About this material
Artificial graphite is produced by graphitising petroleum coke or needle coke at temperatures above 2800 °C. The resulting material has a highly ordered layered structure, low surface area and a surface chemistry that forms a compact, stable SEI in the first cycles. Compared with natural graphite it offers better rate capability and more consistent batch-to-batch behaviour, at a higher cost per kilogram.
This grade is intended for negative electrode preparation in NMP-free water-based systems using SBR and CMC. Its particle size distribution is controlled to balance rate performance against slurry viscosity and coating quality — finer powders improve kinetics but raise binder demand and increase the risk of electrode cracking during drying.
Documentation, controls and care
Quality controls
- Certificate of analysis per batch
- Moisture by Karl Fischer
- Magnetic impurity screening
- Tap and pressed density verification
Handling & storage
- Store dry below 30 °C in sealed packaging.
- Avoid prolonged exposure to humid air — graphite adsorbs moisture readily.
- Vacuum dry at 80–100 °C before use in moisture-sensitive cells.
