At this time more and more busses like the 1E bus in Serbia are relying on the use of a graphene battery. Again, the ability to use a battery for so much more time than ever before is extremely impressive.
This incredibly strong material is extracted from a graphite block and shows an anatomical structure that even impresses the scientific community. Made of a honeycomb shape, when seen microscopically, this can be used for many purposes.
After several attempts to create thin layers of graphene from the graphite blocks, it was finally accepted by the scientific community that there really was something very remarkable about to break through.
