Effects of LiClO4 on the Characteristics and Ionic Conductivity of the Solid Polymer Electrolytes Composed of PEO, LiClO4 and PLiAA
Solid polymer electrolytes (SPEs) which were composed of poly (ethylene oxide) (PEO), poly (lithium acrylate) (PLiAA), and LiClO4 were prepared in order to investigate the influence of LiClO4 content on the ionic conductivity of the electrolyte. All of the membranes were investigated by XRD, DSC, and EIS, et.al. The dependence of SPEs conductivity on temperature was measured, and the maximum ionic conductivity is 5.88×10-6 S/cm at 293 K for membrane which is composed of PEO+PLiAA+15wt% LiClO4. The electrochemical stability window of the PEO+PLiAA+15wt% LiClO4 is 4.75 V verse Li.
