{ "DOI": "10.1021/acsaem.3c01163", "abstract": "<p>We synthesized and studied a redox-active quinone-basedporousorganic polymer (rPOP) and found ultralong cycle life: it is a promisingorganic cathode for aqueous zinc-ion batteries (ZIBs). It has highphysicochemical stability and enhanced intrinsic conductivity fromits fused-aromatic conjugated skeleton. rPOP's high porosityallows for efficient Zn2+ infiltration through the poresduring charging-discharging cycles and contributes to the efficientutilization of redox-active quinone units. It delivers a specificcapacity of 120 mAh g(-1) at a current density of0.1 A g(-1) with a flat and long discharge plateau,which is critically important to provide a stable voltage output.It provides ultralong cycle life at a current density of 1.0 A g(-1) for 1000 and at 2.0 A g(-1) for 30 000cycles, with initial capacity retention of 95 and 66%, respectively.The co-insertion (Zn2+ and H+) charge storagemechanism was investigated using various electrochemical measurementsand ex/in situ structural characterization techniques, and is explainedherein. These findings contribute to a better understanding of thestructure-property relationship for rPOP and open a new avenuefor new organic cathode materials for high-performance next-generationaqueous batteries.</p>", "author": [ { "family": "Buyukcakir", "given": " Onur" }, { "family": "Yuksel", "given": " Recep" }, { "family": "Begar", "given": " Ferit" }, { "family": "Erdogmus", "given": " Mustafa" }, { "family": "Arsakay", "given": " Madi" }, { "family": "Lee", "given": " Sun Hwa" }, { "family": "Kim", "given": " Sang Ouk" }, { "family": "Ruoff", "given": " Rodney S.
