Hybrid organic–inorganic fibers for solid-state batteries

Abstract

This study is dedicated to the acquisition and quantification of processing parameters essential for the fabrication of customizable organic–inorganic hybrid nano/microfibers through electrospinning. These fibers are generated from suspensions comprising active electrode materials utilized in the construction of all solid-state batteries. Owing to the catalytic properties exhibited by certain electroactive materials and the coagulation tendencies stemming from the presence of various particles, there exists a limited operational interval within which stable fibers can be produced while maintaining the suspension at a suitable viscosity. Our second goal was to ascertain the relationship between the quality of the resulting fibers and the spinnability of the suspension, particularly regarding its electrical conductivity. Solutions and suspensions were studied with help of 29Si NMR spectroscopy, EIS, and conductometry, fiber morphology with confocal and electron microscopy.Graphical abstract
