Electrospinning Machine| Desolvated ion screening composite fiber interlayer enables dendrite-free anode for aqueous zinc-ion batteries 2025-08-11
With the rapid development of energy storage technology, aqueous zinc-ion batteries (AZIBs) have attracted widespread attention as a promising alternative to lithium-ion batteries due to their low cost, high safety, and environmental friendliness. However, in practical applications, zinc anodes are prone to hydrogen evolution and dendrite growth during plating/stripping, leading to side reactions, electrode surface passivation, and safety hazards. To address these issues, researchers have proposed various strategies from thermodynamic and kinetic perspectives to suppress dendrites and enhance zinc electrode stability. For example, high-concentration electrolytes can reduce water activity and inhibit dendrite growth, while artificial solid electrolyte interphase (SEI) films help improve ion transport kinetics. Additionally, the crystallographic orientation of zinc deposition significantly affects dendrite suppression, and introducing ion-regulating interlayers is considered an ideal str
