OMG? Are we going to have super cheap electric vehicles in a few years that charge in a few seconds/minutes?
I hope so! This is very exciting.
Australia has supercapacitors made from graphene oxide. They can can store as much energy per kilogram as a lithium battery, but charges in minutes, or even seconds, and uses carbon instead of expensive lithium.
Large-scale production of the graphene that would be needed to produce these high-performance supercapacitors was once unachievable.
By using low-cost solution-based film synthesis techniques and a laser 3D printer, the researchers are able to produce graphene on a large scale at low cost.
