Hexadecyl trimethyl ammonium bromide assisted growth of NiCo(2)O(4)@reduced graphene oxide/ nickel foam nanoneedle arrays with enhanced performance for supercapacitor electrodes

NiCo(2)O(4)@reduced graphene oxide (rGO)/nickel foam (NF) composites were prepared via a hydrothermal method followed by annealing assisted by hexadecyl trimethyl ammonium bromide (CTAB). NiCo(2)O(4)@rGO/NF nanoneedle arrays grew directly on Ni foam (NF) without using a binder. The effect of graphen...

description NiCo(2)O(4)@reduced graphene oxide (rGO)/nickel foam (NF) composites were prepared via a hydrothermal method followed by annealing assisted by hexadecyl trimethyl ammonium bromide (CTAB). NiCo(2)O(4)@rGO/NF nanoneedle arrays grew directly on Ni foam (NF) without using a binder. The effect of graphene oxide (GO) concentration on the electrochemical properties of the composite was studied. When the GO concentration was 5 mg L(−1), the as-prepared NiCo(2)O(4)@rGO/NF reaches the highest specific capacitance of 1644 F g(−1) at a current density of 1 A g(−1). Even at 15 A g(−1), the specific capacitance is still 1167 F g(−1) and the capacitance retention rate is 89% after 10 000 cycles at 10 A g(−1). Furthermore, a NiCo(2)O(4)@rGO/NF//graphene hydrogel (GH) asymmetric supercapacitor cell (ASC) device was assembled and exhibits a high specific capacitance of 84.13 F g(−1) at 1 A g(−1) and excellent cycle stability (113% capacitance retention) after 10 000 charge/discharge cycles at 10 A g(−1). This provides potential for application in the field of supercapacitors due to the outstanding specific capacitance, rate performance and cycle stability of NiCo(2)O(4)@rGO/NF.
