A new promising Ni-MOF superstructure for high-performance supercapacitors

A new layered structural Ni-MOF nanosheet has been successfully synthesized and used for the first time as an electrode for a supercapacitor and a flexible all-solid-state asymmetric supercapacitor, exhibiting capacitances of 1518.8 F g−1 at 1 A g−1 and 244 mF cm−2 at 0.5 mA cm−2, respectively.
