Abstract

Gel electrolytes have been prepared by thermal polymerization of poly(polyethylene glycol dimethacrylate) (P(PEGD)) in the presence of propylene carbonate (PC) and alkali metal salts, such as LiClO₄, LiCF₃SO₃ and LiBF₄. The conductivity was studied by means of impedance spectroscopy, and it is found that the temperature dependence of conductivities follow a Arrhenius relationship when the molar percentage of PC is higher than 75% or LiClO₄ concentration is lower than 0.9mol/l. However, when LiCF₃SO₃ or LiBF₄ is used instead of LiClO₄ as the salt, the situation is different. For LiCF₃SO₃, the Arrhenius relationship almost holds true for all the salt concentrations studied; while for LiBF₄, the Arrhenius equation hardly fits for any salt concentration. The dependence of activation energy on salt concentration is also examined, both for LiClO₄ and LiCF₃SO₃, the values of E_a tend to reach a minimum value with increasing salt concentration.
