Short Description

The mixing step involves carefully combining active materials, conductive additives, binders, and a solvent to produce a homogeneous, viscous slurry with precise rheological properties, ready for coating. Multiple process sequences are used, typically involving dry mixing followed by wet dispersing, though the exact order may vary depending on the electrode formulation, mixing technology and performance requirements. 

The resulting slurry must meet strict consistency and stability criteria to ensure uniform coating. Transport to the next sub-process, Coating, is normally done via sealed containers or piped systems, often under controlled environmental conditions to prevent contamination or moisture uptake. 

Inputs

Active cathode materials (e.g. LFP, NMC)
Active anode materials (e.g. Graphite, SiOx)
Conductive additives (e.g. C65, Dispersants)
Binders (e.g. Cathode - PVDF, Anode - CMC, SBR)
Solvents (e.g. NMP, DI Water)

Outputs

Slurry
