“…Crumpled nitrogen-doped graphene-ultrafine Mn3O4 nanohybrids (CNGMNs) were synthesized under hydrothermal conditions [108]. They used the prepared nanohybrids CNGMNs materials as electrodes for supercapacitors, which exhibit improved capacitance approximately 6 times better than that of the Mn3O4 counterpart and display exceptional rate capability and cycling stability (~98.7% retention after 2000 cycles) [108].…”

A comprehensive overview and description of crumpled graphene explored in recent years for energy storage applications is presented. Although graphene is known as one of the best electronic materials, preparing of crumpled graphene has been less explored. This article selectively aims to present an overview of the advancement of research in crumpled graphene, in the area of preparation and applications especially in energy storage, such as supercapacitor and lithium ion batteries. When graphene was transformed to the crumpled form, the resulting one can give superior capacitance due to their unique properties like extremely high specific surface area, high conductivity and stability against graphitization (aggregation-resistant) compared to those of flat graphene sheets which tend to aggregation and thus lead to a dramatic decrease in the surface area, leading to a poor capacitance.

“…electrical double layer capacitors (EDLC) storing energy based on the charge separation at the porous carbon electrode/electrolyte interface, and pseudo-capacitors storing energy by fast, reversible redox reactions at the surface of transition metal oxides (RuO 2 , MnO 2 or NiO x ) [4][5][6][7][8] or conducting polymers (polyanline, polypyrrole or polythiophene) [9,10]. Among the various conducting polymers, polyaniline (PANI) has been considered as a promising candidate due to its high pseudo-capacitance, low cost, facile synthesis and environmental stability.…”

“…3d shows the Nyquist plots of the electrochemical impedance spectroscopy (EIS) for rGO-1, rGO-30, and rGO-60 samples. The rGO-60 displayed the lowest charge-transfer resistance and thus allow for an excellent conductivity due to the higher degree of deoxygenation during the Zn powder treatment compared with rGO-1, rGO-30 [8,15]. These results indicate that rGO-60 is very promising flexible electrode materials for high performance supercapacitors.…”

“…The performance of the material was analyzed on a CHI760D Electrochemical Working Station. From the charge and discharge curves, the specific capacitance (F/g) of the electrode material was calculated using the formula C ¼ IΔt/ΔVm, where Δt is the discharge time (s), I is the discharge current (A), ΔV is the operating potential window (V) during the discharge, and m is the mass (g) of active materials [8].…”
