DIY a Hydrogel electrolyte and electrode

DIY a Hydrogel Electrolyte and Active Electrode for supercapacitor and batteries.

For making the Hydrogel you need a Sodium Polyacrylate. For making the gel electrolyte you need to mix a Sodium Polyacrylate and water solutiun electrolyte (NaOH, KOH, P3SO4,...). You need to wait for couple of minute and you have the gel electrolyte. For making the active material for supercapacitors or batteries you need to mix a Sodium polyacrylate, electrolyte and active material (activated carbon, MnO2, NiOOH, graphite, graphene,...)
