Quasielastic neutron scattering (QENS) is a powerful technique for probing atomic and molecular motion on nanosecond to picosecond timescales. In many energy materials, for example batteries and fuel cells, understanding ionic migration and conduction pathways is crucial for optimising performance. QENS can provide a unique insight into both local and long-range diffusion, with length- and time-scales comparable to molecular dynamics simulations. This complementarity helps interpret experimental data and validate computational models. This talk will introduce QENS and present a case study demonstrating how combining QENS with simulations can reveal key details of oxide ion diffusion in a solid electrolyte.
