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 SPE is deficient at room temperature. Thus, to study suitable 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 in SPE and the change of ionic conductivity according to the architecture and the number of carbon atoms in repeating unit was studied systematically. And physical and electrochemical property of PAC based SPE were estimated by means of FT-IR, 1H NMR, impedance analyzer, differential scanning calorimetry (DSC) and optical tensiometer. |
