Title (EN) RECHARGEABLE COPPER OXIDE ELECTRODES FOR ELECTROCHEMICAL APPLICATIONS
(FR) ÉLECTRODES D’OXYDE DE CUIVRE RECHARGEABLES POUR APPLICATIONS ÉLECTROCHIMIQUES
Abstract:
(EN) A rechargeable electrochemical battery is disclosed. The battery includes a cell container; a positive electrode comprising a positive electrode active material; a negative electrode comprising a negative electrode active material; a separator disposed between the positive and negative electrodes; and an electrolyte comprising an alkaline aqueous solution. One of the positive electrode active material or the negative electrode active material comprises a copper oxide-based material and a bismuth-based additive. The rechargeable electrochemical battery includes bismuth additives and formulations of copper oxide-based electrodes that allow for the copper oxide-based material to be electrochemically cycled in alkaline electrolyte.
(FR) L’invention concerne une batterie électrochimique rechargeable. La batterie inclut un récipient de piles ; une électrode positive comprenant un matériau actif d’électrode positive ; une électrode négative comprenant un matériau actif d’électrode négative ; un séparateur disposé entre les électrodes positive et négative ; et un électrolyte comprenant une solution aqueuse alcaline. Un matériau parmi le matériau actif d’électrode positive ou le matériau actif d’électrode négative comprend un matériau à base d’oxyde de cuivre et un additif à base de bismuth. La batterie électrochimique rechargeable inclut des additifs au bismuth et des formulations d’électrodes à base d’oxyde de cuivre qui permettent un cycle électrochimique du matériau à base d’oxyde de cuivre dans l’électrolyte alcalin.
