Binders used in functional coatings (e.g. electrodes) act as ‘glue’, which secures the active material to current connector and keeps its structural integrity. Poly(vinylidene fluoride) binder (PVDF) is one of the most common binders, used for example in cathodes for Li-ion batteries, which can be used as benchmark for comparisons. It is dissolved in N-methyl-2-pyrrolidone (NMP). 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. Use NMP to dilute if necessary. The resulting slurry is coated on current collector (e.g. doctor blade) and dried (usually at 80°C) in vacuum or ambient environment.
