We applied a slide-ring (SR) gel to a Mg2+ion gel electrolyte and clarified the electrical and mechanical properties in order to achieve a Mg2+ion gel electrolyte with both sufficient mechanical strength and high ionic conductivity. The SR gel is made from polyrotaxane, which has a structure that consists of cyclic molecules, α-cyclodextrins (CDs), threaded by an axial polymer chain, polyethylene glycol (PEG), and cross-linked by divinyl sulfone. Pure glymes and tetraethylene glycol dimethyl ether (tetraglyme: G4) dissolving Mg2+ions had no ability to swell the SR gel, whereas diethylene glycol dimethyl ether (diglyme: G2) and triethylene glycol dimethyl ether (triglyme: G3) dissolving Mg2+ions were able to swell the SR gel. The swelling behavior was strongly dependent on the interaction between Mg2+ions complexed with glymes and ether oxygens of a PEG-based hydroxypropyl PR (HyPR) network. Upon tensile elongation, SR gel swollen with G3 solution dissolving Mg2+ions could be extended by 300%, which indicated the unique property of high ductility. The ionic conductivity of SR gel swollen with G3 dissolving Mg2+ions, which approximately satisfied a Vogel-Tamman-Fulcher (VTF) dependence, was 1.73 mS cm−1at room temperature, and the molar conductivity was 67% of that for a pristine G3 solution dissolving Mg2+ions.
