Elucidating synergistic mechanisms of an anion–cation electrolyte additive for ultra-stable zinc metal anodes

Abstract

The present work presents a multi-functional 0.2 M NaI electrolyte additive to suppress Zn dendrites and water-induced parasitic reactions in aqueous Zn metal batteries, featuring an astonishing Zn deposition/stripping cyclability of 8632 h.
