FILMIX™ – Continuous production process for lithium-ion battery slurries.

- High production speed for thin-film dispersions
- Better batteries due to highly efficient process
- Easy to assemble and clean
- Ideal for small batches right through to mass production


Bühler and PRIMIX Corporation jointly distribute the industrially proven FILMIX™ technology in Europe and the USA. The technology is used for the quasi continuous production of LIB electrode slurries. Bühler’s centers of competence, which are currently being extended, give customers the opportunity to try out the FILMIX™ technology and perform individual trials. Bühler complements this technology with it’s process engineering expertise in the dispersion of materials for battery technology.  

High production speed for thin film dispersions
The CDM™ process (Continuous Dispersion Mixing), specially developed for the production of slurries, has enabled substantial progress to be made in the manufacture of lithium-ion batteries. The linear scalability of the process is of significant importantance especially for the automobile industry.

Better batteries due to highly efficient process
The highly efficient, turbulent mixing process results in better battery qualities – for example charging/discharging behavior and lifespan – due to the homogenous dispersion of the conductive carbon in the active material of the cathode slurry.

Easy to assemble and clean
When designing the machine, care was taken to ensure that the individual components were easy to assemble and dismantle, thereby facilitating easy cleaning and maintenance.

Ideal for small batches right through to mass production
Stand-out features of the mixing process are high effectiveness combined with low material wear. The sensitive materials used are not damaged, which ensures that the quality of the end product is high. FILMIX™ machines are ideally suited to the production of small batches as well as continuous mass production processes.
