摘　　要：近年来,人们越来越关注柔性可穿戴电子设备。柔性锌-空气电池由于有较高的理论能量密度以及对像人体一样不均匀表面的适应能力,有望成为下一代电子产品的电源。在柔性锌-空气电池研究领域,人们已经取得了较好的研究进展,各种柔性锌-空气电池的制备方法已被报道。本文阐述了近年来柔性锌-空气电池的主要成就以及面临的困难,特别是关注凝胶电解质、金属阳极以及柔性空气阴极对柔性锌-空气电池电化学性能的影响,最后讨论了柔性锌-空气电池面临的主要挑战与发展前景。In recent years,flexible and wearable electronic devices have attracted increasing research,industrial,and consumer attention.In particular,flexible zinc-air batteries(ZABs)are expected to become a promising power supply source for next-generation electronic products,especially the flexible and wearable ones,because of their high theoretical energy density,high specific capacity,high safety,and adaptability to uneven surfaces like human body.In the research field of flexible ZABs,a steady progress has been observed,and various ZAB preparation methods have been recently proposed.In this review,the main achievements and limitations of the recent research related to flexible ZABs are described.Firstly,the importance and applications of ZABs are discussed,followed by the working principle and configuration of typical ZABs.In the main text,the recent development of gel electrolytes,anodes,and cathodes is reviewed in detail.Currently,one of the most important limitations in the preparation of high-performance ZABs is the selection or preparation of a suitable gel electrolyte.A good gel electrolyte should have the ability of high-water holding capacity,high and low temperature resistance,high CO2-tolerance,excellent ionic conductivity,and good mechanical ductility.Several gel electrolytes with various functions have been developed.However,novel gel electrolytes with multifunctional properties have not been developed.In addition,interfaces between the gel electrolyte and air cathode and those between the gel electrolyte and metal anode must be investigated in detail for ZAB performance improvement.Till now,only the effects of physical compression on the electrolyte-air cathode and electrolyte-metal anode interfaces have been adopted and investigated.Moreover,the air cathode and metal anode must exhibit high flexibility to expand the application scope of ZABs as flexible power supplies.Carbon cloth has been typically used as the substrate of the air cathode;however,carbon corrosion occurs under high potential,which needs
