Categories PVDF for Lithium Batteries Album View larger image Brand Flurine Model FL2800 Features Copolymer, low to medium viscosity Uses Battery binder,lithium iron phosphate Forms White powder Update Time 2021-03-02 Detail InformationZheflon® FL2800 is a medium to low viscosity grade polyvinylidene fluoride copolymer. It imparts a certain flexibility to the material while reducing the crystallinity of the polymer. It can enhance the interaction between polymer molecules, active materials and metal pole pieces, improve adhesion performance and improve the solid content of slurry. It is especially suitable for the application of lithium iron phosphate system in electric vehicle industry.
Zheflon® FL2800 can effectively reduce the amount of formula used, reduce the DC internal resistance of the battery, improve the energy density and charge and discharge performance of the battery, and effectively increase the capacity retention rate of the battery during the cycle to meet the needs of the automotive industry.

1.PVDF should be processed under 260℃,to avoid producing toxic gases;2.PVDF has good fire resistance and smoke inhibition property, however, when meets with fire, it will release toxic hydrogen fluoride gas and fluorocarbon compounds;3.Operators should take good care of personal protection during the use procedure and processing.PVDF is packed in PE plastic bag and then be put into a drum with the net weight 25KGS. It must be stored in clean, cool, dry place.
