Table S2: Arrhenius fit parameters of the ionic conductivity data for different electrolyte compositions plotted in Figure 6.

Figure S3 .
Figure S3.FT-IR spectra of monomer, 80 wt% SBE and 90 wt% SBE used to evaluate degree of cure.All samples were prepared outside the glovebox.

Figure S4 .
Figure S4.Digital images of structural battery electrolyte (SBE) dogbone samples corresponding to compositions of a) 90 wt% electrolyte, b) 80 wt% electrolyte, c) 70 wt% electrolyte, d) 60 wt% electrolyte, e) 50 wt% electrolyte, and f) pure resin.A change in opacity is observed with decreasing electrolyte content.The width of each sample is 3 mm.Note: The blue color is due to the ink used to mark the samples.

Figure S11 :
Figure S11: Equivalent circuit models used to fit the EIS data.The circuits corresponding to (a) represent the SBEs without any distinct bulk resistance and (b) SBEs with distinct bulk resistance.Circuit (a) represents a resistor in series with a constant phase element in which the resistor Rs represents the equivalent series resistance of the electrolyte/SBE and spacer and the constant phase element CPE represents the non-ideal capacitive component of impedance of the spacer.Circuit (b) represents a resistor in series with a constant phase element and a parallel combination of a resistor and a constant phase element.The resistor Rs represents the resistance of the stainless-steel spacer, resistor Rb represents the resistance of the SBE, constant phase element CPEb represents non-ideal capacitance of the SBE, and CPE represents the non-ideal capacitive component of impedance of the spacer.Circuit (a) was used to fit the data for the 100 wt% electrolyte sample.

Figure S13: Variation in ionic conductivity with temperature at different electrolyte concentrations.The data corresponds to Figure 5.

Figure S14 :
Figure S14: Differential scanning calorimetry (DSC) second heating curves of a) uncured resin, cured resin, and SBE compositions of varying compositions, and b) 90 wt% electrolyte SBE with minimal environmental exposure.

Figure S18 :
Figure S18: Specific modulus, a) as a function of electrolyte concentration at different temperatures, b) as a function of temperature for 80% electrolyte concentration, c) as a function of temperature for 90% electrolyte concentration.The red strip in (a) represents the pure resin modulus at room temperature (where the center line is the mean value and the shaded region is the associated error).Note: The specific modulus predicted by the rule of mixtures is (by definition) the same as the specific modulus of 100 wt% resin.
