Researchers in China have proposed a new strategy to bring aqueous sulfur-based redox flow batteries closer to commercial production. The technology uses polysulfide, a promising material for electrolytes, but its poor battery lifecycle due to polysulfide crossover has hindered its development. To overcome this challenge, the researchers have outlined an integrated strategy focused on catalyst design, ion-selective membranes, and device integration. The goal is to achieve a competitive levelized cost of storage for long-duration energy storage.
The researchers believe that by improving catalyst design, ion-selective membranes, and device integration, they can resolve the issues associated with sulfur-based flow batteries. The strategy aims to provide a competitive and feasible solution for the industrialization of this energy storage technology. According to the corresponding author, Dongliang Chao, the proposal targets the commercialization of sulfur-based flow batteries, with the potential to offer a cost-effective and sustainable solution for long-duration energy storage.
