A redox flow battery comprising:
- A cell divided into half-cells by a membrane;
- wherein each half-cell comprises a current collector and an electrode element arranged in an interior of the respective half-cell;
- an electrolyte able to flow through the interior of the respective half-cell;
- an electrode;
- and
- a guide structure for guiding the electrolyte integrated into and defined by the associated electrode, wherein the guide structure includes multiple regions defined by different densities among the multiple regions and at least one of the multiple regions is defined by stitches in the guide structure.
