Title
(EN) REDOX FLOW BATTERY AND NEW COMPOUNDS USEFUL THEREIN
(FR) BATTERIE À FLUX REDOX ET NOUVEAUX COMPOSÉS UTILES DANS CELLE-CI
Abstract
(EN)
The present invention relates to a redox flow battery comprising: a positive compartment containing a positive electrode in contact with a first aqueous-based electrolyte solution comprising a positive electrolyte dissolved in a first aqueous-based solvent; a negative compartment containing a negative electrode in contact with a second aqueous-based electrolyte solution comprising a negative electrolyte being an organic redox-active molecule dissolved in a second aqueous-based solvent; means for establishing electrical conduction between said positive electrode and said negative electrode, and an external load for directing electrical energy into or out of the redox flow battery; a separator component that separates the first aqueous-based electrolyte solution in the positive compartment from the second aqueous-based electrolyte solution in the negative compartment and substantially prevents the positive electrolyte in the positive compartment and the negative electrolyte in the negative compartment from intermingling with each other, while permitting the passage of non-redox-active species between the electrolyte solutions in the positive and negative compartments; and means capable of establishing flow of the electrolyte solutions past said positive and negative electrodes, respectively, and wherein the organic redox-active molecule is a naphthalene diimide (NDI); and a modified NDI.

La présente invention concerne une batterie à flux redox comprenant : un compartiment positif contenant une électrode positive en contact avec une première solution électrolytique à base aqueuse comprenant un électrolyte positif dissous dans un premier solvant à base aqueuse ; un compartiment négatif contenant une électrode négative en contact avec une seconde solution électrolytique à base aqueuse comprenant un électrolyte négatif qui est une molécule active-redox organique dissoute dans un second solvant à base aqueuse ; des moyens pour établir une conduction électrique entre ladite électrode positive et ladite électrode négative, et une charge externe pour diriger de l'énergie électrique dans ou hors de la batterie à flux redox ; un composant séparateur qui sépare la première solution électrolytique à base aqueuse dans le compartiment positif de la seconde solution électrolytique à base aqueuse dans le compartiment négatif et empêche sensiblement l'électrolyte positif dans le compartiment positif et l'électrolyte négatif dans le compartiment négatif de se mélanger l'un avec l'autre, tout en permettant le passage d'espèces actives non-redox entre les solutions électrolytiques dans les compartiments positifs et négatifs ; et des moyens aptes à établir un écoulement des solutions électrolytiques au-delà desdites électrodes positive et négative, respectivement, et la molécule active redox organique étant un diimide de naphtalène (NDI) ; et un NDI modifié.
