“…Corrosion, hydrogen evolution, and passivation are closely related to the high activity of free H 2 O on the anode surface. Reasonable regulation of the electrolyte is an effective strategy to inhibit the corrosion of Zn powder anodes and realize dendrite-free Zn deposition/stripping. − Currently, most studies on Zn powder anodes have focused on neutral/weakly acidic and alkaline electrolytes represented by ZnSO 4 and KOH. − However, there are very few studies on Zn powder anodes from the perspective of optimizing the electrolyte.…”

Aqueous zinc metal batteries (ZMBs) have attracted much attention in the field of grid-scale energy storage due to their high safety, low cost, and abundant resources. Zn powders exhibit the unique advantages of high specific surface area, mature scaled-up manufacturing ability, and structural tunability, which can meet the large-scale energy storage devices, and even the special-shaped devices. However, Zn powder-based anodes are at an early stage and far from the practical industrial application. With the pursuit of comprehensive electrochemical performances of Zn powder-based anodes, this review focus on the advances, issues, and optimized strategies, which are discussed systematically from the previous reports of Zn powder-based anodes. Meanwhile, we also added many supplementary discussions of some important strategies in relevant content but not yet reported. Finally, future prospects toward high performance and practicability of Zn powder-based anodes are proposed, which will provide scientific guidance for the practical application of ZMBs.

The cost‐effectiveness and environmental benefits of aqueous zinc‐ion batteries (ZIBs) have attracted considerable attention. However, practical applications are hindered by side processes including dendritic growth and hydrogen evolution corrosion. Herein, gallium ions (Ga3+) have been chosen as a multifunctional electrolyte additive to improve the reversibility of zinc‐ion batteries (ZIBs). Remarkably, Ga3+ ions adhere to the anode surface, establishing a dynamic electrostatic shielding layer that modulates Zn2+ deposition and prevents side reactions. Typically, Ga3+ ions preferentially adsorb onto the (002) and (110) planes of Zn, facilitating preferential deposition on the (100) plane, resulting in a dendrites‐free zinc anode. Consequently, the Zn||Zn symmetrical cell with Ga3+‐modified electrolyte demonstrates a prolonged lifespan of 4000 h, while the Zn||Ti asymmetric cell exhibits an impressive coulombic efficiency of 99.12% for zinc stripping and plating at 2 mA cm−2. Additionally, the Zn||VO2 cell maintains high capacity retention after 1500 cycles at 5 A g−1. This work presents Ga3+ ions as an electrolyte additive, facilitating the development of a durable dynamic electrostatic shielding effect and preferential (100) plane electroplating, ensuring zinc deposition free from dendrite formation. Such discoveries form a basis for future investigations into novel materials to propel advancements in metal battery technology.
