| Specification | Typical Range | Notes |
|---|---|---|
| Purity | 95% - 99.5% | Higher purity for battery grade |
| Particle Size | 5 - 50 microns | Depends on application |
| Bulk Density | 0.4 - 0.8 g/cm³ | Affects handling and packing |
| Conductivity (Electrical) | ~10,000 S/m | Critical for electrode use |
| Moisture Content | Low moisture prevents clumping |
| Supplier | Minimum Order (tons) | Typical Purity | Sustainability Certifications | Global Shipping |
|---|---|---|---|---|
| GraphCo Ltd. | 5 tons | 98% | ISO 14001 | Yes |
| NanoCarbon Corp. | 1 ton | 99.5% | EcoVadis Gold | Limited |
| PureGraphite Inc. | 10 tons | 97% | None | Yes |
Key considerations include purity levels, particle size distribution, supplier reliability, and sustainability certifications. You also want to confirm shipping terms and storage conditions to maintain powder integrity.
Graphite powder serves as the anode material in lithium-ion batteries due to its excellent electrical conductivity and stability. Bulk supply ensures manufacturers can meet large-scale production needs while maintaining consistent quality.
Many suppliers offer customization options, such as tailored particle sizes or impurity levels, to fit applications ranging from lubricants to refractory products. Always discuss your requirements early with vendors.
Store it in dry, cool environments in sealed containers to prevent moisture ingress and clumping. Avoid exposure to contaminants or extreme temperatures to maintain product quality.
Synthetic graphite offers higher purity and greater uniformity but often at a higher cost. It’s ideal for specialty applications, while natural graphite powder provides a cost-effective option for large-volume, standard uses.
