A new generation of graphene supercapacitors come out to achieve mass production

Recently, two new types of high specific graphene supercapacitors developed independently by China Automotive Industry Corporation have passed the scientific and technological achievements appraisal. The new generation of high-capacity graphene supercapacitors has twice the specific energy density and can be mass-produced. The two products are "3V / 12000 Farad / Activated carbon composite electrode supercapacitor" and "2.8V / 30000 Farah nano composite supercapacitor" respectively. The former can be fully charged within 30 seconds, a single charge mileage of up to 6 km, suitable for driving the charging at the docking station energy storage city rail train; the latter can be charged within 1 minute, a single charge Mileage can be increased from the current 4 to 6 km to 8 to 10 km, suitable for driving urban trolley buses, to meet the requirements of charging only at the starting site of the line. Experts from the Chinese Academy of Engineering Yang Yusheng, Liu Youmei and other 9 experts believe that these two products represent the world's highest level of super capacitor monomer technology, the core parameters than the energy density of up to 11 watts / kg, the United States, South Korea and other countries 5 watt hours / kg the highest level doubled. ROC Dianbo, vice director of China Chusuchan Technology Center and director of Ningbo Supercapacitor Institute, said that supercapacitors are physical energy storage, which has advantages over high power density, but has been its weakness over energy density. The company took the lead in establishing the National Institute of Supercapacitors and supported by the National 863 Program and other issues to tackle the issue of specific energy density and other issues, and directly facing the industrialization.
