✦ Synopsis
AImtract-Novel single and double ion type solid electrolytes which have poly(dimethylsiloxane) backbones and crosslinked networks, are prepared and characterized with ir, X-ray diffraction, DSC, conductivity, and transference number measurements. We can prepare both type electrolytes by using the same prepolymers. At room temperature, conductivity and transference number of lithium ion are about lo-'Scm-' and 0.50456 in double ion type, and about 10m6 S cm-' and 0.98 in single ion type. Temperature dependences of conductivity were different for each type of electrolyte. Double ion type shows WLF dependence In single ion type electrolyte, discontinuous increase in conductivity is observed at about 2O"C, which is induced by a phase transition.
