Description
PVDF Binder for Li-ion Battery Electrodes – ≥99.5% Purity
Our Polyvinylidene Fluoride (PVDF) Binder is a high-purity white powder specifically designed for lithium-ion battery electrodes. With a purity of ≥99.5% and excellent binding properties, it ensures optimal adhesion of the active material to the current collector, contributing to long-term battery stability and enhanced performance.
PVDF exhibits outstanding electrochemical and thermal stability, high dielectric constant, and good solubility in common solvents like NMP (N-Methyl-2-pyrrolidone). These characteristics make it ideal for both cathode and anode slurry formulations in Li-ion battery manufacturing.
Beyond energy storage, PVDF also finds use in plumbing systems, water filtration membranes, architectural coatings, and renewable energy components due to its chemical resistance and mechanical durability.
