Comparing Lithium and Sodium-Ion Battery Degradation Using Non-Destructive X-Ray Scans

The objective of this research is to analyze the behavior of lithium and sodium-ion cells cycled at slow rates in extreme temperatures, since cells tend to malfunction in said conditions. The research is performed through a characterization process, analyzing the capacity and charge curves as well as with the help of CT scans of the cells. CT scans are non-destructive X-rays on the cells that help in understanding the performance of the batteries has applications in repurposing obsolete batteries, comparing sodium-ion battery as a more sustainable alternative to lithium and finding how performance in extreme temperatures could be improved.
