Product Overview

Matlabs Technologies’ SBR Binder (SBR2919) is a high-quality water dispersible polymer binder designed for anode electrode fabrication in lithium-ion batteries. Unlike solvent-based binders such as PVDF, SBR is water-soluble and environmentally friendly, eliminating toxic organic solvents during slurry preparation and coating.

This binder provides exceptional flexibility and adhesion between active materials, conductive additives, and current collectors (e.g., copper foil). It also exhibits good mechanical durability and ageing resistance — particularly when used in combination with Carboxymethyl Cellulose (CMC) — making it ideal for silicon-enhanced anodes and advanced graphite formulations.

Features & Benefits

Water-Based Eco-Friendly Binder – Reduces reliance on hazardous solvents (NMP) and supports safer processing.
Strong Adhesion & Elasticity – Enhances electrode integrity and accommodates volume changes during cycling.
High Ageing Resistance – Improves cycling stability and lifetime.
Ready for Anode Slurry Production – Works effectively with conductive carbon and CMC binder systems.
Easy to Handle & Disperse – Milky liquid form ensures uniform dispersion in aqueous slurries.

Typical Applications
  • Lithium-Ion Battery Anode Slurries – Water-based binder for high-performance anode formulations.
  • Silicon/Graphite Composite Electrodes – Ideal in combination with CMC for improved cycle life.
  • Battery R&D & Prototyping – Suitable for research labs and pilot cells.
  • Eco-Friendly Manufacturing – Supports water-based electrode coating lines.
Usage & Handling

SBR binder is typically added to de-ionized water and mixed thoroughly with active anode powders and conductive carbon to form a uniform slurry. For improved mechanical performance, SBR is commonly paired with Carboxymethyl Cellulose (CMC) to balance viscosity and adhesion during coating and drying.

Storage: Keep in a sealed container at 0–38 °C. Avoid freezing and direct sunlight to preserve binder properties.
