## Description

- description: Since the use of high-energy-density batteries continues to expand
    in large-scale applications, guaranteeing their safety is attracting increasing
    attention from the public sector and scientific communities. Considerable research
    efforts have been dedicated to identifying safer alternatives to the traditional
    electrolytes based on cyclic carbonate solvents, which represent the most flammable
    battery components. Nevertheless, developing functional electrolytes that may
    provide high safety and uncompromised electrochemical performance remains challenging.
    In this study, a multifunctional nonflammable solvent with improved storage stability,
    viz., 2-(N,N-dimethylamino)-1,3,2-dioxaphospholane 2-oxide (DMAP), is synthesized.
    The DMAP-based electrolytes enable the formation of a stable passivation film
    with high electrochemical and thermal stabilities and the suppression of exothermic
    reactions, resulting in the high reversibility of graphite anodes along with improved
    battery safety. Strategic optimization of the molecular structures of cyclic phosphoramidates
    should be a promising approach toward preparing highly safe batteries with high
    energy densities.
