• surface area of CGCNFs, thereby significantly increasing their specific capacitance. In addition, the ordering of CGCNFs within the electrode improved the electron transfer efficiency, resulting in a higher specific capacitance. Keywords: carbon/graphene composite nanofibers; carbonization

• magnetic stirring for 2 h to obtain a 2 wt % homogeneous electrospinning solution. Preparation of carbon/graphene composite nanofibers The ordered porous CGCNFs were prepared by MPEM and then submitted to carbonization under a N2 atmosphere at 1100 °C, as shown in Figure 1. The MPEM apparatus is composed
