a Structure of the copolymers, containing a soft ___domain (PTMG) and a hard ___domain (MDI-EDA) with different ratios. b Stress-strain curves of the copolymers. c Swelling test of the polymer membranes in a 1 M LiPF6 in EC/DEC electrolyte. d Cycling stability of the SiO electrodes with the copolymers. The mass loading of SiO electrodes is 3.7 mg cm−2, and the copolymer amount is 0.4 mg cm−2. e Stress-strain curves of the copolymer 1 before and after swelling. f Peel adhesion of SiO electrodes. The electrode was peeled-off from the Cu current collector using a 90-degree dragging force. g Ionic conductivity measurement of the elastic GPE and liquid electrolyte as a function of temperature.
