Currently, there is considerable interest in developing advanced rechargeable batteries that boast efficient distribution of electricity and economic feasibility for use in large-scale energy storage systems. Rechargeable aqueous zinc batteries are promising alternatives to lithium-ion batteries in terms of rate performance, cost, and safety. In this investigation, we employ Cu (HHTP) , a two-dimensional (2D) conductive metal-organic framework (MOF) with large one-dimensional channels, as a zinc battery cathode. Owing to its unique structure, hydrated Zn ions which are inserted directly into the host structure, Cu (HHTP) , allow high diffusion rate and low interfacial resistance which enable the Cu (HHTP) cathode to follow the intercalation pseudocapacitance mechanism. Cu (HHTP) exhibits a high reversible capacity of 228 mAh g at 50 mA g . At a high current density of 4000 mA g (~18 C), 75.0% of the initial capacity is maintained after 500 cycles. These results provide key insights into high-performance, 2D conductive MOF designs for battery electrodes.
