Exploring a self-healing hydrogel electrolyte: Fabrication andsupercapacitors applications

Flexible and lightweight energy storage systems with superior performance have received greatattention recently due to the development of portable and flexible electronic devices. Supercapacitorsthat are flexible are among the most interesting energy storage systems. Hydrogel electrolytes emergeas a critical component of these systems. Meanwhile, flexible self-healing hydrogels play a crucialrole in the design of flexible supercapacitors. Using hydroxy-acrylate and vinyl-imidazolium as thestarting components, herein we report the preparation of a hydrogel electrolyte bearing reodxreactions and self-healing properties. A specific capacitance of almost ۱۱۵.۵ Fg-۱ was reported at ascan rate of ۵ mV s-۱, when the hydrogel employed as both electrolyte and separator in a symmetricsupercapacitor.
