Abstract
Various current collectors for redox flow batteries are described. The current collectors include at least one metal plate encapsulated in a conductive polymer end plate, the metal plate to the back of a stack end plate with a conductive adhesive, and a flat metal plate having deformable tabs. Battery flow systems incorporating the current collectors are also described. Battery flow systems with easily replaceable current collectors are also described.
Claims7
A current collector for a flow battery comprising:
- at least one conductive metal plate encapsulated in a conductive polymer end plate wherein the at least one conductive metal plate comprises a plurality of individual conductive metal plates encapsulated in the conductive polymer end plate.
A redox flow battery system comprising:
- at least one rechargeable cell comprising a positive electrolyte, a negative electrolyte, a separator positioned between the positive electrolyte and the negative electrolyte, the positive electrolyte in contact with a positive electrode, and the negative electrolyte in contact with a negative electrode, a first current collector in electrical communication with the negative electrode, and a second current collector in electrical communication with the positive electrode;
- wherein the first current collector or the second current collector, or both comprises at least one conductive metal plate encapsulated in a conductive polymer end plate wherein the at least one conductive metal plate comprises a plurality of individual conductive metal plates encapsulated in the conductive polymer end plate.
