Abstract
To compete with the thriving economy and the increasing demand for green energy, Li-ion batteries have been proven to be incapable of satisfying current demands in the automation industry due to their limited capacity and energy density. As a result, the application of Li-S batteries has emerged and attracted experts both within academia and the industry, especially with its ability to store and provide an extensive amount of energy compared to that of traditional Li-ion batteries. However, Li-S batteries experience electrochemical dissolution, causing corrosion and poor electronic conductivity. This study focuses on analyzing seven crystals within the polysulfide shuttle in Li-S batteries and observing their respective emission energies through X-Ray emission spectroscopy. Using the software ORCA, an analysis on these results reveals that the emission spectrums among the crystals all consist of different in k-alpha and k-beta values. As the commercialization process and introduction of Li-S batteries into the world market is proceeding at a slow pace, this project aims to provide critical data and information on Li-S crystals for future research on similar topics.
