摘　　要：锌–空气电池凭借其高能量密度、电极材料资源丰富、生产成本低、储存寿命长、绿色环保无污染等优点而被广泛研究,但由于锌阳极在循环过程中存在锌枝晶生长、钝化等问题,导致锌–空气电池的实际能量密度低于理论容量密度,严重制约了其发展与应用。本文根据锌–空气电池的锌阳极工作原理和钝化机理,从电解液优化、锌阳极结构设计和表面改性等方面分析提出解决锌阳极钝化的措施,并提出了关于这些问题未来的研究方向,最后对锌–空气电池的未来发展做出展望。Zinc-air battery has been widely studied due to its advantages of high energy density,abundant electrode material resources,low production cost,long storage life,environmental protection,no pollution,etc.However,in the process of charging and discharging of zinc electrode,the resulted problems including dendrite growth,passivation,hydrogen evolution and corrosion greatly reduce the cycle stability and service life of zinc ion battery.It becomes an important reason for the difference between theoretical energy density and actual energy density of zinc-air battery,and seriously restricts its commercial development process.According to the working principle and passivation mechanism of zinc anode of zinc-air battery,the measures to solve the passivation of zinc anode were analyzed from the aspects of electrolyte optimization,structure design and surface modification of zinc anode.Furthermore,the future research direction of these problems were put forward.Finally,the future development of zinc-air battery was prospected.
