The development of resilient materials for use in batteries and fuel cells is a significant challenge. Understanding the fundamental mechanisms behind the degradation of candidate materials requires us to employ characterisation techniques which can reveal the atomic changes that are at work, and ideally in conditions approaching that used in relevant applications.
By exploiting the latest techniques in transmission electron microscopy, it is possible to reveal these phenomena. Working in close partnership with chemists and materials scientists in battery and catalyst development, it is possible to apply these insights into the realisation of more resilient materials.
Atomic Resolution Transmission Electron Microscopy
At Warwick we have access to one of the best TEM suites in the country, the EM RTP, including a double aberration corrected JEOL ARM200. Plus we are near to the UK's national EM centre, ePSIC, a state-of-the-art user facility TEM at Diamond Light Source.
To understand many materials processes it is insufficient to simply inspect the sample under vacuum of the TEM. In-situ experiments allow us to expand our experiment possibility space; capabilities such as in-situ electrical control and measurement, heating (to 1000 °C), liquid-nitrogen cooling, liquid, electro-chemical, and atmospheric control, all permit us to perform experiments within the TEM that reflect conditions beyond that of a simple room temperature vacuum.
In-situ Experiments for Advanced Characterisation
The Latest in Battery, Catalyst, and Nanomaterials
Warwick University hosts some of the world's leading scientists in the fields of battery development, catalyst engineering, and 2D material research. Much of our research involves close collaboration with these groups, and allows us to pursue ambitious experiments.
