Carbon Coated and Uncoated LTO Lithium Titanate Powder Li4Ti5O12 LiTiO Battery Anode Material

Product Overview

This premium-grade lithium titanate (Li4Ti5O12 / LTO) powder is an advanced spinel-structured anode active material engineered for high-safety, ultra-long cycle life, and high-rate electrochemical energy storage systems. Available in both uncoated high-purity crystalline form and optimized surface carbon-coated formulations, this active material addresses the demanding trade-offs of modern cell engineering. By delivering a stable operating potential of approximately 1.55 V versus Li/Li+, this powder virtually eliminates lithium dendrite formation, offering structural zero-strain characteristics during continuous lithium insertion and extraction cycles.

Designed for demanding industrial, transportation, and research applications, this anode material is widely deployed in grid-scale battery energy storage systems (BESS), electric public transit, automated guided vehicles (AGVs), hybrid supercapacitors, and specialized power supplies operating under severe environmental conditions. While conventional graphite anodes experience volumetric expansion and safety challenges during high-rate charging, this material maintains pristine structural integrity, making it an ideal choice for fast-charging and safety-critical battery architectures.

Every batch is processed under rigorous quality control standards to ensure tight particle size distributions, exceptional chemical purity, and superior batch-to-batch consistency. Whether utilized in pilot-line cell prototyping or full-scale industrial manufacturing, this material provides dependable electrochemical performance, excellent low-temperature kinetics, and uncompromised operational reliability across thousands of full-depth cycles.

Key Features

• Zero-Strain Spinel Crystal Structure: The lithium titanate crystalline framework experiences near-zero lattice volume change (<1%) during lithium-ion intercalation and de-intercalation, preventing electrode pulverization and supporting extended operational lifespans exceeding tens of thousands of cycles.
• Carbon-Coated Conductivity Optimization: The carbon-coated variant features a uniform 3–5% surface conductive carbon network that bridges particle contact resistance, dramatically enhancing electronic conductivity across the 2.98 eV bandgap semiconductor matrix for superior high-rate charge and discharge capability.
• Dendrite-Free High Operational Potential: Operating at a flat voltage plateau of ~1.55 V (vs. Li/Li+), this material operates safely above the lithium reduction potential, preventing metallic lithium plating even during high-C-rate fast charging and sub-zero temperature operation.
• Narrow Particle Size Distribution: Precision micronization yields tightly controlled D10 (0.2–0.6 µm), D50 (0.7–1.6 µm), and D90 (≤10 µm) particle fractions, facilitating rapid solid-state lithium-ion diffusion pathways and uniform current density distribution within composite electrode matrices.
• High Tap Density and Packing Efficiency: Engineered morphology provides tap densities reaching ≥0.9 g/cm³ for uncoated grades and ≥1.0 g/cm³ for carbon-coated grades, maximizing volumetric energy efficiency and active material loading during doctor-blade or slot-die roll-to-roll electrode coating.
• Tailored Specific Surface Area: Specific surface area is controlled to ≤16 m²/g for uncoated and ≤6.0 m²/g for carbon-coated formulations, mitigating parasitic electrolyte side reactions, reducing initial gas evolution, and delivering high first-cycle Coulombic efficiencies (≥92–93%).
• Strict Contaminant and Foreign Matter Screening: Every lot undergoes rigorous 200-mesh sieve classification and automated analytical verification to eliminate magnetic impurities and oversize agglomerates, guaranteeing high dielectric integrity and preventing internal cell micro-shorts.
