Binders used in functional coatings (e.g. electrodes) act as ‘glue’, which secures the active material to current connector and keeps its structural integrity. Water dispersion of acrylonitrile multi-copolymer is used in battery industry. It is comparable to SBR binder, but benefits from better electrochemical stability and no need of additional thickeners. 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. Water is used to dilute the mixture 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.
