Regulating Interface Engineering by Helmholtz Plane Reconstructed Achieves Highly Reversible Zinc Metal Anodes

Abstract The rampant dendrite growth and notorious parasitic reactions significantly compromise the stability of zinc anodes in aqueous zinc metal batteries, presenting substantial for their practical applications. Herein, this work proposes a synergistic strategy that reconstructs the Helmholtz plane to precisely regulate the interface chemistry between the anode and the electrolyte. Experimental investigations and theoretical calculations demonstrate that even a small amount of pyridine oxide (PNO) additive effectively alters the coordination environment and reorganizes the solvation sheath in the Outer Helmholtz Plane (OHP). Simultaneously, PNO molecules preferentially adsorbed on the anode surface,…
