Exposing Zn(002) Texture with Sucralose Additive for Stable and Dendrite-Free Aqueous Zinc-Ion Batteries.

ABSTRACT: Aqueous zinc-ion batteries (AZIBs) are currently confronted with the challenge of achieving long-term cyclic stability under high current densities. This issue is primarily attributed to the excessive growth of dendrites and the occurrence of significant side reactions. Herein, sucralose (SCL), as an electrolyte additive, has been used to promote the exposure of the Zn(002) texture. The introduction of SCL can adjust the Zn²⁺ nucleation and diffusion along different crystal facets, promoting the exposure of the Zn(002) texture. By substituting water molecules in the [Zn(H₂O)₆]²⁺, SCL reconfigures the hydrogen bond network in the electrolyte, reconstructing the solvation structure and suppressing the hydrogen evolution reaction. Consequently, the
