Abstract
Fabricating fiber-based electrodes with a large specific surface area while maintaining high flow permeability is a challenging issue in developing high-performance redox flow batteries. Here, a sponge-like microfiber carbon electrode is reported with a specific surface area of as large as 853.6 m(2) g(-1) while maintaining a fiber diameter in the range of 5-7 mu m and a macropore size of approximate to 26.8 mu m. The electrode is developed by electrospinning cross-linked poly(vinyl alcohol)-lignin-polytetrafluoroethylene precursors, followed by oxidation and pyrolysis. Applying the as-synthesized electrodes to a vanadium redox flow battery enables the battery to achieve an energy efficiency of 79.1% at the current density of 400 mA cm(-2) and a capacity retention rate of 99.94% over 2000 cycles, representing one of the best battery performances in the open literature. The strategy to fabricate sponge-like porous carbon microfibers holds great promise for versatile applications in redox flow batteries and other energy storage systems.
