New Nanotech could enable Phones to charge in seconds

BITE-SIZE SUPERCAPACITORS

Customer electronic devices are becoming far more strong when shedding or maintaining size. These smaller sized gadgets call for considerable amounts of power, which existing batteries do not effectively deliver, specifically soon after extended use. Scientists in the University of Central Florida (UFC) have created an extremely thin, flexible supercapacitor with higher energy density.

The team from UCF’s NanoScience Technologies Center figured out a solution to use two-dimensional components as supercapacitors, solving the issue of size. Presumably, to get a supercapacitor to hold an equal amount of power as current lithium-ion batteries need to be substantially larger than existing batteries. “We created a very simple chemical synthesis strategy, so we are able to integrate the existing materials with the two-dimensional components incredibly nicely,” stated lead researcher Yeonwoong Jung, an assistant professor at UCF’s NanoScience Technology Center.

The material used in the two-dimensional is called transition-metal dichalcogenides (TMDs). It is not only tiny, but also provides for faster electron transfer which in other words is faster charging and discharging – thanks to a highly conductive core. The supercapacitors are made of millions of nanometer-thick wires with two-dimensional material shells coating.

RESHAPING MOBILE TECHNOLOGY

The supercapacitors are also additional durable. They don’t degrade quickly over time, even just after being recharged 30,000 times. Conversely, lithium-ion batteries suffer in performance immediately after about 1,500 charging cycles.

“If they were to change the batteries with these supercapacitors, it would be possible to charge mobile phones in a matter of seconds and they wouldn’t need to be charged again for over a week,” Nitin Choudhary explained.

The technology is not, however, ready for commercial use, and Jung is actively working to have it patented. If it is successful, it will be the next big thing in electronics, from mobile phones to wearables, and even electronic vehicles.
