All-round supramolecular zwitterionic hydrogel electrolytes enabling environmentally adaptive dendrite-free aqueous zinc ion capacitors

Abstract

An all-round supramolecular zwitterionic hydrogel electrolyte with the advantages of in situ repair, H 2 O-poor interface, and boosting the desolvation of hydrated Zn 2+ is proposed to enable the fabrication of environment-adaptive dendrite-free zinc ion capacitors.
