摘　　要：近年来,全钒氧化还原液流电池(VRFB)作为一种新型的储能电池备受关注,作为VRFB的核心材料,电极的活化一直都是研究的热点。碳素类材料,如碳毡和石墨毡,以其低成本和高性能被广泛用作钒电池电极。通过活化处理增加碳素类电极表面的含氧、含氮官能团或引入各种催化剂可以显著提高V(Ⅴ)/V(Ⅳ)和V(Ⅲ)/V(Ⅱ)电对氧化还原反应的电化学活性和可逆性,进而提高VRFB的总体性能,最终促进VRFB的商业化进程。本文综述了VRFB碳素类电极的氧化活化法、掺杂活化法和碳纳米催化剂活化法等几种常用活化方法的研究进展,并对VRFB碳素类电极的进一步研究和应用前景进行了展望。In recent years, all-vanadium redox flow battery （VRFB）has been paid much attention as a new type of battery for energy storage.Researchers have been focusing much on activation of carbon electrodes used for the key material in VRFB.The carbon electrode, such as carbon felts and graphite felts, are widely used as electrode for VRFB due to their low cost and high performance.The electrochemical activation and reversibility towards Ⅴ（Ⅴ）/Ⅴ（Ⅳ）and V（Ⅲ）/Ⅴ（Ⅱ）redox reactions can be significantly improved after increasing the oxygen and nitrogen functional groups on the surface of carbon electrodes or introducing all kinds of catalysts by activation treatment, which can improve the overall performance of VRFB and further accelerate its commercialization process.The research progress in various common activation methods including oxidation activation, doping activation and carbon nanocatalysts activation, are summarized in this paper.The further research and prospect on carbon electrodes in VRFB are also presented.
