Excellent results included a specific capacitance of 954 F g -1 at a current density of 1 A g -1 and 80% efficiency at 5 A g -1 of current density. The Ni-MOF/rGO-300/activated carbon asymmetric super capacitor produced positive electrochemical results, according to the scientists . Jie Sun et al. produced three NiCo-MOF morphologies (nano spheres, hollow spheres and rhombus sheets) by changing the solvent alone. All three samples have electrochemical characteristics and were sarcastic. When compared, it can be seen that the most recent sample had a specific capacitance of 1126.7 F g -1 at 0.5 Ag -1 current density and that its efficiency remained at 93% at 10 Ag -1 current density after 3000 cycles . NiCo-MOF bimetallic hetero structure nanosheets were mentioned as a good candidate for making SC electrodes last year. The material as created also finds numerous uses in sensors, batteries, catalysts and fuel cells. It has an energy density of 76.3 Whg -1 and a super capacitor capacity of 244 Fg -1 . The nanocomposite also exhibits a high specific capacitance of 4077.3 F g -1 at a current density of 2.5 A g -1 .
