“…All these features make rechargeable Zn-based devices promising and attractive candidates to take over the market of next-generation energy storage technologies. Despite all the positive properties and regardless of the cathode chemistry (e. g. Zn-ion, [9,11,12] Znair, [1,13,14] Zn-hybrid [15][16][17] ), they suffer from severe anode degradation upon cycling, which has prevented it widespread commercialization. Several factors affect the performance of Zn as anode, which include H 2 evolution (causing self-discharge), surface passivation and shape changes and/or dendritic growth due to non-uniform current distributions.…”

As the interest in alternative Li‐based energy storage technologies increased during the last years, zinc emerged as a promising candidate. Despite several advantages over Li, Zn cycling stability is still a major issue. In this article, the use of near‐neutral electrolytes (non‐expensive 2 M ZnSO4) with the addition of different additives (dimethylsulfoxide and tetratethylammonium chloride) is proposed as a solution. The Zn deposition/dissolution electrochemistry has been evaluated and the cycling stability was determined in Zn//Zn symmetric coin‐cells. Hybrid supercapacitors were also assembled and tested in a range of 0.2 V–1.8 V for 2000 cycles, using activated carbon electrodes as cathode and Zn foil as anode. The results show that dimethylsulfoxide strongly inhibits the Zn deposition process, evidenced by a decrease in the cathodic current density, as well as in the dissolution peak. DMSO affects the deposition mechanism, whereas tetratethylammonium chloride reduces the exchange current density, consistent with the adsorption of tetraethylammonium ions on the Zn surface. A synergy between both additives leading to further inhibition of Zn2+ reduction is observed allowing cycling up to 250 hours for Zn//Zn devices. In addition, the performance of hybrid supercapacitors has also improved showing better capacity and extended cycle life.

“…Recently, aqueous batteries (ABs) were proposed as a safer and cheap alternative for LIBs, SIBs, and PIBs, particularly for stationary applications. [13][14][15] The ABs with water-based electrolytes offer advantages over conventional organic batteries, such as low cost, environmental benignity, fast charging ability, and high-power densities. Different merits of the aqueous electrolyte over organic electrolyte are summarized in Figure 1a.…”

Improving the energy share of renewable energy technologies is the only solution to reduce greenhouse gas emissions and air pollution. The high‐performing green battery energy storage technologies are critical for storing energy to address the intermittent nature of renewable energy resources. In recent years, aqueous batteries, particularly the Zn‐ion batteries (ZIBs), have achieved and shown great potential for stationary energy storage systems owing to their low cost and safer operation. However, the practical applications of the ZIBs have significantly been impeded due to the gap between the breakthroughs achieved in academic research and industrial developments. The present review discusses the ZIB's advantages, possibilities, and shortcomings for stationary energy storage systems. The review begins with a brief introduction to the ZIBs and their charge storage mechanisms based on the structural properties of cathode materials. The scientific and technical challenges that obstruct the commercialization of the ZIBs are discussed in detail concerning their impact on accelerating the utilization of the ZIBs for real‐life applications. The final section highlights the outlook on research in this flourishing field.
