Polyvinylidene fluoride, the standard binder for lithium-ion cathode electrodes. Dissolved in NMP, it forms a network that adheres the active material and conductive additive to the current collector. Its chemical resistance to electrolyte and stability across a wide voltage window leave it almost without alternative on the cathode side.
Key Features

- Balanced slurry rheology from a solution viscosity of 0.27-0.31 l/g
- Melting point of 160.0-168.0°C, stable at electrode drying temperatures
