Title
(EN) SMALL ORGANIC MOLECULE BASED FLOW BATTERY
(FR) ACCUMULATEUR À CIRCULATION À BASE DE PETITES MOLÉCULES ORGANIQUES
Abstract
(EN)
The invention provides an electrochemical cell based on a new chemistry for a flow battery for large scale, e.g., gridscale, electrical energy storage. Electrical energy is stored chemically at an electrochemical electrode by the protonation of small organic molecules called quinones to hydroquinones. The proton is provided by a complementary electrochemical reaction at the other electrode. These reactions are reversed to deliver electrical energy. A flow battery based on this concept can operate as a closed system. The flow battery architecture has scaling advantages over solid electrode batteries for large scale energy storage.

L'invention concerne une cellule électrochimique basée sur un nouveau procédé chimique pour un accumulateur à circulation destiné à un stockage d'énergie électrique à grande échelle, par ex. à l'échelle d'un réseau. L'énergie électrique est stockée chimiquement dans une électrode électrochimique par la protonation de petites molécules organiques appelées quinones en hydroquinones. Le proton est fourni par une réaction électrochimique complémentaire au niveau de l'autre électrode. Ces réactions sont inversées pour fournir de l'énergie électrique. Un accumulateur à circulation basé sur ce concept peut fonctionner comme un système fermé. L'architecture de l'accumulateur à circulation présente des avantages d'échelle par rapport à des accumulateurs à électrode solide pour le stockage d'énergie à grande échelle.
