Abstrakt

Lithium-Sulfur (Li-S) batteries represent one of the possible development pathways of Lithium based batteries, as they are expected to provide benefits of high volumetric energy density, various safety features, and low production cost. In order to use them efficiently in practical applications, it is necessary to fill the wide knowledge gap about Li-S performance, especially at the size of commercial cells. The current study analyzes the long-term shelf storage behavior of pouch cells at various conditions of temperature and state-of-charge, by periodically monitoring the battery cell’s performance parameters. Based on the obtained results, we have observed that especially the cells’ resistance exhibited a complex behavior, when according to the applied storage conditions it has increased, decreased or remained constant over the storage period.
