Low-Temperature lonic-Liquid-Based Synthesis of Nanostructured Iron-Based Fluoride Cathodes for Lithium Batteries

摘要

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 microstruc-tural 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 FeF_3 ? 0.33 H_2O at room temperature.
