Anion Induced Electric Double Layer Compression and Desolvation Optimization Enable Long Life Zinc Anodes under High-Rate.

ABSTRACT: Aqueous zinc-ion batteries (AZIBs) represent a promising next-generation energy storage solution. However, AZIBs suffer from severe dendrite growth caused by rampant Zn²⁺ 2D diffusion and sluggish desolvation kinetics, thus exhibiting extremely short cycle life under high-rate conditions. Here in, a novel additive DL-O-Methylserine (MeSer) is reported, which effectively optimizes Zn²⁺ diffusion behavior and facilitates the desolvation process. Experimental and computational results reveal that MeSer^- adsorption on the electrode surface compresses the electric double layer (EDL), thereby reducing repulsive forces within it. The decrease in repulsion further enhances Zn²⁺ 3D diffusion leading to uniform deposition. Furthermore, MeSer^- in
