Battery Binder PVDF-9300 – High-Purity Polyvinylidene Fluoride for Li-Ion Battery Cathode
PVDF (Polyvinylidene fluoride) is a high-performance polymer binder widely used in the preparation of lithium-ion battery cathodes. It serves as a critical component that bonds the cathode active material and conductive additives to the current collector, ensuring mechanical integrity and electrochemical performance of the electrode.
PVDF-9300 is a battery-grade PVDF binder specifically designed for lithium-ion battery cathode applications. It offers excellent chemical resistance, thermal stability, and adhesion properties, making it ideal for high-performance battery electrode formulations.
Key Features:
- High Purity: Consistent quality with low impurity levels for reliable electrochemical performance.
- Excellent Thermal Stability: Thermal decomposition temperature ≥380°C, suitable for battery processing and operation.
- Controlled Water Content: ≤0.10% moisture content prevents slurry instability and electrode defects.
- Optimal Molecular Weight: Approximately 1,000,000 molecular weight provides balanced binding strength and slurry processability.
- Consistent Physical Properties: Standard relative density 1.75–1.77 g/cm³, melting point 160–170°C.
- Safe Packaging: Vacuum sealed in plastic bags to protect against moisture and contamination.
Applications:
- Lithium-ion battery cathode binder (mixing with NMC, LCO, LFP, etc.)
- Battery electrode slurry preparation
- Lithium battery research and development
- Small-scale electrode production
