Network polymer electrolytes based on poly(ester diacrylate), LiClO sub(4), and ethylene carbonate are synthesized and investigated via the methods of electrochemical impedance spectroscopy, DSC, and thermal analysis. It is found that, for the polymer-LiClO sub(4) system, the conductivity is 4.2 10 super(-7) S/cm at 20 degree C. With a gradual increase in the amount of ethylene carbonate, the conductivity first decreases and then increases. It is shown that, when poly(ester diacrylate) is crosslinked in ethylene carbonate, up to 45.5% of the latter compound is retained in the polymer and not lost during heating to 100 degree C. The conductivity of the electrolyte containing 45.6 wt % poly(ester diacrylate), 45.5 wt % ethylene carbonate, 7.5 wt % LiClO sub(4), and 1.4 wt % benzoyl peroxide achieves 1.9 10 super(-4) S/cm at 20 degree C.
