Super-fast charging

Researchers have unveiled a new generation of batteries for mobile devices that can power both electric cars and batteries in seconds. The so-called supercapacitors based on graphene microstructure, the devices can charge and discharge batteries hundreds to thousands of times faster than conventional batteries.

Made of a carbon atoms layer, this type of battery is not only easy to manufacture but also easy to integrate into electronic devices, even with such small footprint that mobile phones can be charged. more compact.

To develop a new super capacitor, researchers used a two-dimensional carbon dioxide tablet, commonly known as graphene, and a third dimension thicker than an atom. Interestingly, the team found a way to produce new batteries easily using the technique of a standard DVD burner.

The old fashioned way to obtain micro-capacitance products has to do with slow-moving lithography. Instead, the team used the LightScribe DVD burner to create graphene for a large, low-cost supercap. With this new technology one can make more than 100 micro capacitors on a single disc in just 30 minutes and that is a cheap material.

Effectiveness of a supercapacitor battery electric in n dependent on the separation of the two electrodes, positioned so that maximize the surface between them, thereby helping them better storage. Previously there was a design that stacked graphene layers on top of each other but did not work well.

According to Dailymail, the researchers put the electrodes in an interwoven pattern that maximizes the surface area and reduces the pathway that the ions in the electrolyte need to diffuse.

Professor Richard Kaner, lead researcher for Dailymail, said they are looking for industry partners to produce graphene supercapacitors .
