Among various types of rechargeable batteries, metal sulfur and aqueous battery have been considered as the most promising next-generation energy storage devices owing to the high theoretical specific capacity of sulfur cathode and nonflammability of water solvent, respectively. Where the insulating nature of sulfur and its reductive derivatives along with the uncontrollable migration of polysulfides hinder the commercialization of metal-sulfur technology, aqueous batteries mostly suffers from the narrow electrochemical stability window of water-based electrolyte. In this presentation few strategies to overcome the above-mentioned difficulties will be addressed.
