1. Why is a controlled atmosphere necessary for cathode material production?
Lithium cathode materials are sensitive to oxygen and moisture. A controlled atmosphere (N₂, Ar) prevents unwanted reactions, ensuring high purity and electrochemical performance.
2. What temperature range does the roller kiln support?
Typically 800°C–1200°C, adjustable based on material requirements (e.g., LFP ~800°C, NMC ~900°C–1000°C).
3. How does the roller kiln improve production efficiency?
Its continuous operation eliminates batch processing delays, increasing throughput while maintaining consistency.
4. Can the kiln handle different cathode materials?
Yes, with programmable temperature profiles and gas settings, it accommodates LFP, NMC, LCO, and other cathode chemistries.
5. What maintenance is required?
Regular inspection of heating elements, gas seals, and rollers ensures long-term reliability.
The Industrial Roller Kilnis a vital solution for lithium battery cathode production, offering high-temperature stability, controlled atmosphere processing, and continuous operation.
