Supercapacitors will replace batteries in electric vehicles, allowing them to be charged in a matter of seconds, according to a research group working with the University of Surrey and University of Bristol.
The group claims to have reached a breakthrough in its research into EV batteries and says supercapacitors are proven to be between 1000 and 10,000 times more powerful than equivalent batteries.
This breakthrough could finally allow battery-electric vehicles to have ranges as long as those of fossil-fuelled cars, along with similar refuelling times. The group also described supercapacitors as being more efficient and greener, suggesting that they may waste less energy and have a smaller environmental impact than regular electric vehicle powertrains.
The research into new materials was the cause of the breakthrough, and despite a lower current projected energy density than the traditional lithium-ion batteries used in EVs - meaning a lower storage capacity per kilogram, until the energy density of the tech increases - the considerably quicker charge time of the research group's supercapacitor system means that "A lot of people would be more happy with a half the range of a 300-mile, lithium ion-batteried EV, but a fast charging time", said chief executive of Augmented Optics Ltd and Supercapacitor Materials Ltd, Jim Heathcote.
These conclusions were made by the two universities in co-operation with Augmented Optics, a company that owns Supercapacitor Materials Ltd, with the group adding that supercapacitors will “revolutionise the capabilities of appliances that have previously relied on battery power to work". Laptops, mobile phones and tablet computers are all targeted by the group as areas for potential change.
