Better range, faster recharging being researched for future EVs
In a recent study, new materials which can provide an alternative to battery power have been discovered. It is believed to be 1,000-10,000 times more powerful compared to the supercapacitator, which is the current battery alternative.
This research developed by the University of Surrey and Augmented Optics Ltd. as well as the University of Bristol, could have a great impact on several industries such as transport, aerospace, energy generation, and gadgets or TVs.
In addition, they claim that it also provides a safer, faster charging, more efficient, and greener alternative to battery power.
Supercapacitators provide energy faster compared than the batteries used by most today. It has the capacity to charge and discharge faster. However, due to the poor energy density per kilogram, they've been unable to compete with the conventional battery energy storage in many applications.
Buses powered by supercapacitators are already out in China. However, they could only travel a very limited distance due to the need to re-charge for every 2 to 3 stops.
With this new breakthrough, the previous recharging time of every 2 to 3 stops will be done every 20 to 30 stops. It could revolutionize electric cars, enabling them to travel the same range as gasoline-powered cars as well as decrease charging time from 6 to 8 hours to only a few seconds.
“It is a privilege to work with the teams from the University of Surrey and the University of Bristol. The test results from the new polymers suggest that extremely high energy density supercapacitors could be constructed in the very new future. We are now actively seeking commercial partners in order to supply our polymers and offer assistance to build these ultra high energy density storage devices,” said Jim Heathcote, Chief Executive of both Augmented Optics Ltd and Supercapacitor Materials Ltd.
