## Description

- description: 'Lithium-ion battery (LIB) is now widely used in the world. However,
    its unsatisfactory fast-charging performance is limiting its applications. The
    fast-charging capability of LIB is highly affected by the surface composition
    of graphite electrode, which can be modified through electrolyte design. Herein
    we demonstrate that the combination of lithium bis(fluorosulfonyl) imide (LiFSI)
    salt with methyl acetate (MA) additive in carbonate electrolyte enables fast-charging
    Li-ion battery. Results from X-ray photoelectron spectroscopy and transmission
    electron microscopy indicate that the LiFSI-based electrolyte with MA forms a
    stable and less-resistive solid electrolyte interphase on graphite anode compared
    to electrolyte with LiPF6, facilitating the transport of Li-ion and achieving
    a superior fast-charging performance with a capacity of 230 mAh g-1 at 2 C. An
    electrolyte swapping experiment also indicates that the LiFSI salt forms a more
    stable SEI on graphite than LiPF6. This work provides a conducive electrolyte
    design for fast charging Li-ion battery with graphite anode. '
