From batteries for electric vehicles to electrolysers for green hydrogen production, the need for electrochemical technologies is clear. These technologies rely on a range of critical minerals, making high performance and long device lifetimes essential in ensuring sufficient materials supply in the decades to come.

This talk will discuss the use of advanced imaging methods to ‘see inside’ electrochemical devices as they are operating and failing. Given the inherent relationship between device performance and materials morphology, by understanding why and how the materials inside these devices fail, we can begin to develop the tools needed for designing the more resilient electrochemical materials of the future.
