Synergistically Stabilizing Zinc Anodes by Molybdenum Dioxide Coating and Tween 80 Electrolyte Additive for High-Performance Aqueous Zinc-Ion Batteries.

ABSTRACT: Recently, aqueous zinc-ion batteries (ZIBs) have become increasingly attractive as grid-scale energy storage solutions due to their safety, low cost, and environmental friendliness. However, severe dendrite growth, self-corrosion, hydrogen evolution, and irreversible side reactions occurring at Zn anodes often cause poor cyclability of ZIBs. This work develops a synergistic strategy to stabilize the Zn anode by introducing a molybdenum dioxide coating layer on Zn (MoO₂@Zn) and Tween 80 as an electrolyte additive. Due to the redox capability and high electrical conductivity of MoO₂, the coating layer can not only homogenize the surface electric field but also accommodate the Zn²⁺ concentration field in the vicinity of the Zn anode, thereby regulating Zn
