“…Li et al investigated the incorporation of an indium (In) component by mixing zinc powder with an InCl 3 solution. 33 The resulting protective layer served dual functions: corrosion prevention and the promotion of uniform zinc deposition. The strong affinity between zinc and indium favored redeposition of the Zn(002) facet.…”

Aqueous rechargeable zinc-based batteries hold great promise for energy storage applications, with most research utilizing zinc foils as the anode. Conversely, the high tunability of zinc powder (Zn-P) makes it an ideal choice for zinc-based batteries, seamlessly integrating with current battery production technologies. However, challenges such as contact loss, dendrite formation, and a high tendency for corrosion significantly hamper the performance enhancement of Zn-P anodes. This review provides an overview of strategies adopted from various perspectives, including zinc powder optimization, electrode engineering, and electrolyte modification, to address these issues. Additionally, it explores the limitations of existing research and offers valuable insights into potential future directions for further advancements in Zn-P anodes.

“…In consideration of the corrosion and dendrite formation issues on the anode, Li et al 56 successfully developed a mechanically and chemically robust powder Zn/indium (pZn/ In) anode for AZSBs. This inventive anode design integrates an indium (In) layer onto the surface of highly active pZn, serving as both a nucleating agent and corrosion inhibitor (as illustrated in Figure 12a).…”

An aqueous zinc–sulfur battery (AZSB) represents a promising next-generation energy storage technology as a result of its salient features of safety, affordability, and environmental benignity. The incorporation of earth-abundant and environmentally friendly sulfur cathodes, zinc anodes, and aqueous electrolytes, coupled with the high theoretical energy density, positions an AZSB as a cost-effective and scalable technology with potential applications in grid-scale energy storage and portable electronics. This review provides a comprehensive review of the current status of research in AZSBs, discussing challenges faced, recent advances, and future perspectives. The major challenges associated with the aqueous electrolyte, zinc anode, and sulfur cathode are discussed in detail with a rational classification. These challenges limit the performance, cycling stability, and overall efficiency of AZSBs. Various strategies to address these issues, including electrolyte modification and electrode design, are critically analyzed and evaluated. Specifically, the review highlights recent advancements in research, including the development of advanced electrolytes by adding additives and the synthesis of novel electrode materials for enhanced electrochemical performance. Further, the utility of advanced characterization techniques for understanding and predicting the reaction mechanism occurring in an AZSB is reviewed. Along with a review of ongoing research activities in the field, future prospects and potential applications of this novel battery technology are also explored. Overall, this review identifies the need for continued research and development efforts to overcome the remaining challenges and, thus, realize the full potential of AZSBs in practical energy storage applications.

“…Here, we used Zn powders, instead of Zn foils, as the anode materials, because Zn powders have the low material cost, the high efficiency in Zn utilization, the good controlling on the capacity ratio of negative/positive electrodes (N/ P ratio), and the excellent compatibility with commercial protocols (Figure 5a). [19] However, using Zn powders as the anode materials has to face the high instability in the electrolyte, owing to the large specific surface area. [20] As displayed in Figure 5b, the initial Coulombic efficiency (CE) of the asymmetric cells using BE as the electrolyte is about 88.4 % at 6 mA cm À 2 for 3 mAh cm À 2 (depth of discharge (DoD) of Zn: 50 %).…”

Zn metal as one of the promising anodes of aqueous batteries possesses notable advantages, but it faces severe challenges from severe side reactions and notorious dendrite growth. Here, ultrathin nanosheets of α‐zirconium phosphate (ZrP) are explored as an electrolyte additive. The nanosheets not only create a dynamic and reversible interphase on Zn but also promote the Zn2+ transportation in the electrolyte, especially in the outer Helmholtz plane near ZrP. Benefited from the enhanced kinetics and dynamic interphase, the pouch cells of Zn||LiMn2O4 using this electrolyte remarkably improve electrochemical performance under harsh conditions, i.e. Zn powders as the Zn anode, high mass loading, and wide temperatures. The results expand the materials available for this dynamic interphase, provide an insightful understanding of the enhanced charge transfer in the electrolyte, and realize the combination of dynamic interphase and enhanced kinetics for all‐climate performance.
