At this point, the polymer absorbed oxygen and generated insulating materials, which isolated the defective portion from the remainder of the capacitor. Despite the loss of some effective capacitance, the self-healing process had a negligible impact on the overall performance, while substantially reducing the LC [40, 41].
Based on these excellent properties, an all-in-one self-healing supercapacitor is assembled by in situ polymerization of aniline on the surface of PVA/H 2 SO 4 hydrogel electrolyte.
A self-healable and highly stretchable supercapacitor based on a dual crosslinked polyelectrolyte Stretchable and self-healing integrated all-gel-state supercapacitors enabled by a notch-insensitive supramolecular hydrogel electrolyte ACS Appl. Mater.
Meanwhile, a flexible solid-state capacitor was assembled based on PANI–PVA hydrogel as electrode and PA–PVA hydrogel as electrolyte. Traditional all-solid-state supercapacitors consist of an electrode, an electrolyte, and a separator.
Based on PANI–PVA composite hydrogel, a flexible all-solid-state supercapacitor was fabricated to further investigate the electrochemical performance and self-healing properties.
