Title: Air-breathing aqueous sulfur rechargeable batteries

Abstract

An electrochemical apparatus includes a catholyte, an anolyte, and a separator disposed between the catholyte and the anolyte. The catholyte includes metal salt dissolved in water, thereby providing at least one metal ion. The anolyte includes a polysulfide solution. The separator is permeable to the at least one metal ion. During a charging process of the electrochemical apparatus, oxygen is generated in the catholyte, the polysulfide in the polysulfide solution undergoes a reduction reaction in the anolyte, and the at least one metal ion moves from the catholyte to the anolyte. During a discharging process of the apparatus, the oxygen is consumed in the catholyte, the polysulfide oxidizes in the anolyte, and the at least one metal ion moves from the anolyte to the catholyte.
