IFBattery – Instantaneous Recharging Batteries

An innovation from Perdue University, Laffayette, USA, could dramatically reduce the time needed to recharge a battery. E-vehicles could enter a charging station en route and recharge in a matter of minutes, like in the petrol car days and as such could significantly lower the acceptation threshold for e-vehicles. Gone would be the necessity of a nation-wide power plug infrastructure in front of every home to recharge the car at night.

Purdue scientist John Cushman presented his findings at the recent International Society for Porous Media 9th International Conference in Rotterdam, Netherlands.

Recharging consists of refilling a car with fluid electrolytes, not with electricity kWh’s:

The spent battery fluids or electrolyte could be collected and taken to a solar farm, wind turbine installation or hydroelectric plant for re-charging… 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… Other flow batteries exist, but [this is] the first to remove membranes which reduces costs and extends battery life… Membrane fouling can limit the number of recharge cycles and is a known contributor to many battery fires.
