Production of Lithium Batteries Application-specific Mixer for Battery Masses
In the production of lithium batteries extremely high quality demands are placed on the preparation of the required raw materials. Lödige has addressed this challenging process-technical task with a special version of the proven Ploughshare mixer.
The mixing drum has a ceramic lining, but due to their more complex geometry a different covering was required for the mixing elements. Together with the mixer shaft and choppers, they were provided with a thin, but extremely tough ceramic coating.
The coatings can be adjusted to the respective application, adds the firm. Standard coating materials are based on aluminium oxide or tungsten carbide. In any event, these wear-resistant, hard coatings are designed for long-term operation.
Because the battery masses contain toxic and carcinogenic components such as cobalt, uncontrolled spillage of the fine powdery substance must be strictly avoided. In particular, the shaft seal is often a weak point. However, modern and application-specific sealing systems guarantee a seal that is superior to a classical stuff box packing.
According to the company, the Ploughshare mixer achieves homogeneous mixing of the cathode masses in the shortest possible time. This is essential for the consistent, reproducible quality of these high-tech materials.
