Oak Ridge National Laboratory scientists have developed a new battery technology that could double the energy density in electric cars.

Solid-state batteries are not a new idea, and researchers at ORNL previously laid the foundations for their creation and use in the 1990s .

The technology could double energy storage from the current maximum energy density of EV batteries to 500 watt-hours per kilogram, scientists say.
