Advanced Functional Materials, Год журнала: 2021, Номер 31(26)

Опубликована: Май 7, 2021

Abstract Anode‐free zinc batteries (AFZBs) are proposed as promising energy storage systems due to their high density, inherent safety, low cost, and simplified fabrication process. However, rapid capacity fading caused by the side reactions between in situ formed metal anode electrolyte hinders practical applications. To address these issues, aqueous AFZBs enabled engineering form a stable interphase designed. By introducing multifunctional fluoride (ZnF 2 ) additive into electrolyte, F‐rich interfacial layer is formed. This can not only regulate growth orientation of crystals, but also serve an inert protection against such H generation. Based on synergy effects, deposition/dissolution with reversibility (Coulombic efficiency > 99.87%) cycling performance up 600 h achieved optimized ZnF . With this life significantly improved.
