石油沥青基碳材料在电化学储能中的应用

Application of petroleum asphalt-based carbon materials in electrochemical energy storage

石油沥青是石油加工过程中产生的最难处理的副产品之一,对其进行经济、高效的定向转化是具有重要市场价值和重大战略意义的研究.石油沥青的结构和组成复杂,本文从石油沥青氢碳比低且富含多环芳烃的特点出发,针对电化学储能应用领域,重点综述和展望了石油沥青基纳米碳材料的制备、改性及其在二次电池和超级电容器电极材料方面的应用研究进展,为石油沥青的高附加值利用提供技术方法和研究思路.

Asphalt is one of the most difficult byproducts to deal with in the petroleum processing process, and how to carry out economic and efficient directional transformation is an important research topic with high market value and great strategic significance. The composition and structure of petroleum asphalt are extraordinary complex, which have low hydrogen/carbon ratio and rich polycyclic aromatic hydrocarbons features. In view of the application of petroleum asphalt in the field of electrochemical energy storage, this review focuses on the research progress of the preparation and modification of petroleum asphalt-based nano carbon materials and their applications in the electrode materials of secondary battery and supercapacitor. This review may provide new technical approach and research ideas for the high value-added use of petroleum asphalt.
