An amino-functionalized metal–organic framework nanosheet array supported on nickel foam (NH₂-Co-MOF-NS/NF) was fabricated and served as a binder-free battery-type electrode, which exhibited maximum areal specific capacities of 6.7 C cm⁻² (1861 μA h cm⁻²) and 2.9 C cm⁻² (806 μA h cm⁻²) in a three-electrode device and in a supercapattery device, respectively. Moreover, the advanced supercapattery device delivered a high energy density of 0.351 mW h cm⁻² at a power density of 1.70 mW cm⁻², with superior capacity retention of 91.8% after 5000 cycles. This work can provide an efficient strategy to construct amino-functionalized 2D MOF nanosheets for energy storage and conversion.
