A fibrous solid electrolyte for lithium-ion batteries

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.
