Cycle life prediction of NiCo2O4//activated carbon asymmetric supercapacitors

Carbon-Embedded Ru/NiO-CuO Cathode and rGO/α-Co3O4 Anode for Synergetic Charge Transfer for High-Performance Solid-State Asymmetric Supercapacitors

“…Hence, it is concluded that the energy storage performance of the ASC device is superior when compared to previously reported nickel, copper, and cobalt metal oxide-based Ragone plot, as shown in Figure 11 such as Zn−CoO/RGO//AC (9.64 W h kg −1 at 347 W kg −1 ), 33 Ni−Co−Cu//AC (0.69 W h kg −1 at 66.84 W kg −1 ), 76 NiCo 2 O 4 -rGO//AC (23.32 W h kg −1 at 324.9 W kg −1 ), 77 Al-QCG/NF//KOH//AC/NF (15 W h kg −1 at 763.4 W kg −1 ), 78 Co 3 O 4 -rGO//AC (38.8 W h kg −1 at 400 W kg −1 ), 79 ZCONS//AC (28.2 W h kg −1 at 332.5 W kg −1 ), 80 NiO@C//CAC (39 W h kg −1 at 450 W kg −1 ), 81 NiCo@g-C 3 N 4 //AFC (26 W h kg −1 at 750 W kg −1 ), 82 Cu 3 Se 2 //AC (30.8 W h kg −1 at 461 W kg −1 ), 83 and NiCo 2 O 4 //AC (25.02 W h kg −1 at 760 W kg −1 ). 84 Table 2 48,76−88 shows the comparison of the ASC performance of the Cs/Ru@NiO-CuO//rGO/α-Co 3 O 4 electrode with other reported electrodes in the ASC device. The electrical stability and long-term durability of the fabricated ASC device were investigated through Nyquist plot of EIS (Figure 10j) and equivalent circuit (inset of Figure 10j).…”
