LTO Anode Active Material (Li₄Ti₅O₁₂) Powder

Overview

Lithium titanium oxide (LTO, Li₄Ti₅O₁₂) is a spinel “zero-strain” anode active material widely used for high-power and long-life lithium-ion batteries. Its Li⁺ intercalation occurs at ~1.55 V vs Li/Li⁺, which improves safety by reducing the likelihood of lithium plating during fast charge, while maintaining excellent cycling stability and rate capability.

Material options

TOB offers two research-grade LTO powder variants to match different electrode fabrication workflows:

• LTO-W (white, uncoated): carbon content 0%
• LTO-B (black, carbon-coated): carbon content 3–5% (enhanced electronic conductivity)
  
  

Key specifications (typical)

• Particle size (µm): D10 0.2–0.6; D90 ≤10
• D50 (µm): 0.7–1.5 (LTO-W); 0.8–1.6 (LTO-B)
• Purity: 99%
• Tap density: ≥0.9 g/cm³ (LTO-W); ≥1.0 g/cm³ (LTO-B)
• BET surface area: ≤16 m²/g (LTO-W); ≤6.0 m²/g (LTO-B)
• First capacity: ≥150 mAh/g; First efficiency: ≥93% (LTO-W) / ≥92% (LTO-B)
  
  

Compatibility and typical use

LTO powders are compatible with standard battery electrode processing (slurry mixing, coating, calendaring) using common binders (e.g., PVDF or water-based CMC/SBR). LTO-W typically requires added conductive carbon, while LTO-B integrates conductivity via coating—useful for high-rate testing.
