Binders used in functional coatings (e.g. electrodes) act as ‘glue’, which secures the active material to current connector and keeps its structural integrity. Carboxymethyl cellulose binder (CMC) is a popular thickener used in number of industries, including commercial anodes for Li-ion batteries. It can be used as sole binder or as a thickener for SBR for adjusting the viscosity. Non-toxic solution in water is easily processable and can be further diluted with water if needed. Other quantities are available on request.

Application note The binder is thoroughly mixed with the active material, where ratio can range from 30:70 to 1:99, respectively, depending on application, active material, additives etc. If necessary, the mixture can be diluted with water to achieve required viscosity. The resulting slurry is coated on current collector (e.g. doctor blade) and dried (usually at 80°C) in vacuum or ambient environment.
