Title (EN) METHODS AND SYSTEMS FOR OPERATING A REDOX FLOW BATTERY SYSTEM
(FR) PROCÉDÉS ET SYSTÈMES DE FONCTIONNEMENT D'UN SYSTÈME DE BATTERIE À FLUX REDOX
Abstract:
(EN) A method of operating a redox flow battery, may include maintaining a positive electrode compartment pressure greater than a negative electrode compartment pressure, and maintaining a cross-over pressure less than a membrane break-through pressure, wherein the cross-over pressure equals the negative electrode compartment pressure subtracted from the positive electrode compartment pressure. In this way, ionic resistance across the separator can be maintained at a lower level by reducing gas bubbles trapped therein while reducing separator break-through, thereby increasing performance of the redox flow battery system.
(FR) L'invention concerne un procédé de fonctionnement d'une batterie à flux redox pouvant comprendre le maintien d'une pression de compartiment d'électrode positive supérieure à une pression de compartiment d'électrode négative, et maintenir une pression transversale inférieure à une pression de rupture de membrane, la pression transversale étant égale à la pression de compartiment d'électrode négative soustraite de la pression de compartiment d'électrode positive. De cette manière, la résistance ionique à travers le séparateur peut être maintenue à un niveau inférieur en réduisant les bulles de gaz piégées dans celle-ci tout en réduisant la rupture du séparateur, ce qui permet d'augmenter les performances du système de batterie à flux redox.
