Poly(acrylic acid) binder (PAA) - 25 mL
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(acrylic acid) binder (PAA) is a water-soluble polyacrylate with high number of functional groups. Particularly, carboxyl groups can form strong hydrogen bonds with both active material and current collector. Other quantities are available on request.
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. It is strongly recommended to degas the slurry before coating. The resulting slurry is coated on current collector (e.g. doctor blade) and dried (usually at 80°C) in vacuum or ambient environment.
