Billions of tiny particles packed into rechargeable lithium-ion battery electrodes are responsible for storing charge and making it available when it’s needed to do work. X-ray movies of this process show the particles absorbing and releasing lithium ions as the battery charges and discharges. Analyzing every pixel of those movies with computer vision has revealed physical and chemical details of battery cycling that could not be seen before.

Researchers developed a new battery material called disordered rock salt (DRX) that could pave the way for replacing gasoline vehicles with electric vehicles at a faster rate. DRX cathodes could be ready to commercialize in just a few years.

With funding from DOE’s BRaVE initiative, the Berkeley Lab-led EMERGE project will expand the capabilities of ExaEpi, an exascale-ready epidemiological agent-based model to target six diseases.

Experts at Berkeley Lab finished winding more than 2000 kilometers of superconducting wire into cables for new magnets that will help upgrade the Large Hadron Collider and the search for new physics.

Researchers from Berkeley Lab are co-leading a project to explore the creation of a Direct Air Capture (DAC) facility that uses cutting-edge technologies to remove carbon dioxide from the atmosphere in California’s Southern San Joaquin Valley.

To mitigate the risks of living in extreme heat, scientists have developed policy recommendations and free toolkits in collaboration with city, state, and federal agencies and nonprofits to help disadvantaged communities adapt and thrive in a warming climate.

A team of Berkeley Lab researchers has recently demonstrated a more effective technique for creating quantum emitters using pulsed ion beams, which could lead to their use in a quantum internet and for sensing radiation. Quantum emitters are atomic-scale defects in semiconductor materials that can emit single photons of fixed wavelength or color and allow photons to interact with electron spin properties in controlled ways.

Researchers at the Center for High Precision Patterning Science (CHiPPS) in Berkeley, California, could help chip manufacturers make smaller, more powerful microchips and mitigate supply chain disruptions by helping the U.S. design and manufacture the world’s most advanced chips domestically. In a new Q&A, microelectronics expert and CHiPPS Director Ricardo Ruiz shares his perspective on keeping pace with Moore’s Law in the decades to come through a revolutionary technique called extreme ultraviolet lithography.

The Advanced Quantum Testbed (AQT) at Berkeley Lab celebrated the first five years of operations and its renewal with a two-day hybrid summit in May 2023, bringing together staff, alums, testbed users, and colleagues. The summit was a unique opportunity to come together, share the latest experimental breakthroughs and lessons learned, and jointly plan the path forward for AQT.
