Liquid Battery Technology Could Reduce Charge Time To Seconds

Tue 14th Aug 2018

Scientists at the University of Glasgow could have made a major breakthrough in electric vehicle technology with a battery that could be recharged in seconds.

The research has developed a new flow battery system that uses nano-molecules to store electric power. This charged liquid material can then be pumped straight into a car, like a traditional fuel fill up, with the old battery liquid removed at the same time.

The use of a concentrated liquid containing nano-molecules can also increase energy storage by almost 10 times which will excite those currently developing electric vehicles. The development in Scotland is currently at a very early test stage and with no car manufacturers thought to be involved in the research it is unknown if the technology will ever be used in a production car.

"For future renewables to be effective, high capacity and flexible energy storage systems are needed to smooth out the peaks and troughs in supply," said Professor Leroy Cronin from the University of Glasgow.

"Our approach will provide a new route to do this electrochemically and could even have application in electric cars where batteries can still take hours to recharge and have limited capacity.

"Moreover, the very high energy density of our material could increase the range of electric cars, and also increase the resilience of energy storage systems to keep the lights on at times of peak demand."

Lithium ion batteries are heavy and expensive compared to traditional fuel options, they can also take between 45 minutes and 17 hours to recharge.
