Lithium-ion battery material breaks barrier on fast charging

Posted by in categories: energy, sustainability, transportation

Researchers at the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville, discovered a key material needed for fast-charging lithium-ion batteries. The commercially relevant approach opens a potential pathway to improve charging speeds for electric vehicles.

Lithium-ion batteries, or LIBs, play an essential role in the nation’s portfolio of . Most hybrid electric and all– use LIBs. These offer advantages in reliability and efficiency because they can store more energy, charge faster and last longer than traditional lead-acid batteries. However, the technology is still developing, and fundamental advances are needed to meet priorities to improve the cost, range and charge time of electric-vehicle batteries.

“Overcoming these challenges will require advances in materials that are more efficient and that are scalable to industry,” said ORNL Corporate Fellow and corresponding author Sheng Dai.
