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.
