Description
Battery Anode SBR Binder – Water-Based Styrene Butadiene Rubber for Li-Ion Anodes
SBR (Styrene Butadiene Rubber) is a water-based binder specifically designed for the preparation of anode electrodes in lithium-ion batteries. As an aqueous emulsion, it offers an environmentally friendly alternative to solvent-based binders while providing excellent adhesion and mechanical flexibility.
Key Characteristics:
- Water-Based System: Environmentally friendly, reduces VOC emissions, and simplifies electrode manufacturing process.
- Strong Adhesion: Ensures excellent bonding between active materials (graphite, silicon), conductive additives, and the copper current collector.
- High Aging-Retardant: Maintains binding properties over extended periods, contributing to battery cycle life.
- Good Flexibility: Accommodates volume changes in anode materials during charge/discharge cycles.
- Consistent Quality: Manufactured under strict quality control with stable physical and chemical properties.
Typical Applications:
- Lithium-ion battery graphite anodes
- Silicon-containing anode formulations
- Composite anode materials
- Water-based electrode slurry systems
- Laboratory R&D of anode formulations
