Rechargeable alkali metaleair batteries are considered as the most promising candidate for the power source of electric vehicles (EVs) due to
their high energy density. However, the practical application of metaleair batteries is still challenging. In the past decade, many strategies have
been purposed and explored, which promoted the development of metaleair batteries. The reaction mechanisms have been gradually clarified
and catalysts have been rationally designed for air cathodes. In this review, we summarize the recent development of alkali metaleair batteries
from four parts: metal anodes, electrolytes, air cathodes and reactant gases, wherein we highlight the important achievement in this filed. Finally
problems and prospective are discussed towards the future development of alkali metaleair batteries.
