Low‐Temperature Ionic‐Liquid‐Based Synthesis of Nanostructured Iron‐Based Fluoride Cathodes for Lithium Batteries

Abstract

A mesoporous iron-based fluoride cathode for lithium batteries is fabricated by a novel low-temperature non-aqueous synthesis based on ionic liquid medium. The hydration-water-induced microstructural optimization and morphological decoration are expected to contribute positively to both the large reversible Li-storage capacity and the high reactive voltage of carbon-free FeF3 · 0.33H2O at room temperature.
