【摘要】：炭材料在全钒氧化还原液流电池(钒电池)中主要用作电极。由于传统炭材料对钒电对氧化还原反应的电化学活性较差,因此,对以石墨毡为代表的炭材料电化学活性研究成为钒电池电极研究的重要组成部分。研究从石墨毡电极改性和炭材料作为催化剂应用两方面详述炭材料在钒电池中的电化学活性研究现状,先介绍含氧官能团和含氮官能团对钒电对氧化还原反应的电催化作用,回顾碳纳米管和石墨烯两类新型炭材料在钒电池中的应用。对炭材料电化学活性的今后研究工作进行展望,通过对炭材料性构关系的全面了解和对碳电极上的钒电对电化学反应过程动力学的深入研究,才能为炭材料在钒电池中的实际应用奠定扎实的理论和应用基础。
[Abstract]:Carbon material is mainly used as electrode in vanadium redox liquid flow battery (vanadium battery). Because of the poor electrochemical activity of traditional carbon materials to vanadium electrochemical redox reaction, the study on electrochemical activity of carbon materials represented by graphite felt has become an important part of vanadium battery electrode research. In this paper, the electrochemical activity of carbon in vanadium batteries is described in detail from the aspects of graphite felt electrode modification and carbon material as catalyst. The electrocatalytic effects of oxygen containing functional groups and nitrogen-containing functional groups on the redox reaction of vanadium are introduced. The applications of carbon nanotubes and graphene in vanadium batteries were reviewed. The future research work on the electrochemical activity of carbon materials is prospected, and the kinetics of electrochemical reaction of vanadium on the carbon electrode is studied through a comprehensive understanding of the relationship between the properties of carbon materials and the electrochemical reaction. In order to lay a solid theoretical and application foundation for the practical application of carbon materials in vanadium batteries.
