Creation of an Artificial Layer for Boosting Zn2+ Mass Transfer and Anode Stability in Aqueous Zinc Metal Batteries

Natural extract, curcumin, was employed as the protective layer to improve the zinc anode stability. The curcumin-based layer balanced the efficient thickness, robust adhesion, and facilitated Zn 2+ transportation. The desolvation mechanism with a metal ion chelating agent aside was clearly elucidated.
