ABSTRACT: Li-air batteries have received much attention in the past several years because of their large
theoretical specific energy density, stable output voltage, cost-effective, energy-efficient and pollution
free, and have broad application prospects. If it is successfully developed, the battery could
be an excellent energy storage device for renewable energy sources such as wind, solar, and tidal
energy, which brings a prospect for human to solve the problem of environment pollution and
energy crisis. But the electrolyte is a crucial component of Li-air battery and the electrochemical
performance of the battery is determined by electrolyte to a great extent. Due to the react violently
between lithium and water, it is not practical for Li-air battery to use directly an aqueous electrolyte
unless the anode can be protected from degradation. In this review, we presented the latest
research progress on the non-aqueous electrolyte, i.e. organic electrolyte, ionic liquid and solid
electrolyte. We elaborated the influence of solvents, and possible additives, and/or their combination
Li-air battery’s performance. Finally, we provided insights into the prospect of non-aqueous
electrolyte for Li-air battery.
