A novel and high-effective redox-mediated gel polymer electrolyte for supercapacitor

- Alkali and P-phenylenediamine doped polyvinyl alcohol gel electrolyte is prepared.
- The PVA-KOH-PPD gel electrolyte can also be used as separator.
- The introduction of PPD increases the ionic conductivity of electrolyte.
- The supercapacitor exhibits flexible and high energy density.
