Suppressing Continuous Zinc Epitaxial Growth in Rechargeable Zinc–Air Batteries via Plating–Stripping Balance of Ultra-Reversible Anodes
The formation of zinc dendrites under high current density charging/discharging is one of the key issues hindering the use of zinc-air batteries as fast-charging/discharging power batteries. In this study, a Ni foam-loaded Zn anode was strategically designed and integrated with a corrosion-resistant Ni-doped Co<sub>3</sub>O<sub>4</sub> cathode catalyst to build a Zn-NF<sub>60</sub>|CoNiO cell. The cell achieves an unprecedented operating cycle life of over 160 h at 50 mA cm<sup>-2</sup>, an 8-fold extension over Zn|CoNiO. This study reveals the positive effects of the porous electrode strategy in optimizing the zinc plating and stripping process, providing new insights on addressing the issue of the continuous Zn anode epitaxial growth under high current density.
