摘要:

电极是全钒液流电池的重要组成部分,是电解液中不同价态钒离子发生电化学反应的场所。理想的液流电池电极需要同时具备电导率高、比表面积大、润湿性好、耐腐蚀、成本低廉的特性,而目前的材料往往不能兼顾。生物质衍生碳材料具有独特的多孔结构,且含有丰富的氧官能团和氮、磷、硫等元素,可以为电化学反应提供更多的活性位点,被广泛应用于电极材料中。本文回顾了生物质衍生碳材料作为电极或电极催化剂,在全钒液流电池中的应用和研究进展,重点讨论了材料的制备方法、结构组成及其电化学性能,有利于加深人们对电极“构-效关系”的理解,以期设计出更好的电极材料,提高全钒液流电池的性能,降低成本,推进全钒液流电池产业化的发展。

Abstract:

Electrode is a vital component of all vanadium flow batteries and the place where the redox reaction occurs. High conductivity, big specific surface area, superior wettability, corrosion resistance, and low cost are all characteristics of an ideal flow battery electrode. Carbon compounds generated from biomass have a porous structure and are high in oxygen functional groups, as well as nitrogen, phosphorus, sulfur, and other elements. They are widely employed in electrode materials by providing active sites on surface. In this research, we review the application and research progress of biomass-derived carbon materials as electrodes or electrode catalysts in all vanadium flow batteries. The materials' structure, composition, and electrochemical characteristics are examined in detail. It will aid in the improved design of electrode materials, as well as the performance, cost reduction, and industrialization of VFB.

Key words: biomass-derived carbon materials, biomass, flow battery, electrode modification, energy storage
