Title (EN) AIR-BREATHING AQUEOUS SULFUR RECHARGEABLE BATTERIES
(FR) BATTERIES RECHARGEABLES AU SOUFRE AQUEUX AÉROBIES
Abstract:
(EN) 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.
(FR) L'invention concerne un appareil électrochimique comprenant un catholyte, un anolyte et un séparateur disposé entre le catholyte et l'anolyte. Le catholyte comprend un sel métallique dissous dans l'eau, fournissant ainsi au moins un ion métallique. L'anolyte comprend une solution de polysulfure. Le séparateur est perméable audit ou auxdits ions métalliques. Pendant un processus de charge de l'appareil électrochimique, de l'oxygène est généré dans le catholyte, le polysulfure dans la solution de polysulfure subit une réaction de réduction dans l'anolyte, et ledit ou lesdits ions métalliques passent du catholyte à l'anolyte. Pendant un processus de décharge de l'appareil, l'oxygène est consumé dans le catholyte, le polysulfure s'oxyde dans l'anolyte, et ledit ou lesdits ions métalliques passent de l'anolyte au catholyte.
