Products Description
P210 PVDF Binder
P210 PVDF binder is a high-viscosity grade polyvinylidene fluoride (PVDF) homopolymer. It contains polar functional groups within its molecular structure, which enhance the interaction between polymer molecules, active materials, and metal electrodes. This improves adhesion performance and corrosion resistance in the electrolyte environment, making it particularly suitable for lithium iron phosphate (LiFePO₄) and ternary material systems used in the electric vehicle industry.
The binder effectively reduces the required formulation amount, lowers the battery’s DC internal resistance, and improves both energy density and charge/discharge performance. Additionally, it significantly enhances capacity retention during cycling, thereby meeting the high-performance demands of the automotive sector.
