Battery Grade PVDF Powder Binder for Lab Raw Materials
PVDF Powder Binder for Li-ion Battery Cathode Raw Material
Chinese Name: kynar
Application: Binder for lithium ion battery positive electrode active material, generally mixed with NMP solvent
Appearance: White powder
English Name: Polyvinylidene Fluoride/ PVDF
High purity >99.5%
Good chemical stability
Usage:
l761A is a kind of powder - like polyvinyl fluoride product, which has good solubility in some solvents.
lCompared with other brands of 761A, PVDF is more suitable as a lithium battery electrode binder material, less than similar products, thereby increasing the capacity of the battery.
l761A is a kind of polymer material with high dielectric constant, which has high viscosity and adhesion in a certain solvent.
lThe lithium battery membrane electrode material made of 761A has good chemical stability, temperature stability and good workability.
