The　existing　electrolytes　suffer　from　the　uncontrolled　Li+　deposition,　flammability,　and　limited　ionic　conductivity　problems.　The　gel-electrolyte　is　a　core　technology　for　the　lithium　metal　batteries　as　they　offer　diverse　tools　for　constructing　unique　solvent　structure　and　suppress　the　uncontrolled　growth　of　lithium　dendrites.　Here,　a　localized-anion　gel-electrolyte　with　poly(ethyl　acrylate/acrylic　acid　lithium)　is　reported　to　achieve　a　dendrite-free　lithium　deposition　with　the　stable　solid-electrolyte　interphase.　The　flame-retardant　triethyl　phosphate　are　engaged　in　gel-electrolyte　as　a　plasticizer　with　a　solution　casting　method,　which　improves　the　safety　of　Li　metal　batteries.　The　TFSI-　is　localized　by　anionphilic　-COOLi　in　the　vicinity　of　polymers,　which　maintains　the　uniform　lithium　flux　and　suppresses　the　deposition　to　achieve　the　smooth　lithium　growth.　The　lithiophilic　-COOR　group　homogenized　the　Li+　flow　at　the　electrode/electrolyte　interface　and　alleviated　the　local　lithium-ion　flow.　The　LFP//Li　cells　assembled　with　the　gel-electrolyte　can　still　maintain　a　coulombic　efficiency　of　99%　and　capacity　retention　of　96%　after　320　cycles　at　1　C.　And　the　NCM811//Li　cells　assembled　with　the　gel-electrolyte　can　maintain　about　90%　coulombic　efficiency　and　88%　capacity　retention　after　120　cycles　at　0.5　C.　In　summary,　this　work　provides　an　effective　strategy　for　the　application　of　next-generation　high-safety　lithium　metal　batteries.
