what the original flaw was or where it occurred. But using the MRI technique we’ve developed, we can actually see what’s going on inside the battery while it is operational, giving us unprecedented insights into how the sodium behaves.”

"This technique provides gives us information into the change within the battery components during operation of a sodium ion battery, which are currently not available to us through other techniques," she added. "This will enable us to identify methods for detecting failure mechanisms as they happen, giving us insights into how to manufacture longer life and higher performing batteries."

The techniques used by the team were first designed in a collaboration with researchers at the Sir Peter Mansfield Imaging Centre at University of Nottingham which was funded by the Birmingham-Nottingham Strategic Collaboration Fund. This project, with access to MRI technologies from Phlips and GE, is developing MRI scanning of sodium isotopes as a medical imaging technique and the team were able to adapt these protocols for use in battery imaging.
