Zheflon® 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.
