Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling
Advanced Functional Materials, EarlyView.This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed
