Abstract
The electrochemical degradation of Li-ion batteries occurs over different spatial and temporal scales. This work demonstrates how operando synchrotron X-ray diffraction can be used to study degradation in Li-ion battery materials by mapping component-specific crystallographic structure evolution across a single-layer pouch full cell in real-time, enabling quantification of structural degradation processes in Li-ion battery cells from the atomic to macroscopic scale.
