Polysulfide is one of the most promising materials for electrolytes used in large-scale aqueous redox flow batteries (RFBs) due to its inherent safety, high energy and low cost. However, potential polysulfide crossover results in a poor battery lifecycle, which prevents sulfur-based flow batteries from getting closer to commercialization.
With this in mind, a group of researchers in China has outlined a new pathway for the industrialization of this energy storage technology, which promises a competitive levelized cost of storage for long-duration energy storage. “In our work, we proposed an integrated strategy targeting sulfur-based flow battery commercialization, focusing on catalyst design, ion-selective membranes, and device integration,” the research's corresponding author, Dongliang Chao, told pv magazine.
