At the end of September last year, the Karlsruhe Institute of Technology in Germany and the supercapacitor manufacturer Skeleton Technologies announced that they had jointly developed a "graphene super battery", which attracted a lot of attention.

It is understood that the charging speed of this battery is 1000 times that of ordinary lithium batteries, and it takes only 15 seconds to fully charge. And after hundreds of thousands of charging and discharging experiments, the charging effect of the battery remains unchanged. It can be said that the life and charging speed of this super battery are worthy of the word "super".

Of course, it should be noted that this battery is still in the development and testing stage, and it is still a few years away from commercial use. Moreover, it also has defects such as inability to store energy for a long time and large volume, which needs to be improved. However, the advent of this super battery will undoubtedly bring "sunlight" to the battery industry.
