Zheflon® FL2100 PVDF- Lithium battery Binders Grade
CategoriesZheflon® FL2100 PVDF- Lithium battery Binders Grade
Categories PVDF for Lithium Batteries Brand Flurine Model FL2100 Features Copolymer, high viscosity Uses Li-battery binders,lithium iron phosphate,ternary Forms White powder Update Time 2021-08-02 Detail InformationZheflon® FL2100 is a high-viscosity grade of polyvinylidene fluoride copolymer containing polar functional groups in the molecule, which can enhance the interaction between polymer molecules, active materials and metal pole pieces, also improve the adhesion performance and corrosion resistance in the electrolyte, which is particularly suitable for the application of Lithium iron phosphate and ternary system in the electric vehicle industry.
Zheflon® FL2100 can effectively reduce the amount of formula, reduce the DC resistance of the battery, improve the energy density and charge-discharge performance of the battery, effectively increase the capacity retention rate of the battery during the cycle, and thus meet the needs of the automotive industry.
