Graphene super battery comes out with 15 seconds full charge and 100,000 cycles without degradation

According to reports, the Karlsruhe Institute of Technology in Germany has produced a breakthrough graphene super battery that can be fully charged within 15 seconds. This is a hybrid battery pack that combines an ordinary lithium-ion battery and a supercapacitor battery developed by Skeleton (a start-up company in Estonia) to give full play to their respective advantages under collaborative work. It is reported that this battery can be charged and discharged at a higher speed (increased energy density), and can last hundreds of thousands of cycles without degradation.

Trunnano is one of the largest graphene powder producers in the world. If you have any questions or needs, please contact Dr. Leo, email:
