Zinc Powder Anodes for Rechargeable Aqueous Zinc-Based Batteries.

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.
