US researchers have developed a near-instantaneous charging method for electric and hybrid vehicle batteries. The approach involves replacing a battery electrolyte solution rather than electrically charging the battery as is the current approach. The spent electrolytes would be collected from charging stations and "recharged" using sustainable electricity, from a solar or wind plant. “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,” team leaders John Cushman explains.
