Fumed Titanium Dioxide Unlocks Safer Longer Lasting Batteries

Overview of Fumed Titanium Dioxide

Fumed Titanium Dioxide (nano-TiO₂) is a high-purity white nanopowder produced by the flame hydrolysis process. As a critical raw material for lithium-ion batteries, it offers unique advantages as a cathode additive, including large lithium intercalation capacity, low energy consumption, high specific capacity, excellent cycling stability, and environmental friendliness.

In lithium-ion battery applications, nano-TiO₂ enhances rate capability and cycling stability, enables fast charge-discharge performance, and exhibits excellent Li⁺ deintercalation reversibility. It reduces capacity fade, improves electrochemical performance, and increases the initial discharge specific capacity of battery materials. Additionally, its photostability makes it a key material for photovoltaic solar energy conversion cells.

Features of Fumed Titanium Dioxide

• High Purity (≥99.9%) – Ultra-high purity ensures minimal impurity interference in battery systems, preventing unwanted side reactions.
• Multiple Crystal Phases Available – Available in both Rutile and Anatase phases, each optimized for specific battery applications:
  • Rutile (TR-T30D): Enhances electrochemical stability and cycling performance.

5 FAQs about Fumed Titanium Dioxide

1. What is the difference between Rutile and Anatase nano-TiO₂ for battery applications?
Rutile (TR-T30D) is primarily used to enhance electrochemical stability and cycling performance of cathodes. Anatase (TR-TA30D) is preferred for lithium titanate synthesis and offers higher specific surface area (60–90 m²/g), which can improve capacity and reaction kinetics.

2. How much nano-TiO₂ should be added to cathode materials?
Typical addition levels range from 0.5% to 5% by weight, depending on the cathode chemistry and desired performance improvements. We recommend optimizing dosage through small-scale testing.

3. How does nano-TiO₂ improve battery safety?
Nano-TiO₂ reduces lithium dendrite formation by providing a more stable electrode interface and reducing polarization. Its structural stability also minimizes internal short-circuit risks.

4. Can this product be used in sodium-ion batteries?
Yes. Anatase-phase nano-TiO₂ has shown promise in sodium-ion battery applications due to its open channel structure that accommodates larger Na⁺ ions.

5. What is the shelf life of fumed TiO₂?
When stored in a dry, sealed container away from moisture, the product maintains its properties for up to 24 months.
