Abstract

Solid-state batteries hold a lot of promise for future technological innovations. They have the potential to be more energy-dense, safer, and be used in a wider range of temperatures. With these attributes, they can be used in a wider range of applications, opening new door to other technology. But, as it is still under development, many testing methods are necessary to measure and record how solid-state batteries perform as they charge and discharge. Most important are the structural and morphological changes in the near-atomic scale. One such method is XRD, x-ray diffraction, which can penetrate deep into test cells as they cycle. It can non-destructively provide essential data on structural changes in the electrodes. The Dasgupta research group has an XRD measurement system but not a solid-state battery staging device; it only has that for liquid cells. Although they were available, it was a more efficient use of resources to repurpose the liquid cell stage to hold solid-state cells by creating our own stage that attaches to the liquid cell stage. After taking measurements of the current liquid stage and referring to solid-state cell stages on the market, the first step was designing the new stage through CAD software. Then, it was 3D printed as a prototype to see how it fits together and look for improvements. Once the final design was completed, a manufacturing team of the Dasgupta group produced it to its specifications. Now, the Dasgupta Group has a working solid-state battery cell stage for XRD testing, which opens many new outlets for research.
