issue. Therefore, this battery realizes a high capacity of ∼370 mA h g −1 and a long cycling of ∼500 cycles. Our work provides an innovative approach to stabilize anion insertion in metal electrodes for energy storage.

“…The total electrochemical reaction on the cathode and anode could be interpreted as [Zn(s) + Cu 2+ (aq) ⇄ Zn 2+ (aq) + Cu(s)], for which the crossover of the copper ion leads to a direct chemical reaction in the absence of a salt bridge. Efforts have been dedicated to making the Zn–Cu Daniell battery reversible, in which ion-exchange membrane/ceramics are used to prevent Cu crossover in the neutral electrolyte 12 – 14 , or transfer the redox electrochemistry to hydroxyl (OH − ) involved precipitation process to minimize the copper ion dissolution in alkaline electrolyte 15 . The incorporation of CuO and Bi 2 O 3 could further mitigate Cu 2 O passivation for the alkaline Zn–CuO battery, which affords a reversible Zn–CuO alkaline battery 11 .…”

The zinc-copper redox couple exhibits several merits, which motivated us to reconstruct the rechargeable Daniell cell by combining chloride shuttle chemistry in a zinc chloride-based aqueous/organic biphasic electrolyte. An ion-selective interface was established to restrict the copper ions in the aqueous phase while ensuring chloride transfer. We demonstrated that the copper-water-chloro solvation complexes are the descriptors, which are predominant in aqueous solutions with optimized concentrations of zinc chloride; thus, copper crossover is prevented. Without this prevention, the copper ions are mostly in the hydration state and exhibit high spontaneity to be solvated in the organic phase. The zinc-copper cell delivers a highly reversible capacity of 395 mAh g−1 with nearly 100% coulombic efficiency, affording a high energy density of 380 Wh kg−1 based on the copper chloride mass. The proposed battery chemistry is expandable to other metal chlorides, which widens the cathode materials available for aqueous chloride ion batteries.
