Synthetic Graphite Powder Anode Material for High End Lithium Ion Batteries

Product Overview

This high-purity synthetic graphite powder is an advanced anode active material engineered specifically for high-energy-density and long-cycle lithium-ion battery architectures. Manufactured through high-temperature graphitization and precision particle classification, the material exhibits an exceptional degree of graphitic ordering with an interlayer spacing of 3.358 ± 0.003 Å. This optimized microstructure enables fast lithium-ion intercalation and de-intercalation kinetics while maintaining structural stability across prolonged charge-discharge cycles.

Designed to satisfy the stringent requirements of modern electrochemical energy storage R&D and commercial pouch, prismatic, and cylindrical cell fabrication, this active material demonstrates superior initial coulombic efficiency exceeding 92.0% and a reversible first discharge capacity of at least 360 mAh/g. It is ideally suited for researchers and cell manufacturers developing high-rate capability power batteries, premium consumer electronic cells, and next-generation energy storage systems.

Rigorous chemical purification and physical processing ensure exceptionally low levels of residual ash (≤0.1%), moisture (≤0.2%), and magnetic metallic impurities (Fe ≤50 ppm). This clean chemical profile minimizes irreversible side reactions during initial solid electrolyte interphase (SEI) formation, suppressing self-discharge rates and gassing in finished cells to guarantee outstanding operational safety and long-term reliability.

Key Features

• High Reversible Discharge Capacity: Achieves a first discharge capacity of ≥360 mAh/g, approaching the theoretical limit of graphite to maximize gravimetric energy density in high-end lithium-ion cell designs.
• High Initial Coulombic Efficiency: Delivers an initial charge-discharge efficiency of ≥92.0%, substantially lowering first-cycle active lithium consumption and reducing overall cathode overbalancing requirements.
• Optimized Interlayer Crystal Structure: Features a tightly controlled graphitic interlayer spacing of d002 = 3.358 ± 0.003 Å, facilitating rapid Li-ion transport pathways and reducing structural degradation during continuous high-rate cycling.
• Controlled Particle Size Distribution: Engineered with a balanced particle grading (D10: 8.0–12.0 µm, D50: 18.0–22.0 µm, D90: 35.0–41.0 µm) that ensures high slurry packing density, excellent slurry rheology, and uniform electrode coating thickness.
• Superior Tap Density and Packing Performance: Exhibits a high tap density of ≥0.80 g/cm³, allowing for optimal calendering press density and improved volumetric capacity without inducing excessive particle fracture.
• Tailored Specific Surface Area: Maintains a moderate BET specific surface area of 2.0–5.0 m²/g, balancing rapid electrolyte wetting and high interfacial rate kinetics against parasitic electrolyte decomposition.
• Ultra-Low Metallic Impurity Content: Contains trace iron levels below 50 ppm to prevent internal micro-short circuits, eliminate localized current concentration, and enhance cell safety throughout extended service life.
• Minimal Moisture and Volatile Residues: Processed to maintain moisture content at ≤0.2% and ash residue at ≤0.1%, ensuring high slurry stability, strong binder adhesion, and suppression of gas generation during formation.
