Binders used in functional coatings (e.g. electrodes) act as‘glue’, which secures the active material to current connector and keeps its structural integrity. The choice of suitable binder is not straight forward, and many researchers struggle to find the most suitable polymer for their application. This binder kit consists of 7 common compositions used in coatings for various applications (25 mL each), particularly in electrochemistry and energy storage/conversion (thin-film electrodes, batteries and supercapacitors, photovoltaic cells). The wide selection of polymers allows to test and compare several binders without the need of purchasing large quantities of singular products. Depending on composition, the binder kit can be used for both aqueous and organic environments to make free-standing film/membrane or thin/thick film coating on current collector. Other quantities are available on request.

Application note
The binders are provided as liquid solutions/dispersions/emulsions with specific concentration. The appropriate 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 appropriate solvent 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.
