Product Applications

1. High-purity gas-phase nano alumina is used in lithium battery separator materials to improve high-temperature resistance and safety; also used in lithium battery anodes to enhance conductivity and reversible discharge capacity; used for cathode coating to improve temperature resistance and safety; used as a coating for lithium battery electrodes to provide thermal insulation and insulation, improving safety performance;

2. Doping aluminum from high-purity gas-phase nano alumina into lithium cobalt oxide can form a solid solution, stabilize the crystal lattice, and improve rate performance and cycle performance;

3. Coating lithium cobalt oxide with high-purity nano alumina can improve thermal stability, cycle performance, and overcharge resistance; it prevents the generation of oxygen and decomposition of LiPF6, avoids direct contact between LiCoO2 and electrolyte, reduces electrochemical specific capacity loss, thereby enhancing the electrochemical specific capacity of LiCoO2;

4. Doping with aluminum ions from nano alumina can increase battery voltage and improve battery safety;

5. High-purity gas-phase nano alumina is used to modify spinel lithium manganate materials, producing batteries with large reversible capacity;

6. Petrochemical industry: catalysts, catalyst carriers, and automotive exhaust purification materials;

7. Polishing materials: submicron/nanoscale abrasive materials, polishing of monocrystalline silicon wafers, and precision polishing materials.

Packaging and Storage

This product is packaged in plastic bags inside, with outer carton packaging. It should be stored sealed in a dry, cool environment, not exposed to air, to prevent moisture-induced agglomeration, which affects dispersion performance and usage. Packaging quantity can be customized according to customer requirements, with subdivision available.
