  • Method opens a window on how stress and strain affect battery performance

    Illinois professors Nancy Sottos and Andrew Gerwith developed a method to comprehensively measure the mechanical stress and strain in lithium-ion batteries. It revealed a point of stress in charging that, if addressed through new methods or materials, could lead to faster-charging batteries.
