Vanadiumkosten für die Energiespeicherung von All-Vanadium-Redox-Flow-Batterien
Redox-Flow-Batterien sind hochflexible Geräte, bei denen die Energie in den Elektrolyten gespeichert wird, die die elektroaktiven Vanadiumspezies enthalten. Diese Elektrolyte befinden sich in externen Tanks und fließen durch die Wirkung von Hydraulikpumpen in die Batteriezellen, wo die elektrochemischen Oxidations-Reduktionsreaktionen stattfinden.
