Recently, two new generation of high-specific energy graphene supercapacitors independently developed by CRRC Corporation passed the identification of scientific and technological achievements, and the new generation of large-capacity graphene supercapacitors doubled the specific energy density and can achieve mass production
.
The two products are "3V/12000 Farad Graphene/Activated Carbon Composite Electrode Supercapacitor" and "2.
8V/30000 Farad Graphene Nano Hybrid Supercapacitor"
.
The former can be fully charged in 30 seconds, and the range of a single charge can reach 6 kilometers, which is suitable for driving energy-storage urban rail trains charged at stops; The latter can be fully charged in 1 minute, and the mileage of a single charge can be increased from the current 4~6 kilometers to 8~10 kilometers, which is suitable for driving urban trackless electric buses and can meet the requirements
of charging only at the starting station of the line.
An expert group composed of 9 experts such as Yang Yusheng and Liu Youmei, academicians of the Chinese Academy of Engineering, believes that these two products represent the highest level of supercapacitor monomer technology in the world, and their core parameters have a specific energy density of up to 11 watt-hours / kg, which is double
the highest level of 5 watt-hours / kg in the United States, South Korea and other countries.
Ruan Dianbo, deputy director of the Technology Center of CRRC Corporation and director of Ningbo Supercapacitor Research Institute, said that supercapacitors are physical energy storage and have the advantage of high specific power density, but low specific energy density has always been its weakness
.
The company took the lead in establishing a supercapacitor research institute in the country, and with the support of the national 863 plan project, it focused on improving the specific energy density and other problems, and directly oriented to industrialization
