Abstract

A polyethylene oxide (PEO)-based composite solid polymer electrolyte filled with one-dimensional (1D) ceramic Li_0.33La_0.557TiO₃ (LLTO) nanofibers was designed and prepared. It exhibits a high ionic conductivity of 2.4 × 10⁻⁴ S cm⁻¹ at room temperature and a large electrochemical stability window of up to 5.0 V vs. Li/Li⁺, and is a promising electrolyte candidate for all solid-state lithium batteries.
