Vinyl acetate-ethylene as a potential alternative to fluorine free binders in supercapacitors

Supercapacitors are an environmentally friendly energy storage technology that is in increasing demand. However, the binder materials used in the electrodes of supercapacitors often contain fluorine components, which are ecologically harmful and are the subject of upcoming restrictions. This study presents an ecologically friendly alternative: vinyl acetate/ethylene (VAE) modified carbon materials in aqueous supercapacitors. It describes initial measurements obtained in VAE-based supercapacitors filled with KOH or Na2SO4. The materials and methods used can, however, also be applied to other aqueous capacitors and batteries.
