The decisive chemistry of iron-based halide cathodes─where lithium resides, how it evolves, and how disorder governs multielectron redox─has remained largely inaccessible, limiting the rational design of catholyte-free composite cathodes in all-solid-state lithium batteries. Here we make the lithium sublattice directly visible in paramagnetic LiFeCl3 using a 6Li solid-state NMR strategy combining high isotopic enrichment, optimized acquisition, and variable-temperature control. This method...
