Abstract：

The　heterogeneity,　species　diversity,　and　poor　mechanical　stability　of　solid　electrolyte　interphases　(SEIs)　in　conventional　carbonate　electrolytes　result　in　the　irreversible　exhaustion　of　lithium　(Li)　and　electrolytes　during　cycling,　hindering　the　practical　applications　of　Li　metal　batteries　(LMBs).　Herein,　this　work　proposes　a　solvent-phobic　dynamic　liquid　electrolyte　interphase　(DLEI)　on　a　Li　metal　(Li–PFbTHF　(perfluoro-butyltetrahydrofuran))　surface　that　selectively　transports　salt　and　induces　salt-derived　SEI　formation.　The　solvent-phobic　DLEI　with　C–F-rich　groups　dramatically　reduces　the　side　reactions　between　Li,　carbonate　solvents,　and　humid　air,　forming　a　LiF/Li3PO4-rich　SEI.　In　situ　electrochemical　impedance　spectroscopy　and　Ab-initio　molecular　dynamics　demonstrate　that　DLEI　effectively　stabilizes　the　interface　between　Li　metal　and　the　carbonate　electrolyte.　Specifically,　the　LiFePO4||Li–PFbTHF　cells　deliver　80.4%　capacity　retention　after　1000　cycles　at　1.0　C,　excellent　rate　capacity　(108.2　mAh　g−1　at　5.0　C),　and　90.2%　capacity　retention　after　550　cycles　at　1.0　C　in　full-cells　(negative/positive　(N/P)　ratio　of　8)　with　high　LiFePO4　loadings　(15.6 mg　cm−2)　in　carbonate　electrolyte.　In　addition,　the　0.55　Ah　pouch　cell　of　252.0 Wh　kg−1　delivers　stable　cycling.　Hence,　this　study　provides　an　effective　strategy　for　controlling　salt-derived　SEI　to　improve　the　cycling　performances　of　carbonate-based　LMBs.　©　2024　Wiley-VCH　GmbH.
