Multi‐Faceted Binder Enhancement via Slurry‐Applicable Thiol‐Ene Click Chemistry for Low‐Pressure‐Operable All‐Solid‐State Batteries

Advanced Functional Materials, EarlyView.
Cross‐linked binders with enhanced resiliencies under low operating pressures are designed via in situ thiol‐ene click reactions within slurries. Cross‐linking improves the Young's moduli and elasticities of the styrene‐butadiene rubber binders, effectively mitigating interparticle delamination within the composite cathodes induced by volumetric ...

Deciphering the Interplay Between Wetting and Chemo‐Mechanical Fracture in Lithium‐Ion Battery Cathode Materials

Advanced Functional Materials, EarlyView.
The fundamental intricate couplings between electrolyte wetting and fracture evolution are investigated in large single‐crystal V2O5 samples using both experimental techniques and simulations. Both approaches reveal consistent fracture patterns and lithium distribution concentration maps influenced by the wetting mechanism.

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
