Probing Ion Mobility Mechanisms in Solid Electrolytes using 17-O Solid-State NMR Spectroscopy

The use of liquid electrolytes in Li-ion batteries is a fundamental safety concern and, as a result, novel solid electrolyte materials are urgently needed for the development of all-solid-state batteries. At present, many of the ion mobility mechanisms within solid electrolytes are either unknown or poorly understood, meaning they cannot be effectively optimised. This project will involve the preparation and characterisation of novel solid electrolyte materials based on perovskite- and garnet-type structures. The project will use multinuclear solid-state NMR spectroscopy, in conjunction with diffraction and computational methods, to explore the molecular structure, functionality and ion mobility mechanisms of novel solid electrolyte materials. In particular, the project will focus on the use of ¹⁷O enrichment methods to indirectly probe ion transport mechanisms. During the course of the project, a number of external research facilities will be utilised, including the UK 850 MHz SSNMR Facility and the ISIS Neutron and Muon Source.

Applicants should have a first-class or upper second-class Master’s degree.
