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. Based on some preliminary muon measurements, we have proposed a set measurements to firstly determine the muon site within our material, and then probe the question of the precise mechanism for microscopic hydride diffusion.
