]]> Sodium–sulfur (Na–S) batteries are promising for sustainable energy storage, but their performance is often limited by operational instability. In this study, we investigate sulfurized polyacrylonitrile (SPAN) as a cathode material and show that the depth of discharge plays a critical role in battery stability.
We find that deep discharge below 1.0 V causes structural changes in SPAN, leading to the formation of soluble polysulfides. These species migrate to the sodium anode, triggering side reactions, uneven sodium deposition, and dendrite growth. As a result, the battery experiences a loss of capacity and reduced lifespan.
By limiting the discharge range, these degradation processes can be minimized, preserving both the structure of the cathode and the overall performance of the battery. This work highlights the importance of optimizing operating conditions to achieve stable and efficient Na–S batteries.

]]> The Minisymposium on Polymeric Sustainable Materials took place on 20th March 2026 at the Karlsruhe Institut of Technology.

The symposium was organized within the framework of the EPICUR University Alliance SUSPHOTOPOLY initiative – a day that brought together inspiring scientists and fresh perspectives across polymer chemistry.

The EPICUR project not only supported that all enrolled M1 students join the symposium but also 6 PhD students from IS2M were additionally supported.
