Signal of change / Tiny batteries charge phones in seconds and last for a week

In an attempt to tackle the issue in smartphones, a team of scientists at the University of Central Florida (UCF) has created a tiny supercapacitor battery that can last for days with only a few seconds’ charge. The research was published in October in the academic journal ACS Nano.

The supercapacitors inside the battery store large amounts of energy and can be recharged more than 30,000 times, compared to typical lithium-ion batteries which start to drain after 300 to 500 full charges, on average.

So what?

The materials supersede conventional ones worldwide in terms of energy density, power density and cyclic stability for small electronic devices. In addition to phones and other electronic gadgets, such as wearables, the small and flexible batteries could be used in electric vehicles and in decentralised forms of energy storage.

Although not ready for commercialisation, this study highlights the very high impacts supercapacitors could have for many technologies, with improvements to energy efficiency and storage alleviating energy waste and consumption.
