Viklet redoxflowbatteri

The invention relates to a redox flow battery comprising at least one wound redox flow battery module (10a, 10b) having at least two half cells separated by at least one membrane film, through each of which fluid electrolytes (106, 107) flow, said electrolytes having a respective one of two redox active substances (101, 103) dissolved in a solvent, which interact with one another via a redox reaction, wherein the at least two separated half cells are formed by winding at least one first section (3a) of at least one membrane film, a section of at least one first electrically conductive deflection film (4a), at least one second section (3b) of the at least one membrane film, and a section of at least one second electrically conductive deflection film (4b) onto a central body (1), wherein respective flow channels (8a, 8b, 8c, 8d) are formed by at least one spacer (9) between the membrane film sections and deflection film sections after the winding.
