摘要

In this paper, we successfully designed and synthesized Co _(3) S _(4) /NiS nanoplates by both ion-exchange action and Ostwald ripening reactions during the sulfurization process. As asymmetric supercapacitor electrode material, Co _(3) S _(4) /NiS exhibited an ultra-high specific capacitance of 1810 mF cm ~(?2) at a current density of 4 mA cm ~(?2) , 12 times larger than the pristine Co _(3) O _(4) electrode, as well as good rate capability and excellent cycling stability. The asymmetric supercapacitor based on Co _(3) S _(4) /NiS can work steadily at a voltage of 1.6 V and deliver a high energy density of 6.44 W h m ~(?2) at a high power density of 32 W m ~(?2) . Moreover, we applied this device to successfully light light-emitting-diodes in a simulated solar illumination system. The perfect integration of two types of capacitor materials into Co _(3) S _(4) /NiS satisfies the requirements of high energy density supercapacitor. Co _(3) S _(4) /NiS nanoplates may have practical applications in the field of energy storage.
