Research Progress of Lithium-air Battery

With the increasing demand for high-performance battery by electric vehicle and the energy storage of power grid, the lithium-air battery with ultra-high specific energy has received more and more attention. To develop safe and practical lithium-air battery with good cycle performance, researchers have done plenty of exploratory work on the corresponding cathode materials, electrolyte, catalyst and waterproof oxygen permeation membrane, etc. Among all the work, finding stable electrolyte and minimizing discharge products’ passivation are the most critical issues. In this paper, based on the aprotic electrolyte architecture, the latest researches on the mentioned respects of the lithium-air battery are reviewed. In addition, the general development of other three architectures is introduced. At last, the future challenges in development of lithium-air battery are proposed.
