Key Battery Processing Technologies
Hosokawa Micron and its global sister companies supply proven powder technologies for key battery manufacturing steps—from precursor drying to final coating. Whether you work with lithium-ion, LFP, solid-state or next-gen batteries, our systems offer maximum precision, process safety and uptime.
Drying Precursors for Cathode Materials
Before cathode materials or precursors such as nickel, cobalt or manganese oxides can be milled, they must be dried to specific moisture levels. For this, Hosokawa Micron offers several drying solutions, including:
- DMR flash dryer – for continuous drying of slurries and filter cakes
- Nauta® vacuum dryer – for batch drying of smaller quantities
- CPD conical paddle dryer – for difficult volatiles and ultra-low moisture levels
Ultra‑Fine Milling Solutions for Battery Materials
To maximise battery performance—including faster charging, longer lifetime and higher usable capacity—active materials must be ultra-fine milled. This creates a narrow particle size distribution and increases surface area, both of which are essential for optimal electrochemical behaviour.
Hosokawa offers two key milling solutions widely used in the battery industry:
- ACM air classifying mill – precise particle size cut-off with built-in classifier
- AFG fluidised bed jet mill – contamination-free, high-efficiency micronisation
Both systems are ideal for processing cathode materials such as lithium cobalt oxide or manganese-based precursors, as well as anode materials including graphite and silicon.
Graphite Spheroidisation for Higher Tap Density
Because of its naturally flaky structure and low bulk density, graphite must be spheroidised—rounded into compact shapes—to increase its packing efficiency and wettability, both of which are essential to battery capacity. Hosokawa Alpine offers two machines for rounding synthetic graphite and natural graphite:
- ZPS classifier mill – for spheroidising synthetic graphite
- APR particle rounder – for rounding natural graphite
High-Shear Mixing and Coating
High-shear mixing is essential for improving flow properties, reducing agglomeration, and applying uniform coatings to battery precursors. Hosokawa offers both batch and continuous solutions, tailored to your material behaviour and process requirements, including:
- Cyclomix – high-shear mixer
- Modulomix – continuous mixer
- Nobilta – super-high-shear mixer
- Mechanofusion – ultra-high-shear mixer
All mixers and mills are available with wear-resistant coatings for purity-critical processes.
