T Natural Graphite Powder

Overview

Graphite Anode Active Material (C) Powder is a high-purity natural graphite designed for use as a negative electrode material in lithium-ion batteries. During battery operation, lithium ions reversibly intercalate into the layered graphite structure (d002 ≈ 3.358 Å), forming LixC₆ phases during charging and de-intercalating during discharge. This well-defined interlayer spacing enables stable lithium storage with excellent reversibility and low polarisation.

The Graphite-T grade features controlled particle size distribution and compact morphology, supporting high tap density and uniform electrode coating behaviour. These properties are critical for achieving consistent electrochemical performance and long cycle life in laboratory-scale and pilot-scale battery research.

Key Material Features and Specifications

• Particle size distribution:
• D10: 8.0–12.0 µm
• D50: 16.0–21.0 µm
• D90: 27.0–36.0 µm
• First discharge capacity: ≥ 360 mAh/g
• First discharge efficiency: ≥ 93%
• Tap density: ≥ 0.85 g/cm³
• Specific surface area (SSA): ~3.3 m²/g
• Moisture content: ≤ 0.2%
• Ash content: ≤ 0.1%
• Magnetic impurities (Fe, Cr, Ni, Zn): ≤ 0.10 ppm
• Iron (Fe): ≤ 50 ppm

Low impurity levels minimise parasitic reactions, improving coulombic efficiency and cycle stability.
