QENS studies of conductivity/hydride diffusion in barium hydride

Abstract: BaH2 has application in hydrogen storage technologies. We propose to study BaH2 by Quasi-elastic neutron scattering. We will perform scans at different temperatures for up twelve hours. The peak broadening will then be associated with local ion movements allowing us to extract diffusion coefficients and theoretical conductivity values. We plan to use an in-situ cell to measure conductivity. We can compare the two conductivity values and investigate any discrepancies. In our experiment, the change in neutron energies after diffraction will allow us to determine how hydride (H-) ions move inside the BaH2 solid. Understanding the movement of ions in solid materials is very important in the development of new technologies allowing for the storage and use of hydrogen as an energy source.
