UCF: Battery charges in seconds and lasts for weeks

Scientists at the University of Central Florida ( 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 in a few seconds .

"If you replace your batteries with these supercapacitors, you can charge your cell phone in seconds and you won't have to charge it again for over a week”, said Nitin Choudhary.UCF supercapacitor

The great thing is that the UCF battery does not lose its lifetime with time. After about 18 months, a typical lithium-ion battery slowly begins a process of degradation, where each cycle s leads to 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, the research of superconductors could give us batteries that last for weeks on portable devices, electric vehicles, or wherever it takes a storage capacity of electricity from alternative energy sources.
