Mapping Performance Variations to See How Lithium-Metal Batteries Fail
Using high-energy x-rays, scientists probed different points across a high-energy-density lithium-metal battery of interest for long-range electric vehicles and used the data to identify the main failure mechanism

UPTON, NY Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles. Using high-energy x-rays, they followed the cycling-induced changes at thousands of different points across the battery and mapped the variations in performance. At each point, they used the x-ray data

Real-Time Monitoring Tool Speeds Up Advanced Nuclear Reactor Development
Across the nation, environmentally minded scientists and engineers are leading a new generation of nuclear reactor designs. They see nuclear power as a clean, carbon-free energy source along with hydropower, wind, and solar.
Several of the innovative, next-generation reactor designs are safer, smaller, modular, and more mobile. They may power space flights, run on recycled nuclear fuel, and even act as portable generators for disaster response. One design, molten salt reactors (MSRs), are gaining momentum in the nuclear community.
But, before any of these new reactor designs become reality, they need to undergo many rounds of safety and operational testing.

PNNL Energy Sciences Center Will Help Realize Clean Energy Future
A new research facility on the Richland campus of Pacific Northwest National Laboratory (PNNL) is set to open fall 2021. The Energy Sciences Center (ESC) will feature many of PNNL’s strengths in chemistry, materials sciences, and computing in one building.
“The ESC will accelerate innovation in energy research using chemistry, materials science, and quantum information sciences supporting the nation’s climate and clean energy research agenda,” said Lou Terminello, associate laboratory director of the Physical and Computational Sciences Directorate. “This will be one of the most advanced facilities in the world designed for this type of research and will be a tremendous asset for the nation. The research that it will enable is going to play an important part in decarbonizing the energy system.”
