Polyvinylidene fluoride binder

Introduction: Polyvinylidene fluoride binder(PVDF) is currently the most commonly used oil binder in the lithium ion battery industry. It is a non-polar chain polymer binder. It is characterized by strong oxidation resistance, good thermal stability and easy dispersion. N-methylpyrrolidone (NMP) is required as a solvent. This solvent has a high volatilization temperature, has a certain environment...

The anode of lithium battery is composed of anode active materials, conductive agent, battery binder and dispersant. The conventional anode electrode system is a water mixing process (the solvent is deionized water), so the incoming material does not require drying. This process requires: Conductivity of deionized water ≤1us/cm. Workshop temperature ≤40℃, Humidity :≤25%RH. After confirmation of th...

Polyvinylidene fluoride, referred to as PVDF, PVDF lithium ion battery binder is made of resin by adding some additives with specific properties, by injection molding or extrusion and other processing processes and polymers, is a highly non-reactive thermoplastic fluoropolymer, is a semi-crystalline fluoropolymer. Because of its good mechanical strength, chemical stability, electrochemical stabili...
