中国科学院电工研究所的研究人员在石墨烯量化制备及高性能石墨烯基超级电容器方面取得重要进展,以二氧化碳为原料,采用自蔓延高温合成技术,成功实现了兼具高导电性和高比表面积石墨烯粉体的快速、绿色、低成本制备,并申请了国家发明专利和PCT专利。目前,石墨烯粉体规模化制备的技术路线主要基于膨胀石墨剥离法和氧化石墨还原法来实现,但是前者通常得到的是低比表面积的 Researchers at the Institute of Electrical Engineering, Chinese Academy of Sciences have made important progress in the quantitative preparation of graphene and high performance graphene-based supercapacitors. Using carbon dioxide as a raw material and self-propagating high temperature synthesis technology, the successful achievement of both high conductivity and high specific surface area Graphene powder fast, green, low-cost preparation, and applied for national invention patents and PCT patents. At present, the technical route of large-scale graphene powder preparation is mainly based on the exfoliated graphite exfoliation method and the graphite oxide reduction method. However, the former generally obtains low specific surface area
