Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling

open access: yesAdvanced 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

A Solvent‐Free, Dry‐Processed Li‐Ion Battery Enabled by Dual Binders and Nanostructured Aluminum Current Collectors

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐binder dry‐processed electrode (DB‐DPE) combining PTFE and PVDF with a nanostructured Al current collector (NSA) forms a mechanically interlocked interface that significantly improves adhesion and reduces interfacial resistance. With an active material content as high as 96 wt.%, the NSA‐based DB‐DPE enables high‐mass‐loading operation (12.5 mAh
