Summary: Gel polymer electrolytes (GPEs) based on poly(vinylidene difluoride) (PVdF) are promising for high-performing lithium-sulfur batteries (LSBs), but their stability with lithium metal (Li-0) anode is a major drawback. This study investigates the stability of PVdF-based GPEs with Li-0 and their application in LSBs. The introduction of lithium nitrate in the electrolyte significantly improves the capacity retention of the GPEs. The study emphasizes the need for anode protection processes when using PVdF-based GPEs in LSBs.
