“…The overpotential was decreased to 36 mV at a high current density of 10 mA cm −2 , and the lifespan was substantially prolonged to 900 h at 1 mA cm −2 and 0.5 mAh cm −2 . Cao et al recommended the introduction of an additive, 1-carboxymethyl-3-vinylimidazolium bromide (CAVImBr), into 2 M ZnSO 4 electrolyte, 56 which could interact with the surface of Zn-P anodes and zinc ions, suppressing hydration and associated corrosion (Figure 5b).…”

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.

“…Volume expansion, Surface corrosion, dendrite growth and hydrogen evolution reaction (HER) are the main factors affecting the practical application of Zn powder anodes (Figure 2). [33,34] Characterized by a unique spherical microstructure and a large surface area, Zn powder anodes face drastic volume changes during the cycling. [35] As a result, the Zn powder gradually loses contact with the current collector, possibly leading to detachment, and ultimately causing a short circuit in the battery.…”

“…[40] Consequently, this will result in a more pronounced corrosion of the Zn powder anode compared to the two-dimensional Zn foil, potentially leading to structural collapse even in the case of a spherical Zn powder configuration. [34,41] The generation of H 2 leads to an accumulation of hydroxide ions on the surface of the Zn powder anode, thereby facilitating the formation of an irreversible by-product known as ZnSO 4 (OH) 6 • xH 2 O (ZHS). This phenomenon subsequently contributes to an increase in internal resistance within the battery system, ultimately resulting in rapid battery failure.…”

The pursuit of alternative anode materials featuring inexpensive, efficient, and adaptable is shaping the future of rechargeable zinc‐ion batteries. The Zn powder anodes stand out among contenders due to their cost‐effectiveness, exceptional processability, and adjustability. However, their widespread use is hampered by significant challenges, including volume expansion and dendrite growth. To counter these issues, a gamut of optimization strategies for Zn powder anodes has been explored and developed. This review systematically encapsulates these research findings, offering a comprehensive understanding of various enhancement methods, such as three‐dimensional printing, in‐situ surface engineering, scalable electrostatic self‐assembly, and epoxy oligomer binding. These methodologies are discussed in detail in the context of their unique synthesis methods and underlying mechanisms. The paper concludes by outlining prospective research trajectories aimed at further optimizing the use of Zn powder anodes in aqueous zinc‐ion batteries, thereby illuminating potential avenues for future exploration and development.

Aqueous zinc metal batteries (AZMBs) have emerged as a focal point of interest in academic research and industrial strategic planning. Zinc powder (ZP) is poised to assume a prominent position in both future research and practical applications due to its high Zn utilization rate and processability. However, critical challenges need to be addressed before realizing substantial progress. Notably, severe voltage polarization and gas production of ZP electrodes stand out as the primary causes of battery failure, differing with zinc foil where short circuits caused by zinc dendrites contribute to battery failure. While numerous comprehensive reviews have offered effective strategies for zinc foil, a systematic summary of ZP electrodes is still lacking. For ZP, electrode preparation dictates the performance. This review summarizes the criteria for optimal ZP electrodes, covering electrode components, preparation methods, and technique parameters. It emphatically introduces the underlying causes and strategies of water‐related side reactions and briefly analyzes the stripping/plating behaviors of ZP electrodes. The status quo of ZP‐based batteries is then discussed in categories of ZP, current collector, conductive scaffold, binder, and electrolytes. Finally, potential avenues for future research are proposed from three aspects to enhance the focus on ZP electrodes and facilitate the practical application of AZMBs.
