Presentation Title Neutron Scattering Visualizing Defects Generation and Structure Recovery in Ball-milled Spinel Oxide

On-Site Speaker (Planned) Yan Chen
Abstract Scope In complex oxides, the crystal defects such as atom disordering, vacancies and incoherent boundaries usually act as determinative factors of materials’ superior performance. The understanding and control of those defects in hierarchical structures are essential in the design of material synthesis and manufacturing. Neutron diffraction has unique capabilities to detect vacancies of light-weight elements and ordered arrangement of transition-metal-elements in lattice; the small-angle neutron scattering reveals the evolution of crystallites from nano to micro scale; the in-situ approach enables revealing the intermediate status and reversible process in synthesis. This presentation demonstrates those capabilities via an example of high-energy ball milling on LiNi0.5Mn1.5O4 spinel for energy storage use. The ball-milling effects on structure breakdown, defect generation and atom disordering are revealed. The structure recovery is visualized in the subsequent annealing. This study illustrates that neutron characterization is valuable to guide optimization of synthesis for advanced materials.
