Summary: A new type of macromolecule chemical cross-linked network ionic gel polymer electrolyte (MCIGPE) was designed based on chitosan and dibenzaldehyde-terminated poly(ethylene glycol) (PEGDA) via dynamic imine bonds. The MCIGPE-65 showed an ionic conductivity of 2.75 x 10(-2) S cm(-1). A symmetric all-solid-state supercapacitor using MCIGPE-65 as the gel polymer electrolyte exhibited a high specific capacitance of 51.1 F g(-1) at 1 A g(-1) and an energy density of 7.1 Wh kg(-1) at a power density of 500.2 W kg(-1).
