Scientists at the University of Central Florida (University of Central Florida or UCF) have developed a prototype battery-superconductor that lasts 20 times longer than a conventional lithium-ion battery. The original loads 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 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 loading 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.
The new battery's supercapacitors charge quickly because of the way they store energy: statically, on the surface of the material. Simple batteries, on the other hand, rely on chemicals reactions to store energy. Using graphene, the researchers created a large surface area that can hold more electrons, 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.
