Definitions
- the present invention relates to an electrode module for a redox flow cell.
- the electrode module includes a frame in which an electrode is arranged.
- the invention further relates to a redox flow cell and a method for assembling an electrode module for the redox flow cell, wherein the assembly simultaneously leads to a sealing of an electrode in the electrode module.
- Redox flow cells Electric cells are known from the prior art, which are referred to as redox flow cells and with which redox flow batteries can be formed.
- Redox stands for reduction, in which electron acceptance can be seen.
- Ox stands for oxidation, in which electron loss can be seen.
- Redox flow cells store electrical energy in chemical compounds in which the reactants are dissolved in a solvent.
- Two energy-storing electrolytes circulate in two separate circuits, between which an ion exchange takes place in the cell via a membrane. The energy-storing electrolytes are preferably stored outside the cell in separate tanks.
- Redox flow cells preferably have a frame which frames a metal electrode of the cell.
- the frame represents a carrier frame for the electrode and is also used for sealing.
- a circumferential seal is required between the frame and the electrode. Since the electrolyte to be sealed is chemically aggressive, the choice of material for the seal is limited. The usual small wall thicknesses of the frame and the electrode also limit the selection of a suitable system for the sealing. Sealing solutions are known from the prior art, in which classic molded seals are used. These molded part seals are usually fixed by a groove in the frame. An undercut groove is required in the frame for a non-positive connection, which, due to the circumferential closed groove, leads to increased production costs.
- sealing profile can only be influenced to a limited extent. Sealing systems with molded part and FIP seals require an additional element to generate the seal preload. In addition, sealing composites with elastic adhesives are used. Due to the chemical aggressiveness of the electrolyte, the adhesive may be washed out. In addition, greatly differing thermal expansions of the frame, which is formed from a thermoplastic material, and the metallic electrode lead to severe shearing stresses in the adhesive bead, particularly in the case of large formats. Both effects significantly reduce the service life of such a sealing system.
- EP 2693087 A1 shows a sealing material for a thin plate element such as in a cell of a redox flow battery.
- the annular sealing material includes a side sealing body disposed on one side of the thin plate member.
- the front and the rear of the thin plate element are arranged on two sealing legs branching off from the lateral sealing body.
- WO 2014/198364 A1 shows an electrode module for a redox flow battery.
- the electrode module includes an electrode and a sealing frame.
- the electrode should be connected to the sealing frame in such a way that the resulting electrode module can be used in redox flow cells without any problems.
- the electrode is mechanically connected to the sealing frame.
- a multi-lip seal is preferably arranged on the sealing frame and rests against a membrane.
- the sealing frame preferably has a circumferential groove which is designed to taper conically towards the outside.
- the channel preferably has an undercut.
- WO 2013/016919 A1 shows a flow battery stack with a flow frame and with a collector plate arranged inside the flow frame.
- One Ion exchange membrane is placed between collector plates and forms a cavity in which an electrolyte is housed with the collector plate.
- An electrode is positioned within the cavity.
- Two sets of flow openings are formed on the sides of the flow frame.
- a sealing frame for use in a battery is known from EP 2432043 A1, which has a base body encompassing an opening.
- a trigger area is formed at an edge of the opening.
- a continuous drainage opening is formed in the base body adjacent to the triggering area.
- a cell with a cell housing is surrounded by a sealing seam. The cell is placed on the sealing frame in such a way that the cell housing extends into the opening in such a way that the sealed seam is in contact with the seal and that the sealed seam is not acted upon by the seal in the release area.
- At least one peripheral elastically compressible seal is provided, which encompasses the opening.
- EP 3 113272 A1 teaches a frame body for a cell of a redox flow battery.
- the frame body includes an opening formed within the frame body and a manifold through which an electrolyte can pass.
- a slit connecting the manifold and the orifice has a pair of side walls facing each other in a cross section orthogonal to a direction in which the electrolyte flows.
- the object of the present invention is to be able to fix an electrode for a redox flow cell in a frame in a simple and tight manner. Furthermore, thermal expansion should not lead to mechanical stresses that could impair the service life of the electrode.
- the electrode module according to the invention is intended for a redox flow cell.
- the redox flow cell is a wet cell and therefore an electrical accumulator.
- the redox flow cell stores electrical energy in chemical compounds, with the reactants being dissolved in a solvent in two energy-storing electrolytes.
- the two energy-storing electrolytes circulate in two separate circuits, between which an ion exchange takes place in the cell through a membrane.
- the redox flow cell is preferably formed by an organic flow cell made from non-toxic components.
- the redox flow cell is delimited by two electrodes.
- the electrodes are designed in the form of modules. Such a module is formed by the electrode module according to the invention.
- the electrode module includes a frame that forms a support frame and also a sealing frame.
- the frame includes a seal which is arranged on an inner circumference of the frame.
