摘要

A Ni(OH)(2) composite with good electrochemical performances was prepared by a facile method. Ni(OH)(2) was homogeneously grown on the hydrophilic graphene/graphene oxide (G/GO) nanosheets, which can be prepared in large scale in my lab. Then G/GO/Ni(OH)(2) was reduced by L-Ascorbic acid to obtain G/RGO/Ni(OH)(2). Caused by the synergy effects among the components, the G/RGO/Ni(OH)(2) electrode showed good electrochemical properties. The G/RGO/Ni(OH)(2) electrode possessed a specific capacitance as high as 1510 F g (1) at 2 A g (1) and even 890 F g (1) at 40 A g (1). An asymmetric supercapacitor device consisting of G/RGO/Ni(OH)(2) and reduced graphene oxide (RGO) was installed and displayed a high energy density of 44.9 W h kg (1) at the power energy density of 400.1 W kg (1). It was verified that the G/GO nanosheets are ideal supporting material in supercapacitor. (C) 2019 The Society of Powder Technology Japan.
