Synthetic Graphite (battery anode grade)

Description

1. Product Overview

This product is a highly crystalline, battery-grade synthetic graphite manufactured through precision graphitization of carbon precursors. It is primarily used as the active anode material in lithium-ion batteries for electric vehicles (EVs) and grid-scale energy storage systems (ESS). The key value proposition is its consistent electrochemical performance, high tap density, and low impurity profile, which directly enhance battery energy density and lifespan. Strategically, it mitigates supply chain risks associated with natural graphite refining, offering a scalable, Western-friendly source of anode material critical for the global energy transition.

2. Key Specifications & Technical Characteristics

• Chemical composition: >99.95% total carbon content; ash ≤0.02%; Fe ≤20 ppm; magnetic particles ≤5 ppb

• Purity level: Battery anode grade (Grade SG-BA99.95)

• Physical characteristics: Black, odorless powder; D50 = 14–18 µm; tap density = 0.9–1.1 g/cm³; BET surface area = 1.5–3.0 m²/g; specific capacity = 350–365 mAh/g

3. Core Industrial Applications

• Electric vehicle (EV) battery manufacturing: Serves as the premium anode active material for high-energy 2170, 4680, and pouch cells. Outperforms natural graphite in fast-charging (≤15 min to 80% SOC) and cycle life (>2,000 cycles to 80% capacity retention).

• Grid-scale energy storage systems (ESS): Enables long-duration batteries requiring minimal self-discharge and superior thermal stability. Reduces cell formation costs due to lower irreversible capacity loss (≤6%).

• Consumer electronics batteries: Provides consistent intercalation behavior for thin prismatic cells, eliminating lithium plating risks seen with lower-grade synthetic or natural blends.
