Nano Aluminum Oxide for Lithium Battery Materials

Overview of Nano Aluminum Oxide

Nano Aluminum Oxide (Al₂O₃) for lithium batteries is a high-performance nanopowder engineered specifically for battery and battery material applications. Utilizing advanced nano-processing technology, our product features uniform and fine particle size, exceptionally high purity, and superior surface properties. It is widely used in lithium batteries, alkaline batteries, solar cells, and other energy storage systems to enhance energy density, improve safety performance, and support energy-saving and environmentally friendly initiatives.

Features of Nano Aluminum Oxide

• Excellent thermal insulation and electrical insulation – When used as an electrode coating, it effectively isolates heat and prevents short circuits, significantly improving battery safety.
• Enhanced structural stability – Doping aluminum ions into lithium cobalt oxide (LiCoO₂) forms a solid solution that stabilizes the crystal lattice, boosting rate performance and cycle life.
• Superior surface protection – Coating LiCoO₂ with nano alumina improves thermal stability, overcharge resistance, and cycling performance. It suppresses oxygen generation and inhibits the decomposition of LiPF₆, while also preventing direct contact between the cathode material and the electrolyte, thereby reducing electrochemical capacity loss.
• Increased operating voltage – The introduction of aluminum ions raises the battery’s voltage, contributing to safer operation.
• Improved reversible capacity – When applied to modified spinel lithium manganese oxide (LiMn₂O₄) materials, nano alumina helps produce batteries with larger reversible capacity.

FAQs of Nano Aluminum Oxide

1. What is the difference between the TR-L500G and TR-L30D models?
TR-L500G is an α-phase alumina with a larger particle size (0.5 μm) and ultra-high purity (99.999%), primarily used for separator coatings. TR-L30D is a γ-phase nano alumina with a smaller particle size (30 nm) and higher surface area, designed for cathode material doping and additive applications.

2. How does nano alumina improve battery safety?
It acts as both a thermal barrier and an electrical insulator, reducing the risk of thermal runaway and internal short circuits, especially when applied as a separator or electrode coating.

3. Can this product be used with other battery chemistries?
Yes, besides lithium-ion batteries, it is also suitable for alkaline batteries, solar cells, and other advanced energy storage systems where enhanced safety and stability are required.

4. What purity levels are available?
We offer 99.999% purity (TR-L500G) for high-end separator applications and 99.99% purity (TR-L30D) for cathode modification, both ensuring minimal impurities for consistent performance.

5. How should the product be stored?
Store in a cool, dry place in the original sealed packaging. Avoid exposure to moisture and direct sunlight to maintain product quality.
