Off to the races with new battery coating tech

07 June 2016

Drivers of Formula E cars may soon no longer have to change cars midway through the race, thanks to a new battery coating technology.

The technology was developed by XALT Energy of Michigan and Oak Ridge National Laboratory

By depositing a nanoscale layer of alumina on oxide cathodes, researchers have increased battery energy density by up to 30 percent. “This work highlights the dominant effects of surface chemistry on active material performance,” the authors wrote in their paper published in Scientific Reports. 

ORNL co-author David Wood III noted that the results are encouraging not only for drivers of race cars but also for passenger electric vehicle manufacturers and consumers. This new technology could be on the racetrack as early as October 2017.
