Advanced electrode design is critical for the rapid development of flexible energy storage devices (ESD) in the emerging field of flexible electronics. Metal-organic frameworks ((MOFs) for lithium storage have attracted considerable attention. However, one of the main obstacles is their poor electronic conductivity, which restricts their cycling stability under redox conditions. Herein, we report a facile synthesis route to fabricate Ni(BDC-NH2)/reduced graphene oxide (rGO) composites employing the solvothermal method. Ni(BDC-NH2) MOFs exhibited a unique laminar and porous morphology, which helps with Li-ion diffusion, and thus enables faster electrode activation and capacitive controlled electrochemical activity. When freestanding Ni(BDC-NH2)/reduced graphene oxide (rGO) composite electrode was prepared via simple vacuum filtration. As anode material for lithium-ion batteries. It delivered a reversible capacity of 813 mAh g−1 at a current density of 200 mA g−1 after 100 cycles. More importantly, it also shows an excellent rate of performance compared to Ni(BDC)/rGO MOFs. The better electrochemical performance of Ni(BDC-NH2)/rGO is attributed to the unique chain network formed by the synergistic effect of multi-coordination of carboxylic oxygen and amino nitrogen with high theoretical capacities and rGO with high electrical conductivity.
