Currently, the solid polymer electrolyte (SPE) that can be able to use the lithium metal anode has got a lot of interest, because of the demand for development of electric cars and energy storage device. However, it is difficult in the commercialization because the ionic conductivity of the SPE is deficient at room temperature. Thus, to study about the appropriate polymer for SPE, poly(alkylene carbonate)s(PACs) which can be dissolved the salt due to the fact that high density of coordination site were introduced as the SPE and the change of ionic conductivity according to the construction and the number of carbon atoms in repeating unit was studied systematically. And physical and electrochemical property of PACs based SPEs were estimated by means of FT-IR, 1H NMR, impedance analyzer, differential scanning calorimetry(DSC) and optical tensiometer. |
