A Battery Breakthrough

Charge your iPhone in five SECONDS

 

Researchers have revealed a radical new type  of battery that could charge a mobile phone or even a car in seconds.

Called micro-scale graphene-based  supercapacitors, the devices can charge and discharge a hundred to a thousand  times  faster than standard batteries.

Made from a one-atom–thick layer of carbon, can be easily manufactured and readily integrated into gadgets – and could even lead to far smaller phones.

HOW IT WORKS

For any supercapacitor to be  effective, two  separated electrodes have to be positioned so that the  available surface area  between them is maximized.

This allows the  supercapacitor to store a  greater charge.

A previous design stacked the layers  of  graphene serving as electrodes, like the slices of bread on a  sandwich.  However, this didn’t work with electronic cicruits.

In their new design, the researchers  placed  the electrodes side by side using an interdigitated pattern, akin to interwoven  fingers.

This helped to maximize the  accessible  surface area available for each of the two electrodes while  also reducing the  path over which ions in the electrolyte would need to  diffuse.

As a result, the new supercapacitors have  more charge capacity and rate capability than their stacked  counterparts.

The team say their breakthrough could least  to faster charging phones and cars, but also smaller gadgets.

‘The integration of energy-storage units with  electronic circuits is challenging and often limits the  miniaturization of the  entire system,’ said Richard Kaner, who is a professor of materials science and  engineering at UCLA’s Henry Samueli School of Engineering and Applied Science.

To develop their new  micro-supercapacitor,  the researchers used a two-dimensional sheet of  carbon, known as graphene,  which only has the thickness of a single atom in the third dimension.

The team also found a way to produce the new  batteries easily – using a standard DVD burner.

‘Traditional methods for the  fabrication of  micro-supercapacitors involve labor-intensive  lithographic techniques that have  proven difficult for building  cost-effective devices, thus limiting their  commercial application,’  El-Kady said.

‘Instead, we used a consumer-grade  LightScribe DVD burner to produce graphene micro-supercapacitors over  large  areas at a fraction of the cost of traditional devices.

‘Using this technique, we have been  able to  produce more than 100 micro-supercapacitors on a single disc in  less than 30  minutes, using inexpensive materials.’

The researchers say people could even make  the technology at home.

‘The process is straightforward,  cost-effective and can be done at home,’ El-Kady said.

‘One only needs a DVD burner and graphite  oxide dispersion in water, which is  commercially available at a moderate  cost.’

The team say they are now hoping to begin  working with gadget makers.

‘We are now looking for industry partners to  help us mass-produce our graphene micro-supercapacitors,’ Kaner said
