Rechargeable　aqueous　zinc-ion　batteries　(RAZIBs)　are　attractive　due　to　their　affordability,　safety,　and　eco-friendliness.　However,　their　potential　is　limited　by　the　lack　of　high-capacity　cathodes　and　compatible　electrolytes　needed　for　reliable　performance.　Herein,　we　have　presented　a　compatibility　strategy　for　the　development　of　a　durable　and　long-lasting　RAZIBs.　The　covalent　organic　frameworks　(COFs)　based　on　anthraquinone　(DAAQ-COF)　is　created　and　utilized　as　the　cathode,　with　zinc　metal　serving　as　the　anode.　The　electrolyte　is　made　up　of　an　aqueous　solution　containing　zinc　salts　at　various　concentrations.　The　COF　cathode　has　been　designed　to　be　endowed　with　a　rich　array　of　redox-active　groups,　enhancing　its　electrochemical　properties.　Meanwhile,　the　electrolyte　is　formulated　using　triflate　anions,　which　have　exhibited　superiority　over　sulfate　anions.　This　strategy　lead　to　the　development　of　an　optimized　COF　cathode　with　fast　charging　capability,　high　Coulombic　efficiency　(nearly　100　%)　and　long-term　cyclability　(retention　rate　of　nearly　100　%　at　1　A　g−1　after　10000　cycles).　Moreover,　through　experimental　analysis,　a　co-insertion　mechanism　involving　Zn2+　and　H+　in　this　cathode　is　discovered　for　the　first　time.　These　findings　represent　a　promising　path　for　the　advancement　of　organic　cathode　materials　in　high-performance　and　sustainable　RAZIBs.　©　2024　Wiley-VCH　GmbH.
