文摘
- •
3D reconstruction of lithium-ion battery cathodes using FIB-SEM was achieved.
- •
The particle size distribution of the cathodes before and after cycling was analyzed.
- •
The connectivity between active material and carbon-doped binder was evaluated.
- •
Cycling-induced detachment between active particles and binder was quantified.
