## Description

- description: Although lithium–oxygen batteries (LOBs) hold the promise of high gravimetric
    energy density, this potential is hindered by high charging voltages. To ensure
    that the charging voltage remains low, it is crucial to generate discharge products
    that can be easily decomposed during the successive charging process. In this
    study, we discovered that the use of amide-based electrolyte solvents containing
    a fluorinated moiety can notably establish a sustained voltage plateau at low-charging
    voltages at around 3.5 V. This occurs under conditions that can verify the feasibility
    of achieving a benchmark energy density value of 500 Wh kg–1. Notably, the achievement
    of the low-voltage plateau was accomplished solely by relying on the intrinsic
    properties of the electrolyte solvent. Indeed, synchrotron X-ray diffraction measurements
    have shown that the use of fluorine-containing amide-based electrolyte solvents
    results in the formation of highly decomposable discharge products, such as amorphous
    and Li-deficient lithium peroxides.
