CRRC graphene supercapacitor technology has reached the world's highest level

Recently, at the Zhejiang Provincial Scientific and Technological Achievements and New Product Appraisal Conference, CRRC developed "3V/12000 Farad Graphene/Activated Carbon Composite Electrode Supercapacitor" and "2.
8V/30000 Farad Graphene Nano Hybrid Supercapacitor" were identified as the highest level of supercapacitor monomer technology in the world, and technology research and development continues to be at the forefront of the world
.

According to different capacities and rated working voltages, 3V/12000 Farad supercapacitors can be fully charged in 30 seconds, 2.
8V/30000 Farad supercapacitors can be charged in 1 minute, and the driving range can be increased from the current 4-6 kilometers to 8-10 kilometers, realizing the requirement
that the vehicle only needs to be charged at the end of the station.
Compared with activated carbon supercapacitors, graphene/activated carbon composite electrode supercapacitors have greater energy and longer
life.

In addition to the advantages of "charging times up to 1 million times and charging time as short as tens of seconds", supercapacitors are also attractive advantages of no pollution and explosion risk
.
Ruan Dianbo, deputy director of CRRC's technical center, said that at present, about 60,000 buses are updated online every year in mainland China, and if all use this supercapacitor as the main drive power supply, it can save 584 million kWh of electricity and reduce carbon dioxide emissions by 6.
7 million tons
per year.
