## Description

- description: The poor oxidation stability of ether-based solvents has long been
    a major challenge limiting their practical application. To enhance the oxidative
    stability of ether-based electrolytes, the physicochemical properties of various
    glycol dimethyl ethers are screened, and diglyme (G2) is selected as the sole
    solvent for the electrolyte. Lithium bis(fluorosulfonyl)imide (LiFSI), a highly
    dissociative salt, is used as the primary salt, while lithium nitrate (LiNO3)
    and lithium difluorophosphate (LiDFP), which have small ionic sizes and strong
    binding energies, are added as secondary salts. The resulting electrolyte can
    modulate the electric double layer (EDL) structure by NO3− and DFP− on the cathode
    side, leading to an increased Li+ concentration that is originally repelled by
    the cathode. Additionally, the oxidation stability of the electrolyte is improved
    and the formed electrode-electrolyte interphase (EEI) is more uniform and stable,
    thereby enhancing the electrochemical performance of the cells. As a result, cells
    assembled with a total of 1M ternary lithium salt electrolyte in G2 solvent can
    operate at high voltage of 4.4 V. The Li||NCM811 cells maintain 80.2% capacity
    retention after 270 cycles at room temperature, with an average Coulombic efficiency
    of 99.5%, and exhibit 88.4% capacity retention after 200 cycles at −30 °C.
