Not simply small particles: pair distribution function analysis 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.
配分函数分析为 α-Fe(2)O(3)与锂的电化学反应提供了全面的见解。研究发现,该反应中形成的金属 Fe 是富含缺陷的纳米颗粒,它们在不生长的情况下不断重构——这种不寻常的特性可能与其高可逆容量有关。
