High-performance asymmetric supercapacitor based on CdCO(3)/CdO/Co(3)O(4) composite supported on Ni foam

A CdCO(3)/CdO/Co(3)O(4) composite has been prepared on nickel foam through a combined hydrothermal-annealing method. An asymmetric hybrid supercapacitor (SC) device was assembled with this composite as the positive electrode and activated carbon was the negative electrode. The SC exhibited a high sp...

description A CdCO(3)/CdO/Co(3)O(4) composite has been prepared on nickel foam through a combined hydrothermal-annealing method. An asymmetric hybrid supercapacitor (SC) device was assembled with this composite as the positive electrode and activated carbon was the negative electrode. The SC exhibited a high specific capacitance of 84 F g(−1) @ 1 mA cm(−2), a maximum energy density of 26.3 W h kg(−1), and a power density of 2290 W kg(−1), along with a wide potential window of 1.5 V and long cycle life (92% after 6000 cycles). SCs assembled in series powered various light-emitting diodes and moved an electrical mini-motor.
