Why lithium ion batteries fail
Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. Scientists have quantified this effect for the first time using high-resolution 3-D movies recorded using x-ray tomography at the Swiss Light Source.
