## Description

- description: Lithium-air battery (LAB) provides high-energy density batteries, but
    the slow oxygen reduction reaction kinetics have virtually limited its discharge
    only under pure oxygen atmosphere with extremely low power output. Herein, to
    boost the power and energy under atmospheric oxygen, we investigated the discharge
    performance of LAB cells with low-viscosity amide-based electrolytes, N,N-dimethyl
    acetamide (DMA) and N,N-dimethyl formamide (DMF) dissolving lithium nitrate (LiNO3)
    or lithium bis(trifluloromethanesulfonyl)imide (LiTFSI). The 1/3~1/4 lower viscosity
    than the typical LAB electrolyte solvent of tetraethyleneglycol dimethylether
    (TEG) ensures fast oxygen and Li+ supply to enhance the battery power. Raman spectroscopy
    revealed less solvation in LiNO3 electrolytes, explaining the lower viscosity
    with slightly lower ion conductivity than LiTFSI electrolytes, which was more
    evident in DMF. As the result, LAB cells with DMF dissolving LiNO3 (DMF-NO3) enabled
    the highest current density discharge of 23 mA cm-2 with 2.2 mAh cm-2 capacity
    under dry-air, which demonstrates an engine like power of 2200 W kg-1 providing
    210 Wh kg-1 energy. Meanwhile, galvanostatic discharge-charge cycle test revealed
    better cyclability in DMA electrolytes due to the less solvent volatilization
    behavior. Anions mixing effectively suppressed the volatilization with reducing
    the side reactions, providing 200 Wh kg-1 energy for 14 times. Because of the
    mild oxidation condition, LAB cells extended the rechargeability under dry-air,
    rather than under pure oxygen. This work paves the way for developing “true”-LAB
    that works by air oxygen.
