Self-healable and stretchable ionogels serve as electrolytes and substrates for integrated all-in-one micro-supercapacitors

A type of ionogel electrolytes on the basis of a dual-dynamic network was prepared, composed of metal-ligand (Li+-PEO) coordination and hydrogen bonding, and a facile and versatile strategy for the construction of integrated all-in-one micro-supercapacitors was proposed to deliver promising electrochemical performance.
