Organic Cations Texture Zinc Metal Anodes for Deep Cycling Aqueous Zinc Batteries

Abstract Manipulating the crystallographic orientation of zinc (Zn) metal to expose more (002) planes is promising to stabilize Zn anodes in aqueous electrolytes. However, there remain challenges involving the non‐epitaxial electrodeposition of highly (002) textured Zn metal and the maintenance of (002) texture under deep cycling conditions. Herein, a novel organic imidazolium cations‐assisted non‐epitaxial electrodeposition strategy to texture electrodeposited Zn metals is developed. Taking the 1‐butyl‐3‐methylimidazolium cation (Bmim + ) as a paradigm additive, the as‐prepared Zn film ((002)‐Zn) manifests a compact structure and a highly (002) texture without containing (100) signal.
