Incompatible　electrode/electrolyte　interface　often　leads　to　dendrite　growth,　parasitic　reactions,　and　corrosion,　posing　significant　challenges　to　the　application　of　Zn　anodes.　Herein,　we　introduce　a　biomimetic　antifreeze　protein　localized　gel　electrolyte　(ALGE)　with　multifunctional　capabilities　to　address　these　issues　by　combining　electrolyte　modification　with　interface　optimization.　ALGE　modifies　the　Zn2+　solvation　structure　and　the　hydrogen-bond　network　adjacent　to　the　zinc　anode,　effectively　suppressing　hydrogen　evolution.　Additionally,　ALGE　promotes　(002)Zn　crystal　plane-dominated　deposition　by　protein-zinc　surface　interactions,　enabling　a　long-range　dendrite-free　deposition.　The　absence　of　by-products　and　inhibited　corrosion　further　highlights　the　practical　potential　of　ALGE.　Symmetric　cells　with　ALGE-modified　zinc　demonstrate　an　impressive　lifespan　of　610　h　under　a　current　density　of　10　mA　cm-2　and　a　capacity　of　10　mAh　cm-2.　The　pouch　cell　integrating　a　manganese　dioxide　cathode　and　ALGE-modified　Zn　anode　retains　75.8%　of　its　capacity　after　200　cycles　at　1　A　g-1.　This　localized　gel　electrolyte　strategy　offers　a　practical　and　scalable　approach　to　stabilizing　Zn　anodes　for　next-generation　energy　storage　systems.
