Abstract
Supercapacitors integrate advantages of both common capacitors and chemical batteries, and have significant advantages such as high power density, fast charging & discharging speed, and long cycle life. The key to developing supercapacitors is electrode materials, among which the most ideal one is graphene due to its excellent properties in mechanical, electrical, thermal and other aspects. Based on statistical analysis of academic papers and patents related to graphene-based supercapacitors, this paper discusses the development status and direction of graphene-based supercapacitors and briefly describes its domestic industrial development. The difficulties and challenges faced by the future development of graphene-based supercapacitors are discussed and the future development direction and suggestions are proposed.
