Abstract

L'invention concerne un procédé d'équilibrage d'une batterie à flux redox déséquilibrée ayant un électrolyte négatif partiellement oxydé, comprenant les étapes consistant à : mesurer l'étendue d'oxydation de l'électrolyte négatif, et; ajouter un agent réducteur à l'électrolyte positif pour réduire les ions V5+/ [V02]+ aux ions V4+/[VO]2+ l'agent réducteur combinant le carbone, l'oxygène et l'hydrogène dans des rapports tel que les produits de la réaction comprennent des ions V57 [V02]+, réduit en ions V4+/ [VO]2+, eau et dioxyde de carbone. L'agent réducteur pouvant être un acide carboxylique ou un précurseur, ou bien un produit intermédiaire, d'un acide carboxylique.
