Abstract
A new multifunctional polyelectrolyte, particularly suitable for a solid-state supercapacitor, is obtainable or obtained by reacting an effective amount of vinyl hybrid silica nanoparticles (VSNPs) and a compound having a structural unit based on acrylic acid or a structural unit derived therefrom in the presence of a polymerization initiator. The polyelectrolyte allows for an advantageous tunable ionic conductivity, exceptional self-healability and super-stretchability. An energy storage device, in particular a solid-state supercapacitor, includes the polyelectrolyte. A method for manufacturing a solid-state supercapacitor as well as for repairing a solid-state supercapacitor having cracks is also disclosed. Benefiting from the superior properties of the polyelectrolyte, the energy storage devices based thereon exhibit highly advantageous stretchability and self-healability and an exceptional performance compared to conventionally known devices.
