“…Graphene is another allotrope of carbon material, which has one atom thin-layered material with sp 2 hybridized carbon lattice. Graphene is a two-dimensional layered structure with extraordinary physico-chemical properties like high surface area, higher electrical, mechanical properties and electrochemical performance and so on [128][129][130][131]. Due to its extraordinary properties, it is highly utilized for different energy conversion and storage applications.…”

“…Over the last few decades, a range of energy storage devices, such as solar cells, batteries, lithium-ion batteries, electrochemical capacitors, fuel cells, and supercapacitors (SCs), have been reported [4]. Among the above energy storage devices, SCs have considerable potential and are used widely in storage devices owing to their rapid charge-discharge cycle performance, outstanding cyclability, eco-friendly nature, long cycling life span, and high rate abilities [5][6][7]. Various materials for faradic redox reactions (pseudocapacitors (PCs), such as Co 3 O 4 , NiO, MnO 2 , and RuO 2 , have been used as electrodes to achieve high energy capability for SCs [8,9].…”

NiCo 2 O 4 nanoleaf arrays (NCO NLAs) and NiCo 2 O 4 /NiCO 2 O 4 nanofile arrays (NCO/NCO NFAs) material was fabricated on flexible nickel foam (NF) using a facile hydrothermal approach. The electrochemical performance, including the specific capacitance, charge/discharge cycles, and lifecycle of the material after the hydrothermal treatment, was assessed. The morphological and structural behaviors of the NF@NCO NLAs and NF@NCO/NCO NFAs electrodes were analyzed using a range of analysis techniques. The as-obtained nanocomposite of the NF@NCO/NCO NFAs material delivered outstanding electrochemical performance, including an ultrahigh specific capacitance (Cs) of 2312 F g −1 at a current density of 2 mA cm −2 , along with excellent cycling stability (98.7% capacitance retention after 5000 cycles at 5 mA cm −2 ). These values were higher than those of NF@NCO NLAs (Cs of 1950 F g −1 and 96.3% retention). The enhanced specific capacitance was attributed to the large electrochemical surface area, which allows for higher electrical conductivity and rapid transport between the electrons and ions as well as a much lower charge-transfer resistance and superior rate capability. These results clearly show that a combination of two types of binary metal oxides could be favorable for improving electrochemical performance and is expected to play a major role in the future development of nanofile-like composites (NF@NCO/NCO NFAs) for supercapacitor applications.

“…Nevertheless they show significantly lower specific energy density compared to batteries. Therefore, the development of high performance supercapacitors with high specific energy density, power density and cycle stability is desirable for practical applications in storage devices . Based on the energy storage mechanism, there are two types of supercapacitors, namely electrochemical double layer capacitors (EDLCs) and pseudocapacitors.…”

In this report, graphene oxide (GO)-supported sheet-like CuO nanostructures have been fabricated through a novel room temperature method using copper-based metal-organic framework (MOF)-anchored graphene oxides. Copper terephthalate metal-organic framework (Cu-(BDC)-MOF) crystals were synthesized onto the surfaces of exfoliated graphene layers via coordination of the metallic centers with the oxygen functionalities of graphene oxides and terephthalate linkers. The alkaline ageing of the MOF supported graphene oxides in NaOH at ambient temperature leads to the GO/CuO hybrid nanostructures. The morphology and structure of the synthesized materials are examined by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM) and selected area electron diffraction (SAED). The well-dispersed sheet-like CuO nanostructures on graphene oxides show excellent performance in supercapacitor applications.The GO/CuO hybrid nanostructures are capable of delivering a high specific capacitance of 606 F g À 1 at scan rate of 2 mV s -1 with excellent cycling stability over 93% retention of initial capacitance.
