Battery that charges in a few seconds and lasts several days now closer to reality

Researchers from University of Central Florida have found a way to improve batteries.

Among the gadget woes of today is the abysmal battery longevity. We have all the processing power and memory in the world but uptime still leaves something to be desired. Fast charging has evolved, wireless charging is now getting more attention, but that’s not enough. At the end of the day, not a lot of smartphones have power left to spare.

Fortunately, researchers have been hard at work in bringing a solution to this situation. Charging devices for hours may seem like little inconvenience for the amount of work we’re getting from them, but innovation is always a good thing. What if it can fully charge in mere seconds? That’s exactly what the team of scientists from UCF did.

They created a method of producing flexible supercapacitors which is capable of storing more energy and can withstand over 30,000 rechargers without degradation. We’ve already heard about this in the past, when a young student from California won second place in the Intel Foundation Young Scientist Awards.

“If they were to replace the batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week,” said Nitin Choudhary, a postdoctoral associate.

Unlike conventional lithium-ion batteries, supercapacitors store the energy power statically on the material instead of by using chemical reactions. Before this study, scientists already knew that two-dimensional materials are of great use for storing electricity. However, the full potential has not been realized until University of Central Florida’s NanoScience Technology Center’s project.

Due to its flexible nature, the supercapacitors that use the new materials can be used on smartphones, tablets, wearables and even electric vehicles.

According to research team lead Yeonwoong “Eric” Jung, the battery technology is not yet ready for commercialization as of the moment.

We can’t be too excited about this development, though, as previous breakthroughs weren’t able to pull it off just yet. Nonetheless, let’s remain optimistic about this new battery technology.
