New Battery Design Can Charge an Electric Car in 10 Minutes

A new lithium-ion battery design makes it possible for electric vehicle drivers to charge their cars and hit the road in as little as ten minutes, according to a new study.

The quick charge gives drivers up to 200 miles per ten minute charge while maintaining 2,500 charging cycles, the researchers behind the study say. That is equivalent to over half a million miles throughout the battery’s life, a press release notes. All that happens in the time it takes you to brew a morning coffee.

Researchers say that this design could finally make electric vehicles a viable competitor for traditional vehicles. “Range anxiety” is the fear of being stranded if your electric vehicle runs out of charge which has been a common barrier to adoption for many drivers.

In the study, published on Wednesday in Joule, researchers from Penn State University describe an asymmetric approach to fast-charging batteries that mitigates the effects of natural degradation of the lithium-ion batteries. This is achieved by quickly charging at a high temperature and then storing the charge more slowly at a cooler temperature. The researchers found that this approach allowed the batteries to avoid performance loss usually created from “battery plaque,” called lithium plating or solid-electrolyte-interphase (SEI) growth, which typically grows on batteries over time when exposed to heat.

In order to charge your car in just ten minutes with these new batteries in the future though, you might have to buy a new car or at least replace the battery.

“[The car] would require a new battery with our internal heating structure built in,” Chao-Yang Wang, coauthor of the study and director of the Electrochemical Engine Center at Penn State, said in an email.
