One technical area where we can still greatly improve the electric vehicle is in the battery department. One promising technology sofar is called graphene, a material build up of a sheet of carbon. What make graphene so special then? It is only one atom thick! For an impression refer to the image attached to this post.
Graphene is said to have great mechanical strength, but also in conductivity. This last property makes interesting for electronics, but alsofor batteries. In a battery it can help increase the rate of charging (or discharging, but that has not really been a big issue yet). Keep an eye out for more news on this material.
Discoverers of graphene bring graphene-based electronics a step closer
“Although the exciting physics which we have found in this particular experiment may have an immediate implementation in practical electronic devices, the further understanding of the electronic properties of this material will bring us a step closer to the development of graphene electronics,” said Professor Novoselov.
