Raw Materials – Graphite

1) Material Properties

Crystal Structure: Hexagonal layered structure, resulting in excellent electrical conductivity (resistivity 0.5-5×10⁻⁶ Ω·m) and thermal conductivity (300-1500 W/m·K in the direction parallel to the layers).

Chemical Stability: High-temperature resistance (sublimation point 3650°C), corrosion resistance, and stable performance in an inert environment.

Mechanical Properties: Soft texture (Mohs hardness 1-2), yet strong interlayer bonding, allowing for processing into high-purity thin sheets.

2) Key Applications

Electrode Materials: Lithium battery anodes (energy density ≥350 mAh/g), fuel cell bipolar plates.

Heat Dissipation Components: Highly thermally conductive graphite film (perpendicular thermal conductivity 800-1800 W/m·K) for chip cooling.

Conductive Fillers: Conductive inks for flexible circuit boards, antistatic packaging materials.
