The composite electrolytes were synthesized using three distinctly sized Al<sub>2</sub>O<sub>3</sub> nanoparticles with specific surface areas of 111, 9.08 and 6.02 m<sup>2</sup>/g respectively, while the LAGP particles had a specific surface area of 7.25 m<sup>2</sup>/g. Each composite electrolyte was synthesized with EO:Li equal to 16:1, while the volume proportion of added ceramic was varied from 0 to 18% in relation to the PEO-based polymer matrix. In general, electrolyte films containing particles with high surface area and loaded at low volume fractions had greater conductivities. For example, composite electrolytes containing Al<sub>2</sub>O<sub>3</sub> (111 m<sup>2</sup>/g) at a proportion of 3.5 vol.% showed the highest ionic conductivity of 3.99×10<sup>-5</sup> Scm<sup>-1</sup> at 30<sup>o</sup>C. Electrolytes containing LAGP particles generally performed better than films containing comparable sized Al<sub>2</sub>O<sub>3</sub>, such as the electrolyte containing LAGP (7.25 m<sup>2</sup>/g) at a proportion of 3.5 vol.% which obtained the second highest ionic conductivity of 2.24×10<sup>-5</sup> Scm<sup>-1</sup> at 30<sup>o</sup>C. Both electrolytes showed ionic conductivities approximately two orders of magnitude higher than the PEO-based electrolyte with no ceramic filler. 2018-05-31 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1522756200308156 http://rave.ohiolink.edu/etdc/view?acc_num=case1522756200308156 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
