Graphene is widely used. According to the ultra-thin and super-strong characteristics of graphene, graphene can be widely used in various fields, such as ultra-light body armor, ultra-thin and ultra-light aircraft materials and so on. Because of its excellent conductivity, it also has great application potential in the field of microelectronics. Graphene may become a substitute for silicon, making ultramicro transistors and producing future supercomputers. The higher electron mobility of carbon will enable future computers to reach higher speeds. In addition, graphene material is an excellent modifier with high conductivity and high specific surface area, which can be used as an electrode material additive in new energy fields such as supercapacitors and lithium-ion batteries.
