💡 Novelty & Significance:
This work pioneers 6Li solid-state NMR to directly visualize lithium environments in paramagnetic LiFeCl3 cathodes, revealing hidden Li/Fe disorder, reversible intercalation-conversion chemistry, and trace Fe0 degradation. This enables optimized voltage windows achieving 85.9% retention over 500 cycles, establishing lithium-resolved NMR as a powerful platform linking disorder, hidden redox, and reversibility in all-solid-state batteries.
