| 英文摘要 | Vanadium flow battery (VFB) is one of the most promising energy storage technologies because of its superior safety, reliability and cycle life, but the poor electrochemical performance at high cur-rent density limits its commercial application. Herein, an advanced design of the dual-gradient carbon nanofibers/graphite felt (DG-CNFs/GF) composite electrode is firstly proposed for the next-generation VFB with high power density. Specifically, there is a macro gradient distribution of CNFs along the thickness direction of the electrode, meanwhile a micro gradient distribution of CNFs is also existed along the ra-dial direction of a single fiber, and both the macro and micro gradient structure are verified through the physicochemical characterizations. In addition, the DG-CNFs/GF with a dual-gradient structure exhibits an excellent electrocatalytic activity and a fast mass transfer characteristic. It is worth noting that the energy conversion efficiencies, cycling stability in addition to power density of VFB with DG-CNFs/GF are much better than those with commercial GF, which make the dual-gradient DG-CNFs/GF to be a promis-ing alternative. Most importantly, the accomplishment of this work will provide a promising development direction of the highly efficient electrode for the next-generation VFB with high power density.
