500g Styrene-Butadiene Rubber (SBR) Binder for Li-ion Battery Anode

  • $ 27500


Product Details:

Styrene-Butadiene Rubber (SBR) is widely used as binder for battery anode preparation. Compared with PVDF, it has higher flexibility, stronger binding force, and higher heat resistance.  It is soluble in environmental friendly solvents such as water and ethylacetate which reduces the use of toxic N-Methyl-2-Pyrrolidone (NMP). Moreover, when used with Carboxymethyl cellulose (CMC), it is a trending binder for silicon based electrode which improves the cycling performance. 

This product is a water based binder which is mainly used to prepare anode electrode for Lithium-ion batteries with strong adhesion and high ageing-retardant.
