Not simply small particles : Pair distribution function analysis (see picture) yields comprehensive insights into the electrochemical reaction of α‐Fe 2 O 3 with lithium. The metallic Fe formed in this reaction was found to be defect‐rich nanoparticles that restructure continuously without growing—an unusual characteristic likely linked to its highly reversible capacity.
