Scientists create battery that refuels electric cars in seconds

Electric car being charged at a charging stationScottish scientists have developed a liquid battery which could charge electric cars in seconds. A team at the University of Glasgow has created a prototype system that could revolutionise travel.

The technology uses a metal oxide – described by researchers as an “exotic rust” – that can be charged with electricity when added to water.

Drivers would use filling stations to refuel their electric cars, driving away instantly once a battery is full.

Prof Lee Cronin, who is part of the research team, said the liquid battery could hold the key to making electric cars a viable option to fossil-fuelled vehicles.

Prof Cronin told BBC Radio’s Good Morning Scotland programme: “This will overcome a big kind of cultural inertia – you can get instant refuel in the same way, with no change to your behaviour now.

“Because it’s a liquid it would just work as normal using the same infrastructure.

“It will certainly be a game changer if we can make sure that the prototype scales as we expect.”

Drivers would remove the spent “rust” liquid using a withdrawal nozzle at the pump.

They would then use a second nozzle to refill the battery with fresh liquid from the pump.

The Glasgow team said the liquid would provide the same range of miles as conventional fossil fuel.

And Prof Cronin said his liquid battery did not age in the same way as current electric systems.
