Charging a phone in 30 seconds, an electric car in a matter of minutes is no longer science fiction. Two American researchers have developed a revolutionary graphene-based super-capacitor. Ultra-powerful, super-resistant, flexible and biodegradable, this battery of the future offers very promising development opportunities.
We rub shoulders with graphene from a very young age without really knowing it. It is a carbon crystal that is found in particular in the form of graphite in the mines of our pencils. Its discovery by two researchers from the University of Manchester dates back to 2004. The duo of scientists were awarded the Nobel Prize in Physics for their work in 2010.
Unexpected discovery
The greatest discoveries are often the result of chance, error or accident. The idea holds true for our future stack. After depositing liquid graphite oxide on a CD, Richard Kaner and Maher El-Kady, two other researchers from the University of California solidified the substance using the laser of a computer burner. They then realize by testing it with an electronic device and an LED that it remains lit several minutes after having loaded graphene only a few seconds. Eureka!
Ultra-powerful and biodegradable
As soon as plugged in, as soon as charged. Barely 30 seconds for a smartphone, a few minutes at most for an electric car, it is the time, or the instant, that it will take to charge our electric devices tomorrow. Not content with being the best known electrical conductor to date, graphene has many advantages: it is ultra-powerful, super-resistant and flexible. And the icing on the cake, it is also biodegradable. Made up of carbon atoms, it is therefore possible to make compost alongside plant waste.
