Soon you may be able to charge your smartphone within a few seconds. Scientists have been developing new flexible supercapacitors that can be recharged over 30,000 times before they start degrading. After about a year and a half the smartphones start to hold charge for less time and the battery starts to degrade. Scientists at the University of Central Florida have invented a new process to create super capacitors. This method could ultimately end up revolutionising technology from mobile phones to electric cars.
