摘要
锂-空气电池是目前已知具有最高能量密度的二次电池,有望成为未来电动汽车的动力电源。由于其能量密度高、环境友好以及成本较低,成为广大科研工作者研究的热点,在过去二十年间与之有关的研究已经在反应机理、电极结构、催化剂及电解液等各方面都取得了很大进展,但受诸多因素限制,其实用化仍然任重道远。本文总结了近几年来非水体系锂-空气电池在反应机理、正极材料、催化剂、电解液以及锂负极等方面的最新研究进展,并在此基础上展望其未来的发展方向。
As a secondary battery, the Li-air battery has the highest theoretical specific energy and has been considered as one of the most promising power sources for electric vehicles. The Li-air battery based on organic electrolyte has become a topic of interest owing to its excellent theoretical energy density, environmental friendliness and low cost. During the past 20 years, much progress has been made in the development of the reaction mechanism, cathode structure, catalyst and electrolyte materials. But there are still many obstacles to overcome before its practical applications. In this paper, we review some of the latest progress in the research on the reaction mechanism, cathode materials, catalysts, electrolytes, as well as the lithium anode. Future research and development prospects are also discussed.
