Fluorinated　polymer　matrix　emerges　as　a　promising　candidate　owing　to　their　enhanced　anti-oxidation　ability,　but　their　application　is　plagued　by　the　relatively　low　ion　conduction　ability　and　the　ambiguous　ionic　conduction　mechanism　in　the　fluorinated　polymer　electrolytes　(PEs).　Herein,　a　series　of　acrylate-based　electrolytes　with　different　fluorinated　functional　units　(fluorinated-FUs)　of　poly(ethyl　methacrylate)　electrolyte　(0F　PE),　poly　(trifluoroethyl　methacrylate)　electrolyte　(3F　PE)　and　poly(hexafluorobutyl　methacrylate)　electrolyte　(6F　PE)　were　investigated.　Beneficial　from　the　long　fluorinated-FUs　in　the　side　chain,　the　6F　PE　exhibits　improved　both　ionic　conductivity　of　4.0x10(-4)　S　cm(-1)　and　Li+　transference　number　of　0.65　at　25　degrees　C,　which　are　superior　to　those　of　the　0F　PE　and　the　3F　PE.　The　enhanced　ion　conduction　mechanism　was　clarified　via　combining　the　theoretical　calculations　and　experimental　data,　where　the　integration　of　local　fluorinated-FUs　provides　additional　coordinating　sites　for　the　continuous　Li+　migration　and　regulates　the　ion　transporting　pathways.　This　work　demonstrates　that　the　regulation　of　local　fluorinated-FUs　can　provide　a　promising　strategy　for　achieving　high　performance　PEs　applied　in　solid-state　batteries.
