A liquid-based battery developed by scientists at the University of Glasgow in Scotland could enable electric vehicles to recharge in seconds, a report from the BBC claims.
The battery uses a type of metal oxide that interacts with a liquid to produce a charge. The battery could be instantly recharged using a nozzle that would draw the spent liquid out of the battery pack and replace it. Prof. Lee Cronin, who spoke to the BBC about the technology, said laboratory tests of the technology have gone positively, but they are now tasked with scaling it so it could work on a passenger vehicle.
“It will certainly be a game changer if we can make sure that the prototype scales as we expect,” Cronin said.
Flow batteries, like what the BBC report is describing, are often used in stationary power grid storage applications due to their size and weight. This could also be a major issue with scaling a battery pack of this type, although it’s hard to say for sure without knowing more about the University of Glasgow’s technology. The experts behind the tech seem confident, though, with Cronin saying a battery that allows for such short refuelling times could help to enact “a big kind of cultural inertia,” in regards to EV adoption.
While research is still being conducted, Cronin and his team say the scaling of the battery tech is going to plan so far. It will be interesting to see whether the liquid battery or the solid state battery play a larger part in helping the masses to adopt EVs going forward. For what it’s worth, Cronin’s hedging his bets on liquid, saying he could see the technology coexisting with gasoline for quite some time.
