Energy storage devices are an important area for future technology that should be used to achieve green energy storage. The supercapacitor is one form of energy storage that has continuously improved in performance. The main parts of a supercapacitor are the electrode and electrolyte parts. The electrode has been improved by the use of graphene material, and electrolytes have been improved by nanofiber separators. The graphene nanosheets (GNs) from the electrolysis process have generated nanoparticles with the smallest diameter of 20.62 nm, with 486.2836 m/g surface area. The nanofiber separator can be produced from an electrospinning technique that generates a fiber of 170 nm in diameter and can satisfactorily absorb 6 M KOH liquid electrolyte. The GN electrodes and nanofiber sheet electrodes (6 M KOH) combined to be a supercapacitor that fabricated high levels of performance at 150 F at 0.6 A/g. Therefore, the GN electrodes and nanofiber sheet separators with 6 M KOH (electrolyte) achieved moderate supercapacitor performance.
储能设备是未来技术的一个重要领域,应用于实现绿色储能。超级电容器是一种储能形式,其性能一直在不断提高。超级电容器的主要部件是电极和电解质部分。电极通过使用石墨烯材料得到了改进,电解质则通过纳米纤维隔膜得到了改进。电解过程中产生的石墨烯纳米片(GNs)生成了直径最小为20.62 nm、表面积为486.2836 m/g的纳米颗粒。纳米纤维隔膜可以通过静电纺丝技术制备,该技术可生成直径为170 nm的纤维,并且能够令人满意地吸收6 M KOH液体电解质。GN电极和纳米纤维片电极(6 M KOH)组合成为一个超级电容器,在0.6 A/g的电流下,150 F时表现出高性能。因此,带有6 M KOH(电解质)的GN电极和纳米纤维片隔膜实现了适度的超级电容器性能。
