Flexible wearable batteries are widely used in smartwatches,foldable phones,and fitness trackers due to their thinness and small size.Zinc-based batteries have the advantages of low cost,high safety,and eco-friendliness,which are considered to be the best alternative to flexible lithium-ion batteries(LIBs).Therefore,wearable flexible zinc-ion batteries(FZIBs)have attracted considerable interest as a promising energy storage device.Electrospun nanofibers(ESNFs)have great potential for application in wearable FZIBs due to their low density,high porosity,large specific surface area,and flexibility.Moreover,elec-trospinning technology can achieve the versatility of nanofibers through structural design and incorpo-ration of other multifunctional materials.This paper reviews a wide range of applications of electrospinning in FZIBs,mainly in terms of cathode,anode,separator,polymer electrolyte,and all-in-one flexible batteries.Firstly,the electrospinning device,principles,and influencing parameters are briefly described,showing its positive impact on FZIBs.Subsequently,the energy storage principles and electrode configurations of FZIBs are described,and some of the common problems of the batteries are illustrated,including zinc anode dendrite growth,corrosion,cathode structure collapse,and poor electrical conductivity.This is followed by a comprehensive overview of research progress on the individ-ual components of FZIBs(cathode,anode,separator,and polymer electrolyte)from the perspective of electrostatically spun fiber materials and an in-depth study of all-in-one flexible batteries.Finally,the challenges and future development of FZIBs are individually concluded and look forward.We hope that this work will provide new ideas and avenues for the development of advanced energy technologies and smart wearable systems.
