Facile synthesis of 3D flower-like porous NiO architectures with an excellent capacitance performance

Abstract

3D flower-like porous NiO architectures were synthesized via a facile and green method. When applied as an electrode material for supercapacitors, the as-prepared 3D flower-like porous NiO exhibited an outstanding electrochemical performance, such as a high specific capacitance (1609 F gāˆ’1 at 2 A gāˆ’1), and a long-term cycling stability (4.3% loss after 3000 cycles). The excellent electrochemical performance is mainly attributed to the morphology of the porous ultrathin nanosheets self-assembling into flower-like architectures, which facilitate fast and efficient diffusion of the electrolyte ions. Thus, it is expected that the 3D flower-like porous NiO can be a perspective electrode material for electrochemical energy storage applications.
