Background: High Standard challenge in Lithium Battery Material Processing
With the rapid development of electric vehicles, energy storage systems, and portable electronics, the lithium battery industry has entered a stage of explosive growth.
In this field, raw material preparation is critical. Key materials like:
- Cathode materials（LiFePO₄, NCM, LCO）
- Anode materials（natural graphite, synthetic graphite, silicon-carbon composites））
- Conductive additives（carbon black, CNTs）
- Solid electrolytes（sulfides, oxides）
…all require precise powder processing technology — from ultra-fine grinding to particle classification — to meet the demanding requirements for battery performance and safety.
Core Equipment for Lithium Battery Materials
Jet Mill
Used for ultra-fine, contamination-free grinding of materials like silicon-carbon, graphite, and ceramic-based solid electrolytes.
Key Features | ：
- The final particle size can reach D50: 2-5 microns
- No introduction of grinding media and impurities
- Suitable for heat-sensitive materials and high-purity requirements
Air Classifier
Realize precise control of particle size distribution, suitable for battery materials with strict requirements for particle size distribution.
Key Features | :
- Adjustable classification range from 1μm to 40μm
- High classification efficiency and product yield
- Can be integrated with jet mills or mechanical mills
Impact Mill
Used for large-scale production of materials like graphite flakes or certain cathode raw materials.
Key Features | ：
- High throughput
- Adjustable output fineness
- Lower energy cost compared to jet mills
Ultrafine Roller Mill
Efficient grinding for carbon black, conductive agents, and other soft to semi-hard materials.
Application Examples
- Silicon-based anode grinding: Jet mill + air classifier, achieves D50 = 3μm
- Solid-state electrolyte treatment: Jet mill for ceramic powders, no contamination
- Graphite shaping and size control: Impact mill + air classifier
Outlook: Equipment Demand Driven by Battery Industry Expansion
With the continuous improvement of battery material properties, equipment also needs to meet the demand for higher precision, cleanliness, and scale-up capability.
High-efficiency, modularization, and customizable grinding and classification systems are becoming the mainstream choice for global battery material processors.
