Researchers used a Lawrence Berkeley National Laboratory, or Berkeley Lab, X-ray device to gain insight into the process by which lithium-ion batteries, such as those found in electric vehicles, lose battery life over time. These findings point toward a key to designing electric vehicles that charge much faster and maintain battery health. The study, a collaboration between Stanford University, the Massachusetts Institute of Technology and Toyota Research Institute, used imaging technology at Stanford University and UC Berkeley, as well as novel machine learning techniques to understand how f...

SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging Scientists have made a major advance in harnessing machine learning to accelerate the design for better batteries. Instead of using machine learning just to speed up scientific analysis by looking for patterns in data—as typically done—the researchers combined it with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries. It was the first time this approach—known...

But the finished material didn't behave as they expected: As one version of the catalyst went about its work, the top-most layer of atoms rearranged to form a new pattern, as if th...
