In this work, an efficient and simple solution blow spinning method for preparing well-aligned nanofibers was proposed. Compared with common electrospinning, this method is more promising for scalable fabrication because of fewer process requirements. Through this method, well aligned BaTiO3 nanofibers were fabricated, and their average diameter was about 300 nm. When introducing PEO and LiTFSI ionic conductive polymer composites into the aligned BaTiO3 nanofibers membrane, a composite solid-state polymer electrolyte was obtained. The excellent structure for the electrolyte was also analyzed and its electrochemical performance was tested. Results showed that the lithium ionic conductivity at 30 °C increased from 5.74 × 10–6 S · cm–1 to 5.83 × 10–5 S · cm –1 with addition of aligned BaTiO3 nanofibers, and its thermal and electrochemical stability were all significantly improved.
