Electric vehicles can drive longer distances if their lithium-ion batteries deliver more energy in a lighter package.

In response to a renewed international interest in molten salt reactors, researchers from the Department of Energy’s Oak Ridge National Laboratory have developed a novel technique to visualize molten salt intrusion in graphite.
As current courses through a battery, its materials erode over time. Mechanical influences such as stress and strain affect this trajectory, although their impacts on battery efficacy and longevity are not fully understood.
In 2023, the National School on X-ray and Neutron Scattering, or NXS, marked its 25th year during its annual program, held August 6–18 at the Department of Energy’s Oak Ridge and Argonne National Laboratories.
Quantum computers process information using quantum bits, or qubits, based on fragile, short-lived quantum mechanical states.
Since its inception in 2010, the program bolsters national scientific discovery by supporting early career researchers in fields pertaining to the Office of Science.
ORNL scientists found that a small tweak created big performance improvements in a type of solid-state battery, a technology considered vital to broader electric vehicle adoption.
Ho Nyung Lee, a condensed matter physicist at the Department of Energy’s Oak Ridge National Laboratory, has been elected a Fellow of the Materials Research Society.
For as long as he could remember, Brenden Ortiz wanted to do only one thing. “My childhood dream was to be a scientist. All I wanted to do was tinker in a lab like a pure scientist,” Ortiz said.
Warming a crystal of the mineral fresnoite, ORNL scientists discovered that excitations called phasons carried heat three times farther and faster than phonons, the excitations that usually carry heat through a material.
