Poly(ethylene oxide)-LiTf-Al2O3 and Poly(ethylene oxide)-LiTf-Li1.5 Al0.5Ge1.5(PO4)3 composite solid electrolyte films for use in Lithium ion batteries were fabricated by aerosol jet deposition. The composite electrolytes were synthesized using three distinctly sized Al2O3 nanoparticles with specific surface areas of 111, 9.08 and 6.02 m2/g respectively, while the LAGP particles had a specific surface area of 7.25 m2/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 Al2O3 (111 m2/g) at a proportion of 3.5 vol.% showed the highest ionic conductivity of 3.99×10-5 Scm-1 at 30oC. Electrolytes containing LAGP particles generally performed better than films containing comparable sized Al2O3, such as the electrolyte containing LAGP (7.25 m2/g) at a proportion of 3.5 vol.% which obtained the second highest ionic conductivity of 2.24×10-5 Scm-1 at 30oC. Both electrolytes showed ionic conductivities approximately two orders of magnitude higher than the PEO-based electrolyte with no ceramic filler.
