Well-aligned batio₃ nanofibers via solution blow spinning and their application in lithium composite solid-state electrolyte

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.Though this method �well aligned BaTiO₃ nanofibers were fabricated, and their average diameter was about 300 nm. When introducing PEO and LiTFSI ionic conductive polymer Delivered by Ingenta 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.
