Pre‐Corrosion of Zinc Metal Anodes for Enhanced Stability and Kinetics

Non-uniform zinc plating/stripping in aqueous zinc-ion batteries (ZIBs) often leads to dendrites formation and low Coulombic efficiency (CE), limiting their large-scale application. In this study, a pre-corroded Zn (PC-Zn) anode with 3D ridge-like structure is constructed by a facile solution etching in sodium hypophosphite (NaH
