Deep Inelastic Neutron Scattering study of La2LiHO3 and La2LiDO3 oxyhydrides

Abstract: Oxyhydrides represent a new class of materials which is as yet poorly understood. The recent exciting discovery of the first purely hydride conducting oxyhydride is promising for the future of solid-state electrochemical devices, as the high redox potential of Hydride ions (-2.3 V (H-/H2)) makes them very relevant for high energy density applications. Despite proving the existence of hydride conduction within these materials, there is currently no understanding of the microscopic mechanisms for the diffusion, which is crucial for developing future devices. In this experiment we aim to measure the dissociation energy of the hydride anions in the La2LiHO3 oxyhydride. By doing so, we will gain fundamental insight to the underlying physics of oxyhydrides, which is essential to improve the functional properties of oxyhydrides if they where to be employed in future technology.
