Product Applications
1. High-purity gamma-phase nano-alumina is used as a coating for lithium battery electrodes, providing thermal insulation and electrical insulation to enhance safety performance.
2. Doping high-purity gamma-phase nano-alumina into lithium cobalt oxide can form a solid solution, stabilize the crystal lattice, and improve rate performance and cycling performance.
3. Coating lithium cobalt oxide with high-purity nano-alumina can improve thermal stability, enhance cycling performance and overcharge resistance, suppress oxygen generation and the decomposition of LiPF6, prevent direct contact between LiCoO2 and the electrolyte, reduce the loss of electrochemical specific capacity, and thereby increase the electrochemical specific capacity of LiCoO2.
4. The doping of aluminum ions in nano-alumina can increase the battery voltage and enhance the safety of battery usage.
5. High-purity nano-alumina is used to modify spinel lithium manganate materials, resulting in batteries with large reversible capacity.
6. Petrochemical Industry: Catalysts, catalyst carriers, and automotive exhaust purification materials.
7. Polishing Materials: Sub-micron/nano-scale grinding materials, grinding of monocrystalline silicon wafers, precision polishing materials.
Packaging and Storage
This product is packaged in inert gas-filled plastic bags and should be stored sealed in a dry, cool environment. It should not be exposed to air to prevent moisture-induced oxidative agglomeration, which may affect dispersion performance and usage effectiveness. The packaging quantity can be provided according to customer requirements, with sub-packaging available.
