PhD Studentship: Powering the Future: Terahertz Technology for Next-Generation Batteries

From electric vehicles to grid-scale energy storage, the future of clean energy relies on breakthroughs in battery technology. This PhD will develop cutting-edge terahertz spectroscopy methods to unlock scalable manufacturing of next-generation solid-state batteries.

The project:

Solid-state electrolytes are attracting growing interest for next-generation solid-state batteries due to their improved thermal stability, reduced flammability, enhanced durability, and potential for higher energy density. However, manufacturing high-performance electrolytes remains challenging, as their microstructures must be carefully controlled and optimised to ensure good electrochemical performance, mechanical integrity, and impermeability. This challenge is compounded by the lack of rapid inspection methods capable of assessing microstructural homogeneity, which is increasingly important for product-scale electrolytes.

The PhD candidate will join a dynamic, interdisciplinary research team working at the interface of metrology, battery materials, and ceramic processing. Building on our previous demonstrations [1], this project will begin with the fabrication and characterisation of conventional electrolyte materials using emerging terahertz spectroscopy. The work will then progress to developing the technique further for measurements on product-scale electrolytes. In the later stages of the project, thermal control will be integrated to probe intrinsic conduction behaviour and link this to longer length-scale conductions, establishing a unified framework connecting microstructure and transport mechanisms.

In close collaboration with LiNa Energy, this project offers an exciting opportunity to contribute directly to innovations in solid-state battery manufacturing, advanced metrology, and quality control for next-generation energy storage devices.
