Description
xCell Lab Polyvinylidene Fluoride (PVDF) [High Purity Binder, ≥99.6%] – Battery-Grade PVDF Powder for Cathode and Anode Fabrication
High-performance electrode binder for advanced lithium-ion battery research
The Cell Lab Polyvinylidene Fluoride (PVDF) is a high-purity, battery-grade fluoropolymer binder designed for electrode material mixing and coating in lithium-ion battery R&D and pilot production. Offering ≥99.6% purity, excellent chemical stability, and complete solubility in N-Methyl-2-pyrrolidone (NMP), this binder delivers strong adhesion and superior slurry rheology for both cathode and anode applications.
Engineered for use in LiCoO₂, NMC, LFP, graphite, and Si-C systems, Cell Lab PVDF ensures uniform electrode coatings, enhanced mechanical integrity, and excellent cycle stability even under high-voltage or elevated-temperature conditions.
Key Features
High Purity Binder
≥ 99.6 % purity ensures consistent electrochemical performance with minimal impurity-induced side reactions.
Excellent NMP Solubility
Completely dissolves in NMP to form a clear transparent solution for smooth slurry mixing.
Strong Adhesion and Flexibility
Provides durable binding between active materials and current collectors for long-cycle stability.
Superior Thermal and Chemical Stability
Resists common electrolyte solvents and maintains performance up to 160–168 °C.
Optimised Viscosity Control
High rheological consistency (≥ 2000 mPa·s) for uniform film formation and repeatable coating quality.

FAQ
Q1: Is this PVDF binder suitable for water-based systems?
No. This grade is NMP-soluble and intended for organic solvent systems. For aqueous binders, consider Cell Lab LA133.
Q2: What is the recommended binder content in electrode slurries?
Typically 2 – 5 % for anodes and 1.5 – 4 % for cathodes, depending on active material type.
Q3: Can this material be used for solid-state batteries?
Yes. It is often used as a matrix polymer or binder in solid-electrolyte interfaces.
Q4: How should PVDF be stored?
Keep sealed in a dry, cool place below 38 °C to prevent moisture absorption and viscosity change.
Q5: Does it require pre-baking before slurry mixing?
Pre-baking is optional but recommended (80 – 100 °C, 2 h) to ensure complete moisture removal.
