An amino-functionalized metal–organic framework nanosheet array as a battery-type electrode for an advanced supercapattery

Abstract

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.
