Gel　electrolytes　are　gaining　attention　for　rechargeable　Zn-ion　batteries　because　of　their　high　safety,　high　flexibility,　and　excellent　comprehensive　electrochemical　performances.　However,　current　gel　electrolytes　still　perform　at　mediocre　levels　due　to　incomplete　Zn　salts　dissociation　and　side　reactions.　Herein,　an　electrostatic-induced　dual-salt　strategy　is　proposed　to　upgrade　gel　electrolytes　to　tackle　intrinsic　issues　of　Zn　metal　anodes.　The　competitive　coordination　mechanism　driven　by　electrostatic　repulsion　and　steric　hindrance　of　dual　anions　promotes　zinc　salt　dissociation　at　low　lithium　salt　addition　levels,　improving　ion　transport　and　mechanical　properties　of　gel　electrolytes.　Li+　ions　and　gel　components　coordinate　with　H2O,　reducing　active　H2O　molecules　and　inhibiting　associated　side　reactions.　The　dual-salt　gel　electrolyte　enables　excellent　reversibility　of　Zn　anodes　at　both　room　and　low　temperatures.　Zn||Polyaniline　cells　using　the　dual-salt　gel　electrolyte　exhibit　a　high　discharge　capacity　of　180 mAh g−1　and　long-term　cycling　stability　over　180　cycles　at　−20 °C.　The　dual-salt　strategy　offers　a　cost-effective　approach　to　improving　gel　electrolytes　for　high-performance　flexible　Zn-ion　batteries.　©　2024　Wiley-VCH　GmbH.
