摘　　要：锂空气电池具有高能量密度和低还原电位,是一种绿色储能电池,其应用范围广泛。由于传统的有机电解液存在可燃、易分解、易形成锂枝晶以及易形成阻碍O_(2)扩散的钝化层等问题,所以需开发固态电解质来提高锂空气电池的各项性能。该文介绍了锂空气电池的构建及工作机制,综述了经典全固态锂空气电池的调控策略,包括正极调控策略和电解质调控策略,同时对正极/电解质一体化设计策略进行了概述,最后对锂空气电池的固体电解质、界面修饰(即电解质与电极界面阻力的改善)和空气正极设计的优化等发展方向进行了展望。Lithium-air batteries,with high energy density and low reduction potential,are a green energy storage batteries and have a wide range of applications.Due to the problems of flammability,decomposition,formation of lithium dendrites and formation of a passivation layer that hinders diffusion of O_(2) associated with the traditional organic electrolyte,development of solid electrolytes is necessary in order to improve the performance of lithium-air batteries.Herein,the construction and working mechanism of lithium-air batteries were introduced.The regulation strategies of classic all-solid-state lithium-air battery,including cathode control strategy and electrolyte control strategy,were then summarized,while the integrated design strategy of cathode/electrolyte was also reviewed.Finally,the development direction of solid electrolytes,interface modification(improvement of electrolyte and electrode interface resistance)and the optimization on air cathode design of lithium-air batteries was discussed.
