Cell Lab LA133 Aqueous Binder [Water-Based, High Viscosity, Eco-Safe] – Advanced Acrylonitrile Copolymer Binder for Lithium-Ion Battery Electrodes

High-viscosity, water-based polymer binder for anode and cathode slurry formulation

The Cell Lab LA133 Aqueous Binder is a high-performance, water-based acrylonitrile copolymer binder designed for use in both anode and cathode materials. Offering excellent anti-oxidation and anti-reduction properties, it is ideal for a broad range of electrode chemistries including LiCoO₂, LiMn₂O₄, LiFePO₄, and carbon-based systems.

Its eco-friendly water dispersion eliminates the need for organic solvents, reducing processing hazards while maintaining high binding strength and film uniformity. The binder’s adjustable viscosity, strong adhesion, and consistent electrochemical performance make it a preferred choice for research laboratories and battery manufacturers focusing on sustainability and efficiency.

Key Features

Broad Material Compatibility
Effective for both cathode and anode materials, including emerging systems like lithium–sulphur and silicon–carbon composites.

High Viscosity Without Thickener
Maintains superior binding and dispersion without requiring additional viscosity modifiers.

Enhanced Electrochemical Stability
Improves cycle life, reduces cell polarisation, and enhances electrode rate capability.

Water-Based and Environmentally Safe
Non-toxic, solvent-free aqueous formula reduces production risk and environmental impact.

Adjustable Processing Properties
Viscosity can be tuned via water content; binder remains stable under storage and thickens gradually for process control.

Technical Specifications

Application Guidelines

Binder Content Recommendations:

• Anode: 2–5 %

• Cathode: 1.5–4 % (higher for LiFePO₄ formulations)

Slurry Preparation:
Adjust viscosity using deionised water; employ vacuum defoaming or small quantities of ethanol/n-butanol to remove air bubbles.

Electrode Processing:
Ensure thorough drying; allow electrodes to cool before rolling, cutting, or winding.

Battery Assembly:
Completely remove moisture before electrolyte injection to maximise performance.

Storage Notice:
Viscosity increases gradually over time; store in a cool, sealed container below 38 °C.

Applications & Industries

• Lithium-ion and sodium-ion battery electrode fabrication

• Cathode/anode slurry preparation and coating research

• Eco-safe battery material formulation

• Academic and industrial battery manufacturing

• Sustainable polymer binder development

FAQ

Q1: What advantages does LA133 have over PVDF binders?
LA133 is water-based and solvent-free, reducing cost and environmental risk while maintaining strong adhesion and electrochemical performance.

Q2: Is it suitable for high-loading electrode formulations?
Yes. The binder provides strong cohesive strength even in dense electrode coatings, improving flexibility and cycle life.

Q3: Can LA133 be used with aqueous conductive additives?
Yes. It is compatible with carbon black, graphene, and CNT dispersions in water-based systems.

Q4: How can viscosity be adjusted for different coating methods?
Add small amounts of deionised water for slot-die or doctor-blade coating, ensuring uniform film thickness.

Q5: What is the shelf life of the product?
Under recommended storage (< 38 °C), the binder remains stable for 12 months without significant viscosity drift.
