Regenerated hydrogel electrolyte towards an all-gel supercapacitor [PDF]

Science China Materials, 2021
Electrolyte regeneration is an important goal for environmental protection and sustainable development efforts. Herein, we report a facile strategy inspired by the transformation of edible dough from flour to regenerate hydrogel electrolytes from their dehydrated copolymer granules (CGs) via direct addition of water or salt solution.
