PVDF Binder Water-Based (Aqueous Cathode Grade)
CAS Number: 24937-79-9
Water-based PVDF binder (PVDF latex/dispersion) eliminates NMP solvent and associated recovery systems, enabling greener cathode manufacturing with reduced capital cost and carbon footprint. Designed for LFP and NMC cathode aqueous slurry processes, it provides adhesion and electrochemical performance comparable to NMP-based PVDF.
Technical Specifications

Applications
- Waterborne LFP cathode slurry binder
- NMC cathode aqueous processing
- Green dry-room-free electrode manufacturing
- Semi-dry electrode process binder
- Separator aqueous coating binder
Key Features
- Eliminates NMP solvent, reducing VOC emissions and removing need for solvent recovery
- Comparable adhesion and cycle performance to NMP-based PVDF in LFP cells
- Low-temperature drying (80–120°C) reduces energy consumption versus NMP process
- Compatible with carbon black and graphite conductive agents in aqueous slurries
