摘　　要：锌-空气电池具有高的理论能量密度(1086W?h/kg)、高安全性和低成本等优点,在电动汽车和便携式电子设备等应用中有望成为储能设备的候选,因此受到了广泛关注。锌阳极作为锌-空气电池的核心部位,目前面临诸多挑战:如枝晶生长、形变、钝化、析氢腐蚀等,限制了二次锌-空气电池的进一步发展和商业化,如何解决锌阳极存在的这些问题成为发展锌-空气电池的研究热点。当前,发展锌-空气电池的关键是开发设计具有良好可逆性和长循环寿命的锌阳极材料,研究重点主要在于阳极添加剂、合金化、包覆及混合电池等。本文主要综述了最近几年关于锌基电池锌阳极研究的一些突破和最新进展,这些信息可应用于二次锌-空气电池。Zinc-air battery has attracted widespread attention due to the high theoretical energy,excellent safety and low cost,which is hopeful to be a candidate for energy storage devices in applications like electric vehicles and portable electronic devices.Zinc anode,as the key part of zinc-air battery,has many disadvantages,such as dendrite growth,shape change,passivation and hydrogen evolution etc,which limits the further development and commercialization of secondary zinc-air battery.Thus,how to solve above problems existing in zinc anode has become an research focus of zinc-air battery.The key to develop zinc-air battery includes the design and preparation of zinc anode materials with outstanding reversibility and long cycle life,which mainly concentrates on the additives,alloying,coating of zinc anode and hybrid battery.In this context,some new findings and the latest progress on the anode of zinc-based battery in recent years are introduced,which can be applied to secondary zinc-air battery.
