Product Features
Boehmite is mainly used as a coating for lithium-ion battery cell separators and electrodes.
Coated on the battery separator: improves heat resistance and puncture resistance, enhancing the safety performance of lithium batteries.
Coated on battery electrodes: prevents burrs generated during electrode slitting from piercing the separator, improves safety, optimizes the production process, and increases energy density.

FAQ
Q: What after-sales services do you provide?
A: We offer end-to-end support dedicated to your success. Our specialized team provides comprehensive services ranging from expert technical consultation and rapid quality resolution to full batch traceability. We also streamline return/exchange processes and optimize future orders to ensure continuous improvement in our partnership.
Q: Is your Boehmite suitable for transparent ceramic applications?
A: Absolutely. Due to its high transparency and fine particle size, our Boehmite is an ideal precursor for producing high-quality transparent alumina ceramics used in lighting and optics.
Q: Are your products compliant with international environmental standards (e.g., RoHS, REACH)?
A: Yes, all our Boehmite products are fully compliant with RoHS, REACH, and other relevant international environmental and safety regulations.
Q: How should Boehmite powder be stored to maintain quality?
A: It should be stored in a cool, dry, and well-ventilated warehouse, away from moisture and direct sunlight. Proper sealing is crucial as Boehmite can absorb moisture from the air, affecting its dispersion.
