▎ 摘　　要

Graphene-based electrodes have been fabricated in 1 and 2 T perpendicular and parallel magnetic fields, respectively. By out-of-plane and in-plane XRD analyses, it could be found that in perpendicular magnetic fields, graphene sheets are induced to align perpendicular to the mesh and that the arrangement makes more edge planes exposed to the surface. N-2 adsorption-desorption measurements show that the perpendicular arrangement brings about an increase in surface area and pore size. More important is that the electrochemical performance, such as specific capacitance, cycle stability, and impedance of electrodes, improves as a result of the perpendicular arrangement. However, parallel magnetic fields lead to a decrease in the electrochemical performance and surface properties because of the parallel arrangement of graphene sheets.
