Product Description
Li-ion Battery Anode Slurry Mixing Machinery Styrene-Butadiene Rubber Binder
Styrene-butadiene rubber (SBR)
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite). These materials have good abrasion resistance and good aging stability when protected by additives. SBR is derived from two monomers, styrene and butadiene. The mixture of these two monomers is polymerized by two processes: from solution (S-SBR) or as an emulsion (E-SBR).E-SBR is more widely used.SBR is also used as a binder in lithium-ion battery electrodes, in combination with carboxymethyl cellulose as a water-based alternative for, e.g. polyvinylidene fluoride.
An electrode binder for lithium-ion (Li-Ion) secondary batteries is used either to bind active material layers or between active material layers and collectors. The binder in general is preferably electrochemically inert. Although the binder is not essential for the battery, it has an important role in the facilitation of producing batteries and in their properties.
