Low‐Cost Multi‐Function Electrolyte Additive Enabling Highly Stable Interfacial Chemical Environment for Highly Reversible Aqueous Zinc Ion Batteries

Abstract The practicality of aqueous zinc ion batteries (AZIBs) for large‐scale energy storage is hindered by challenges associated with zinc anodes. In this study, a low‐cost and multi‐function electrolyte additive, cetyltrimethyl ammonium bromide (CTAB), is presented to address these issues. CTAB adsorbs onto the zinc anode surface, regulating Zn 2+ deposition orientation and inhibiting dendrite formation. It also modifies the solvation structure of Zn 2+ to reduce water reactivity and minimize side reactions. Additionally, CTAB optimizes key physicochemical parameters of the electrolyte, enhancing the stability of the electrode/electrolyte interface and promoting reversibility in AZIBs. Theoretical…
