New battery design could charge an electric car in just 10 minutes

WASHINGTON – Scientists in the U.S. have claimed a technological breakthrough that could resolve one of the key concerns surrounding all-electric vehicles, saying just 10 minutes of charging time could add 200 miles (320 km) of driving range.

Writing in the journal Joule on Wednesday, researchers at Pennsylvania State University said that such a speedy charge rate required a battery to rapidly take in 400 kilowatts of energy.

Current-generation vehicles are not capable of this feat because it risks lithium plating — the formation of metallic lithium around the anode — which would severely deteriorate battery life.

To get around this constraint, the researchers raised the temperature of their experimental battery to 60 degrees Celsius (140 Fahrenheit) during the charge cycle, then lowered it back down as it was used .. (snip)

The current generation of Tesla vehicles require about 30 minutes for a partial charge.

Still, Whittingham said, “If you look at the sellers of electricity, they don’t particularly want cars to be charged very fast.”
