Not simply small particles: Pair distribution function analysis (see picture) yields comprehensive insights into the electrochemical reaction of α-Fe2O3 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.
