Nickel cobalt oxide (NCO) is considered an auspicious electrode candidate for the reinforcement of energy-storage devices. Currently, an immense interest is devoted to modifying the morphological aspects of the NCO to boost their surface texture and electrochemical performances, which is feasible for the development of high energy density and durable devices. Herein, we report the synthesis of layered NCO nanosheets via solvothermal reaction by tuning the solvent volume ratio (water/N,N-Dimethylformamide [DMF]) for supercapacitor electrode material. The nickel cobalt oxide is prepared utilizing a 1:2 (DMF:water) ratio of solvent (NCO1) displays a controlled growth of 2D nanosheets with excellent surface texture. Moreover, NCO1 demonstrates the battery type charge storage properties with a maximum specific capacitance (C sp ) of 731 F g À1 , which is far better than NCO2 (623 F g À1 ) and NCO3 (556 F g À1 ) prepared in other solvent proportions. Besides, the constructed hybrid supercapacitor utilizing activated carbon (AC) and NCO1 as the negative and positive electrodes, respectively, exhibits the C sp of 120 F g À1 , and maximum specific energy 37.33 W h kg À1 for the specific power 691.31 W kg À1 and demonstrates excellent stability~80.56% for 20 000 cycles.In different electrochemical energy storage devices, supercapacitors (SCs) have gained abundant consideration as a novel and promising future energy storage device.

“…The sp 2 -hybridized carbon nanomaterials, such as one-dimensional (1D) and twodimensional (2D) nanostructured carbon, exhibit exceptional mechanical strength, electrical conductivity, and adaptability to various interfacial processes [9,10]. Carbon nanomaterials, especially carbon nanotubes (CNTs), carbon nanofibers (CNFs), and graphene, are promising candidates to replace activated carbon as electrode material in high-performance supercapacitors owing to their large surface area, high mesoporosity, electrolyte accessibility, and desirable electrical properties [11].…”

Carbon materials have gained considerable attention in recent years due to their superior properties. Activated carbon has been used in supercapacitors due to its density and rapid adsorption capability. The sp2–sp3 hybrid porous carbon materials are synthesized using herringbone-type carbon nanofibers (CNFs) and carbonized spherical phenol resins, with KOH as the activating agent. The morphology of the hybrid porous carbon facilitates the formation of ribbon-like nanosheets from highly activated CNFs wrapped around spherical resin-based activated carbon. The etching and separation of the CNFs produce a thin ribbon-like nanosheet structure; these CNFs simultaneously form new bonds with activated carbon, forming the sp2–sp3 hybrid porous structure. The relatively poor electrical conductivity of amorphous carbon is improved by the 3D conductive network that interconnects the CNF and amorphous carbon without requiring additional conductive material. The composite electrode has high electron conductivity and a large surface area with a specific capacitance of 120 F g−1. Thus, the strategy substantially simplifies the hybrid materials of sp2-hybridized CNFs and sp3-hybridized amorphous spherical carbon and significantly improves the comprehensive electrochemical performance of supercapacitors. The developed synthesis strategy provides important insights into the design and fabrication of carbon nanostructures that can be potentially applied as electrode materials for supercapacitors.
