  The new methodology proposed in this work uses oxide filaments/fibers instead
of a dense thin film electrolyte, allowing: (i) straightforward fabrication
without the use of costly thin film production techniques, (ii) minor changes
in the existing Li- ion battery production lines, and (iii) better mechanical
stability and electrochemical performance. Li7La3Zr2O12 (LLZO) fibers as an
electrolyte were prepared using the electrospinning technique. The
crystallographic phase and morphology of the products was studied X-ray
diffraction (XRD) patterns and scanning electron microscopy (SEM),
respectively. The results indicated that the produced electrolyte would be a
good alternative of all-solid-state batteries for electric vehicles in terms of
battery safety and performance.
