Progress in application of graphene in supercapacitor and battery

石墨烯因其高的比表面积、优异的导电性、高的电子迁移率和特殊的二维柔性结构,过去十余年在能源领域引发了极大的关注,电化学储能领域被认为是最有可能在短期内实现石墨烯规模应用的产业领域,特别是在超级电容器和电池领域。本文回顾了近年来石墨烯在超级电容器和电池中的应用,介绍了石墨烯导电剂和储能材料在超级电容器中的应用,以及石墨烯在锂电池电极材料和涂层铝箔中的应用。指出了目前石墨烯材料的品质和成本问题仍是严重制约它在储能领域规模化应用的核心要素。未来,迫切需要石墨烯全产业链的协调合作,推进石墨烯储能材料的研发、生产及应用。

In the past ten years,graphene has attracted great attention in the field of energy due to its high surface area,excellent electrical conductivity,high electron mobility and special two-dimensional flexible structure,and is most likely to achieve large-scale application in electrochemical energy storage in the short term,especially in supercapacitor and battery.The paper reviews the recent applications of graphene in supercapacitor and battery,including application of graphene conductive agent and energy storage material in supercapacitor,and application of graphene in lithium-ion battery electrode material and coating aluminum foil.It’s pointed out that the quality and cost of graphene are still the key factors which restrict its large-scale application in energy storage.In the future,there is urgent need for coordination and cooperation of the whole graphene industry chain to promote the research and development,production and application of graphene in energy storage materials.
