“…On the other hand, NiO offers an order of magnitude higher conductivity (10 -2 S m -1 ) despite its relatively lower C S . There have been efforts to enhance electrochemical performance of Co 3 O 4 by the addition of NiO [25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Although improved C S have been reported in many of these works, poor rate capability and device performance were still observed.…”

“…It is well known that carbon materials are fundamental candidates for EDLC 8 . Until now, a variety of carbon materials have been used as the electrode materials such as carbon nanotubes (CNTs) 8 – 10 , carbon nanofibres (CNFs) 11 – 14 , reduced graphene oxide (RGO) and so on 8 , 15 – 17 . Compared with EDLC, PC was major based on transition metal oxides/hydroxides or conducting polymers by redox reactions during charge-discharge processes 8 , 9 , 18 – 20 .…”

A novel NiFe-LDH/RGO/CNFs composite was produced by using a facile one-step hydrothermal method as electrode for supercapacitor. Compared with NiFe-LDH/CNFs, NiFe-LDH/CNTs and NiFe-LDH/RGO, NiFe-LDH/RGO/CNFs demonstrated a high specific capacitance of 1330.2 F g−1 at 1 A g−1 and a super rate capability of 64.2% from 1 to 20 A g−1, indicating great potential for supercapacitor application. Additionally, an asymmetric supercapacitor using NiFe-LDH/RGO/CNFs composite as positive electrode material and activated carbon as negative electrode material was assembled. The asymmetric supercapacitor can work in the voltage range of 0–1.57 V. It displayed high energy density of 33.7 W h kg−1 at power density of 785.8 W kg−1 and excellent cycling stability with 97.1% of the initial capacitance after 2500 cycles at 8 A g−1. Two flexible AC//LDH-RGO-CNFs ASC devices connected in series were able to light up a red LED indicator after being fully charged. The results demonstrate that the AC//LDH-RGO-CNFs ASC has a promising potential in commercial application.

“…In the TGA pattern of the Ni-Co LDH@rGO nanohybrids shown in Fig. 3, three major weight loss stages are observed [39][40][41] . The first weight loss component occurs at~120°C and is attributed to the removal of loosely bound water molecules from the interlayers.…”

Functionalization of graphene-based materials using chemical moieties not only modify the electronic structure of the underlying graphene but also enable in limited enhancement of targeted properties. Surface modification of graphene-based materials using other nanostructures enhances the effective properties by minimally modifying the properties of pristine graphene backbone. In this pursuit, we have synthesized bio-inspired hierarchical nanostructures based on Ni-Co layered double hydroxide on reduced graphene oxide core-shells using template based wet chemical approach. The material synthesized have been characterized structurally and electrochemically. The fabricated dendritic morphology of the composite delivers a high specific capacity of 1056 Cg −1. A cost effective solid state hybrid supercapacitor device was also fabricated using the synthesized electrode material which shows excellent performance with high energy density and fast charging capability.
