Engineers at Penn State University in the US have claimed to have developed a electric vehicle (EV) battery that is able to recharge in 10 minutes.
The research, covered by Energy Voice on 30 October, found that heating lithium-ion batteries to 60C for 10 minutes, before rapidly cooling again to ambient temperatures, could see lithium spikes and heat damage avoided. They developed a battery design that is self-heating, using a thin nickel foil to create an electrical circuit that heats in less than 30 seconds to warm inside the battery. The rapid cooling required post-charging would be done using the cooling system designed into the car.
The study was published in the journal, Joule, and showed that the design could charge an EV in 10 minutes and, furthermore, that the battery could be recharged many times.
Professor Chao-Yang Wang at Penn State said: “We demonstrated that we can charge an electrical vehicle in 10 minutes for a 200 to 300-mile range, and we can do this maintaining 2,500 charging cycles, or the equivalent of half a million miles of travel. The 10-minute trend is for the future and is essential for adoption of electric vehicles because it solves the range anxiety problem.”
