In this work, porous NiMn 2 O 4 nanosheets with large surface areas are successfully grown by a hydrothermal method and examined as electrodes for supe rcapac itors. Resu lts h ave sho wn th at the supercapacitor based on NiMn 2 O 4 electrodes exhibits the highest specific capacitance of 1321.6 F g −1 at a scan rate of 2 A g −1 , much higher than those of other supercapacitors made of metal oxides and composites. The NiMn 2 O 4 supercapacitor also shows a good cycling behavior, only 6.5 % capacitance decay after 1500 cycles. The NiMn 2 O 4 nanosheets possess a robust mechanical adhesion to Ni foam, which has been demonstrated by an ultrasonication test.

We report a new environmentally-friendly synthetic strategy for large-scale preparation of 16 nm-ultrathin NiCo based layered double hydroxides (LDH). The Ni50Co50-LDH electrode exhibited excellent specific capacitance of 1537 F g−1 at 0.5 A g−1 and 1181 F g−1 even at current density as high as 10 A g−1, which 50% cobalt doped enhances the electrical conductivity and porous and ultrathin structure is helpful with electrolyte diffusion to improve the material utilization. An asymmetric ultracapacitor was assembled with the N-doped graphitic ordered mesoporous carbon as negative electrode and the NiCo LDH as positive electrode. The device achieves a high energy density of 33.7 Wh kg−1 (at power density of 551 W kg−1) with a 1.5 V operating voltage.

“…Figure e depicts a comparison of its calculated volumetric capacitances based on the discharge curves with the values of recently reported SC anodes. Significantly, the as‐prepared WON electrode yielded a remarkable volumetric capacitance of 4.95 F cm −3 at 12.5 mA cm −3 (4.76 F cm −3 at 10 mV s −1 ), which is considerably higher than that of most reported anodes . When the current density reached 500 mA cm −3 , a high volumetric capacitance of 3.35 mF cm −3 was still achieved, which means more than 67% of its initial capacitance could be retained.…”
