The　uncontrolled　dendritic　growth　and　severe　side　reactions　significantly　constrain　zinc-ion　batteries＇　further　application.　This　study　presents　a　novel　micellar　gel　electrolyte,　innovatively　designed　through　hydrophobic　association.　The　micellar　gel　electrolyte　harmonizes　macroscopic　and　microscopic　properties　through　a　rational　hierarchical　design.　At　the　macroscopic　level,　the　hydrophilic　domains　as　water-absorbing　nets　and　the　hydrophobic　domains　as　pillars　are　intricately　interwoven.　On　the　microscopic　scale,　the　copolymerization　resulted　in　a　microphase-separated　architecture,　with　hydrophilic　and　hydrophobic　domains　establishing　distinct　micro-regions　within　the　gel　matrix.　The　hydrophilic　domains　contribute　to　the　stabilization　of　the　hydrogen　bond　network　through　amide　groups,　while　the　abundant　carbonyl　groups　optimize　the　solvation　structure　and　migration　pathways　of　Zn2+.　The　hydrophobic　domains　provide　a　robust　supporting　framework　while　simultaneously　reducing　H2O　activity　and　thereby　minimizing　parasitic　reactions.　Thus,　the　enhanced　interfacial　stability　forms　a　robust　and　flexible　barrier　against　dendrite　formation.　The　rational　hierarchical　gel　composition　and　cross-linked　network　effectively　direct　Zn　deposition　preferentially　along　the　(002)　plane,　ensuring　a　uniform　and　stable　interface.　The　assembled　Zn‖MnO2　batteries　show　80%　capacity　retention　after　1200　cycles　at　1C.　©　2025　The　Royal　Society　of　Chemistry.
