Manufacturing proper electrodes for supercapacitors including high capacitance is of great importance for current increased demand for energy storage devices. In this paper, we evaluated metal nanoparticles infused in electrospun carbon nanofibers (ECNF) synthesized by electrospinning, followed by thermal treatment for supercapacitors’ electrode applications. The electrodes were characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and cyclic voltammetry. The characterization results indicated that the metal/ECNF samples have fibrous morphology, porous structure with a high specific surface area, including dispersed metal nanoparticles. The effect of embedding various transition metals, such as Co, Ni, and Cu on the electrochemical performance of ECNF has been investigated. The incorporation of Cu into ECNF resulted in the highest specific capacitance. At the scan rate of 5 mV s⁻¹, the specific capacitance of the Cu/ECNF sample was 332 F g⁻¹ while it was 4 F g⁻¹ for the ECNF sample.

对于当前对能量存储设备的需求增加，制造用于包括高电容的超级电容器的合适电极非常重要。在本文中，我们评估了在静电纺丝合成的电纺碳纳米纤维（ECNF）中注入的金属纳米颗粒，然后对其进行热处理以用于超级电容器的电极应用。通过X射线衍射（XRD），拉曼光谱，扫描电子显微镜（SEM）和循环伏安法对电极进行表征。表征结果表明，金属/ ECNF样品具有纤维形态，具有高比表面积的多孔结构，包括分散的金属纳米颗粒。研究了嵌入各种过渡金属（如Co，Ni和Cu）对ECNF电化学性能的影响。将铜掺入ECNF可获得最高的比电容。扫描速率为5 mV s^-1，Cu / ECNF样品的比电容为332 F g ^-1，而ECNF样品的比电容为4 F g ^-1。
