Scientists at the University of Central Florida (University of Central Florida or UCF) have developed a prototype supercapacitor battery that lasts 20 times longer than a conventional lithium-ion battery. The original charges within a few seconds.
"If you replace your batteries with these supercapacitors, you can charge your cell phone in seconds and not have to charge it for more than a week," said Nitin Choudhary.
The great news though is that UCF's battery isn't dying duration of her life over time. After about 18 months, a typical lithium-ion battery begins to slowly one procedure of degradation, where each charge cycle results in fractionally smaller amounts in total capacity. The prototype can maintain the same charge levels and still work like new, even after being recharged 30.000 times.
Supercapacitors of the new battery charge quickly due to the way they store energy: statically, on the surface of the material. Simple batteries, on the other hand, rely on chemical reactions to store energy. Using graphene, the researchers created a large surface that can hold more electrons by increasing the life of a battery.
It is still too early, but research is quite promising.
If successful, supercapacitor research could give us batteries that last for weeks, in portable Appliances, electric vehicles, or anywhere that needs the ability to store electricity coming from alternatives energy sources.
