Researchers at Penn State University and battery manufacturer EC Power have designed a battery that, in the future, will make it possible to charge an electric car in ten minutes.
The key to the success is that the researchers found a way to use a nickel foil to regulate the battery's temperature during charging and ensure that it can be rapidly charged without overheating.
The fast charging will work for everything from 150 kWh batteries down to smaller batteries of 50 kWh.
The researchers hope that the new battery will speed up the transition to electric cars around the world. Since it is possible to fast-charge even smaller batteries, the actual charging time is no longer as decisive. More people can thus hopefully consider getting an electric car even if it does not have as long a range as a petrol car.
“Real fast-charging batteries would have a direct impact. "Since there are not enough raw materials to replace every car that has an internal combustion engine with an electric car with a 150 kWh battery, fast-charging is a must for electric cars to become the natural choice," said Chao-Yang Wang, a professor at Penn State and lead author of the study.
EC Power is now working on being able to start mass-producing the battery. However, when a commercial product will be available is not yet clear.
