When electricity flows through a battery, the materials inside it gradually wear down. The physical forces of stress and strain also play a role in this process, but their exact effects on the battery’s performance and lifespan are not completely known.
A team led by researchers at the Department of Energy’s Oak Ridge National Laboratory developed a framework for designing solid-state batteries, or SSBs, with mechanics in mind. Their paper, published in Science, reviewed how these factors change SSBs during their cycling.
