The　safety　of　energy　storage　equipment　has　always　been　a　stumbling　block　to　the　development　of　battery,　and　sodium　ion　battery　is　no　exception.　However,　as　an　ultimate　solution,　the　use　of　non-flammable　electrolyte　is　susceptible　to　the　side　effects,　and　its　poor　compatibility　with　electrode,　causing　failure　of　batteries.　Here,　we　report　a　non-flammable　electrolyte　design　to　achieve　high-performance　sodium　ion　battery,　which　resolves　the　dilemma　via　regulating　the　solvation　structure　of　electrolyte　by　hydrogen　bonds　and　optimizing　the　electrode-electrolyte　interphase.　The　reported　non-flammable　electrolyte　allows　stable　charge-discharge　cycling　of　both　sodium　vanadium　phosphate@hard　carbon　and　Prussian　blue@hard　carbon　full　pouch　cell　for　more　than　120　cycles　with　a　capacity　retention　of　＞85　%　and　high　cycling　Coulombic　efficiency　(99.7　%).
