- Coating (thickness, layer density)
- Spatial distribution of active material in through-plane direction
- Drying behavior (diffusion paths, porosity)
- Calendering behavior
- Post-Calendering drying
- Filling with Electrolyte
- Coating (thickness, layer density)
- Mixing quality affects on battery performance
- Energy density
- Defects (particle breakage)
