Abstract
Asymmetric supercapacitors (ASC) using traditional porous carbon as negative electrode usually suffer from low energy density. Herein, we report a high-performance negative electrode by growing columnar Fe2O3 nanorods vertically on activated hollow yet conductive carbon fiber (aCF), featuring bundled nanorods with a diameter of 50
