Non-solvating additives regulate zinc deposition through anion-gated Stern-layer competition.

ABSTRACT: While additive-induced modulation of solvation structure has emerged as an effective strategy to enhance the performance of aqueous zinc-ion batteries, the electrochemical mechanisms by which non-solvation additives interact with ion species within the electric double layer and their subsequent impact on solid electrolyte interphase evolution remain poorly understood. Here, we propose an anion-released interfacial engineering strategy that leverages the competitive spatial distribution between surface-affinitive anions and cationic regulators within the Stern layer. This competition governs additive accessibility to the interface and enables the construction of a robust, inorganic-organic hybrid interface. Combined with in situ spectra and theoretical simulations, we decouple the key kinet
