Summary: As a unique elemental metallic Dirac material, borophene has shown great potential in electronics due to its increasing mechanical and electronic characteristics. In this study, a reliable method is proposed to explore the application of borophene in flexible electrodes by randomly stacking MXene and borophene flakes. It is found that the insertion of borophene remarkably enhances the energy storage capability and energy output of the hybrid film electrode, showing outstanding specific areal capacitance and excellent cyclic stability.
