A polymeric solid electrolyte having a low glass transition temperature, obtained by complexing LuCIO 4 with an acrylic elastomer (AR) containing ester groups in the side chains, shows a conductivity of 2,0 · 10 −4 S/cm (LiCIO 4 : 2,1 mmol/g AR, film thickness: ca. 100–300 μm) at 80°C. From the relationship between ionic conductivity and LiCIO 4 concentration, we conclude that LiCI 4 dissociates in the acrylic elastomer to produce carrier ions. We also suggest, in regard to temperature characteristics of ionic conductivity and reciprocal dielectric relaxation time, that the driff of ions is related to the motion of acrylic elastomer chains. The carrier mobility in the acrylic elastomer‐LiCIO 4 complex was measured by using the voltage polarity reversing method. The carrier mobility increased with increasing LiCIO 4 concentration and temperature.
