| Abstract Scope |
Scalable production of turbostratic holey graphene (tHG) with high energy density and power density is essential but challenging for flexible and compact supercapacitors. Herein, we demonstrate an efficient, rapid, cost-effective and kilogram-scale method for fabricating the twisted multilayer holey graphene using an atmospheric plasma spray. The twisting of graphene layers reduces electronic interactions between them, increasing the spacing between layers and consequently enhancing the graphene's effective specific surface area. The fabricated tHG electrode exhibits the highest specific capacitance of ~250 F g-1 at 0.5 A g-1, an energy density of 28.54 Wh kg-1 and a power density of 280 W kg-1 in the three-electrode system. Furthermore, the electrode exhibits outstanding electrochemical stability, retaining about 94% of its capacitance after 10,000 cycles. These characteristics position the tHG as an auspicious material for next-generation high-performance supercapacitors. |
