High-Performance Zinc-Bromine Rechargeable Batteries Enabled by In-Situ Formed Solid Electrolyte Interphase.

ABSTRACT: Aqueous zinc-bromine batteries (ZBBs) are promising candidates for renewable energy storage, offering advantages over lithium-ion batteries. However, their widespread adoption is hindered by challenges such as zinc dendrite formation and water decomposition, which lead to short circuits, electrode degradation and reduced cycle life. Therefore, this study presents a facile strategy for in-situ construction of a fluorinated solid electrolyte interphase (SEI) formed via coating graphite current collectors with a lubricant hydrophobic perfluoropolyether interlayer. During the initial charging process, a fluoride-rich SEI layer forms to regulate Zn nucleation and suppress dendrite growth. This SEI promotes uniform zinc deposition and inhibits hydrogen evolution by limiting water access to the e
