As　people　possess　more　safety　conscious,　the　issue　of　electrolytes　is　attracting　concern.　The　gel　polymer　electrolyte　offers　high　ionic　conductivity,　wettability,　and　good　interfacial　contact,　effectively　reducing　electrolyte　leakage　and　improving　battery　safety.　This　study　presents　a　novel　gel　polymer　electrolyte　that　has　been　investigated　for　its　excellent　physical　and　electrochemical　properties.　The　electrospinning　film　possesses　a　thin　and　flat　surface　with　a　thickness　of　only　40　±　5 μm　and　particle　size　of　around　300–400 nm.　This　creates　an　ion-conductive　dual-channels　that　optimize　the　migration　of　lithium　ions　and　ensure　good　contact　and　interfacial　stability.　In　addition,　the　electrochemical　stability　window　ranges　from　0　~　6.1 V　(vs.　Li+/Li),　which　can　be　applied　to　most　high-voltage　cathode　materials　on　the　market.　The　NCM811//Li　cell　constructed　with　gel　polymer　electrolyte　exhibited　a　first　discharge　capacity　of　202.9 mAh　g−1　at　0.5C　and　still　maintain　a　discharge　capacity　of　117.5 mAh　g−1　after　300 cycles,　as　well　as　a　capacity　retention　rate　of　57.9%.　This　strategy　provides　a　new　idea　for　the　next　generation　of　high-performance　lithium　metal　batteries.　©　2023,　The　Author(s),　under　exclusive　licence　to　Springer-Verlag　GmbH　Germany,　part　of　Springer　Nature.
