Recent Progress in Electrolyte Additives for Highly Reversible Zinc Anodes in Aqueous Zinc Batteries

Aqueous zinc batteries (AZBs) are one of the most promising large-scale energy storage devices by virtue their high specific capacity, degree safety, non-toxicity, and significant economic benefits. However, Zn anodes in aqueous electrolyte suffer from dendrites side reactions, which lead to a low coulombic efficiency short life cycle cell. Since electrolytes play key role plating/stripping process, versatile strategies have been developed for designing an handle these issues. Among strategies, additives considered be practical application because advantages cost simplicity. Moreover, resulting can maximally preserve merits electrolyte. The availability effectiveness demonstrated tens research works. Up now, it has essential timely systematically overview progress mild acidic/neutral electrolytes. These classified as metal ion additives, surfactant SEI film-forming complexing according functions mechanisms. For each category functional mechanisms, well latest developments, comprehensively elaborated. Finally, some perspectives into future development advanced AZBs presented.
