Charging an electric car remains an obstacle for some people, especially in areas lacking charging infrastructure. But new battery technology developed by researchers at Purdue University could change that completely. They’ve designed an instantly rechargeable battery that could allow electric vehicles to be charged in roughly the same amount of time it takes to fill up a car with gasoline today.
The researchers designed a flow battery system, which in itself isn’t unique, but the Purdue scientists removed battery membranes, something they say no one else has done. Membranes in batteries break down over time, so the new battery technology allows for a longer lifespan and cuts costs. This rechargeable battery could be a game changer for electric cars.
Drawing on the Purdue energy storage technology, electric car owners would pull up to a station and fill up their cars with not gas, but fluid electrolytes. The spent battery fluids could be gathered and recharged at a solar or wind farm.
Earth, atmospheric, and planetary science professor John Cushman said in a statement, “Instead of refining petroleum, the refiners would reprocess spent electrolytes and instead of dispensing gas, the fueling stations would dispense a water and ethanol or methanol solution as fluid electrolytes to power vehicles…It is believed that our technology could be nearly ‘drop-in’ ready for most of the underground piping system, rail and truck delivery system, gas stations and refineries.”
They say their instantly rechargeable method is affordable, safe, and environmentally friendly.
Cushman recently presented their findings at the International Society for Porous Media 9th International Conference in the Netherlands. With two other Purdue researchers, he started a company, IFBattery, to commercialize their technology. Cushman said they are seeking financing to develop large-scale prototypes, and from there they’ll look for manufacturing partners.