- the seal is formed circumferentially on this inner periphery of the frame.
- the seal has at least two inwardly directed elastic sealing lips.
- the sealing lips are directed towards the inside of the frame, i. H. to a center point of the frame, which is in a space enclosed by the frame.
- a circumferential groove is formed between two of the sealing lips.
- the circumferential groove is preferably formed between two adjacent sealing lips.
- the opening of the groove is oriented towards the inside of the frame, i. H. to the center of the frame.

- the electrode module also includes a metallic electrode.
- the electrode has an outer periphery with which the electrode sits in the groove of the gasket.
- the electrode protrudes into the groove of the seal so that it sits between the two sealing lips and is clamped by them. This holds, fixes and seals the electrode.
- the electrode protrudes into the groove along its circumferential direction over the entire length of the groove. As the electrode sits in the groove, it lies in the same plane as the frame and the seal. This level represents a main extension level of the frame, the seal and the electrode.
- the gasket encloses the electrode.
- the frame encloses the seal with the electrode seated therein.
- a particular advantage of the electrode module is that the seal allows both the sealing of the electrode and its storage.
- the electrode can be mounted quickly and easily in the frame, with a pre-tensioning force already being generated by the seal itself.
- the electrode can also be removed from the frame if required.
- one of the two sealing lips is pressed onto an upper side of the electrode, while the other of the two sealing lips is pressed onto an underside of the electrode.
- the electrode is thus force-fitted between the two sealing lips. This leads to the advantage that the electrode is fixed in a direction perpendicular to its main plane of extension and is also securely sealed.
- the outer perimeter of the electrode has circumferential clearance to a bottom of the groove.
- the bottom of the groove like the groove, is designed to be circumferential.
- a plumb line on the floor is preferably in the main plane of extension of the frame. This perpendicular preferably points to a center point of the frame.
- the soil envelops the outer circumference of the electrode, with a clearance, namely the said clearance, being given to the outer circumference of the electrode.
- the play leads to the electrode being able to expand and move somewhat in its main extension plane.
- the frame which is preferably made of a thermoplastic material, and the metal electrode have different coefficients of thermal expansion. The play prevents to a greater extent that the different thermal expansion coefficients lead to mechanical stresses when the temperature changes.
- the electrode is floating in the frame.
- the play is preferably at least as large as a thickness of the electrode.
- the clearance is more preferably at least five times the thickness of the electrode.
- one of the two sealing lips is designed as a snap-in lug, via which the electrode can be snapped into the groove.
- the sealing lip designed as a snap-in lug has an inner side face delimiting the groove and an outer side face opposite the inner side face.
- the outer side surface is inclined relative to the main plane of extent of the frame, so that when the electrode is inserted from outside the frame into the seal of the frame, the electrode can slide into the circumferential outer side surface of the sealing lip designed as a snap-in lug and this sealing lip folds over like a hinge in the direction of the groove up to the electrode gets into the groove via this sealing lip, whereupon this sealing lip snaps back like a hinge and comes to rest on the upper side of the electrode.
- the outer side face has an angle relative to the main extension plane of the frame which is preferably greater than 45°.
- the design of one of the two sealing lips as a snap-on lug has the advantage that the electrode can be inserted into the frame very quickly and with little effort.
- the sealing lip designed as a snap-in nose is also referred to below as the first sealing lip, while the other of the two sealing lips is referred to as the second sealing lip.
- the second sealing lip has an inner side face delimiting the groove and an outer side face opposite the inner side face.
- the outer side surface of the second sealing lip is preferably inclined with respect to the main plane of extent of the frame, but preferably less than the outer side surface of the first sealing lip. In an undeformed state, the outer side surface of the second sealing lip has an angle relative to the main plane of extension of the frame, which is preferably between 10° and 45°.
- the second sealing lip preferably protrudes further into the interior of the frame than the first sealing lip.
- the second sealing lip is in contact with the electrode in an area which is closer to the center point of the frame than an area in which the first sealing lip is in contact with the electrode.
- the second sealing lip in the main plane of extension of the frame has an extent which is preferably at least 1.5 times greater than an extent which the first sealing lip has in the main plane of extent of the frame. In this sense, the second sealing lip is preferably at least 1.5 times as high as the first sealing lip.
- the inclination of the outer side surface of the first sealing lip and the inclination of the outer side surface of the second sealing lip also lead to a self-sealing effect.
- a pressure acting on the electrode also acts on the outer side surface of the respective sealing lip, so that the area of this sealing lip that touches the electrode is pressed more strongly against the electrode.
- the seal is attached to the inner circumference of the frame in a form-fitting and/or material-fitting manner. This attachment ensures that the electrode seated in the seal is securely fixed and sealed against the frame.
- the seal is affixed as an injection molded part to the inner periphery of the frame.
