## Description

- description: Dual-ion batteries (DIBs), well-known for the high-rate capability
    of the graphite cathode, urgently need a suitable anode material to realize their
    high power density in practical applications. In that respect, Li4Ti5O12 (LTO),
    which can be cycled at high rates for thousands of cycles, can be a good candidate.
    However, a facile method to stabilize the graphite||LTO full cells is necessary.
    Herein, we introduce LiDFOB additive into the electrolyte of graphite||LTO cells,
    which drastically improves the cycling performance and reduces self-discharge
    of the DIBs. Specifically, by adding 1.0 wt.% LiDFOB to 2M LiPF6 in fluorinated
    ethyl methyl carbonate, graphite||LTO DIBs can maintain stable charge-discharge
    for over 8000 cycles at 20 C. Characterizations indicate that LiDFOB forms a robust
    LiF-rich solid electrolyte interphase (SEI) on the LTO anode to suppress side
    reactions such as electrolyte decomposition and gas generation.
