Abstract: L'invention concerne une batterie à flux d'oxydoréduction (RF) qui présente une densité d'énergie améliorée. L'invention concerne en particulier une batterie à flux RF (100) qui est chargée et déchargée en fournissant respectivement une solution d'électrolyte d'électrode positive et une solution d'électrolyte d'électrode négative à une cellule d'électrodes positives (102) et à une cellule d'électrodes négatives (103). La solution d'électrolyte d'électrode positive et la solution d'électrolyte d'électrode négative contiennent toutes les deux des ions vanadium (V) comme matériau actif. La solution d'électrolyte d'électrode positive et/ou la solution d'électrolyte d'électrode négative contiennent de plus d'autres ions métalliques, par exemple des ions métalliques tels que des ions manganèse qui présentent un potentiel supérieur à celui des ions V, ou des ions métalliques tels que des ions chrome qui présentent un potentiel inférieur à celui des ions V. Même dans des cas où l'état de charge de la batterie à flux RF (100) est proche de 100 %, des réactions secondaires telles que la génération d'un gaz d'oxygène ou d'un gaz d'hydrogène due à la décomposition d'eau, ainsi que la dégradation de l'oxydation d'une électrode peuvent être supprimées du fait que les ions d'autres métaux mentionnés ci-dessus, contenus en même temps que les ions V, sont oxydés ou réduits à la fin de la charge. Du fait que le rendement de l'utilisation d'ions V dans la solution d'électrolyte peut être augmenté en améliorant l'état de charge, la batterie à flux RF (100) présente une densité d'énergie améliorée en comparaison avec des batteries à flux RF classiques.
