Scientists working at the Oak Ridge National Laboratory (ORNL) have developed a new kind of solid-state battery technology that could double the energy density in electric cars.
The distance electric vehicles (EVs) can travel between charges — known as their range — has been on a steady upward curve for the past decade, tripling from 80 miles (129 kilometers) in 2010 to 220 miles (354 km) in 2021.
