Lithium - ion battery anode water - based binder SBR 53%, Styrene - Butadiene Rubber with 49% total solid content and 142mPa·s Brookfield viscosity. Its small - molecule linear structure improves electrode adhesion. 1kg bottles meet the bonding needs of graphite anodes and copper foil, supporting high - stability battery manufacturing.
Styrene-Butadiene Rubber (SBR 53%) is a water-based binder for lithium-ion battery anodes. With a total solid content of 49% (48-53% standard), pH of 5.3 and Brookfield viscosity of 142mPa·s, it offers great dispersion and adhesion. Its small-molecule linear structure quickly dissolves in polar solvents to form a uniform milky solution with a bluish luster. It effectively bonds graphite, conductive agents and copper foil, boosting electrode flexibility and cycle life. Low ionic residue cuts electrolyte side reactions, making it suitable for high-energy-density batteries. Packaged in 1kg bottles, it meets lab-to-pilot-scale needs and is widely used in manufacturing lithium-ion battery anodes for power batteries and 3C digital devices, enhancing fast-charging and low-temperature performance.

FAQ
Q1: Does Styrene Butadiene Rubber(SBR) need to be diluted before use?
A: With a total solid content of 49%, the product can be used directly. If viscosity adjustment is needed, dilute with deionized water and use high - speed stirring to ensure uniform dispersion.
Q2: Is Styrene Butadiene Rubber(SBR) suitable for high - temperature electrode baking processes?
A: The latex can withstand temperatures up to 150℃, so it's compatible with the conventional electrode baking process at 80 - 120℃. After film formation, there's no cracking or falling off.
Q3: Can Styrene Butadiene Rubber(SBR) be used with the NMP solvent system?
A: As a water - based product, it requires stepwise processing with organic solvents like NMP. It's recommended to complete the coating and drying of the aqueous slurry first, and then carry out subsequent processes.
Q4: How to store Styrene Butadiene Rubber(SBR) after opening?
A: Store it sealed in a cool place at 5 - 30℃, avoiding freezing or sun exposure. It's advised to use it up within 3 months after opening to prevent serum separation of the emulsion.
Q5: Does Styrene Butadiene Rubber(SBR) contain volatile organic compounds (VOCs)?
A: The formulation is a water - based and environmentally friendly system. It doesn't contain VOC components like toluene or acetone, and it meets the safety standards for lithium - battery production environments.
