Very high supercapacitance (321.8 F g 1 at 4 A g 1 ) and great cyclic stability up to 5000 cycles with 97% efficiency were revealed by electrochemical experiments. The production of various heterometallic MOFs for evaluating their electrochemical potential is made possible by the current synthesis method . Dandan Han et al. developed Co3O4@CoNi2S4 porous material that can enhance the electrochemical activities of SCs. They provided some really interesting results, such as sp. capacitances of 244.4 mA h g -1 at current densities of 1 A g -1 and an exceptional rate capability of 86% at 16 A g -1 after 1000 cycles . According to a review article by Jayesh Cherusseri et al., MOF-based electrodes for SCs are very potential options because they have excellent power and energy densities. Co3O4@Co-MOF electrochemical activities were 1020 F g -1 at 0.5 A g -1 with efficiency remaining 97% for 5000 cycles .
