Definitions
- the present invention relates to a method for producing a marking, a method for producing an energy storage cell and a motor vehicle.
- Energy storage cells of the type in question are, for example, lithium-ion battery cells. Regardless of the cell type, the smallest unit of such energy storage cells consists of two electrodes and a separator that separates the electrodes from one another. In between is the conductive electrolyte.
- the electrodes are typically formed by coated carrier foils.
- the coating materials for the anode and the cathode are usually different, but they essentially contain the components active material, conductive carbon black, solvent, binder and other additives.
- the carrier foils are preferably metallic, sheet-like foils which are initially in the form of rolls. In production, it is often necessary to ensure a certain level of traceability, for example for quality assurance.
- the uncoated edge areas of the carrier foils can be provided with a colored marking or the like.
- the markings are also lost.
- a colored marking of the coating itself is excluded in order not to negatively influence the electrochemical properties of the cell.
- a method for producing a marking comprises the steps: - Application of coating material to a carrier material;
- the method advantageously uses the fact that components of the coating material can be knocked off or knocked off by applying a magnetic field, for example by means of a magnetic device such as an (electro-magnet).
- a magnetic device such as an (electro-magnet).
- the resulting (re)alignment of these components can result in structuring of the coating material, which leads to an optical change, in particular to a surface of the coating material, in such a way that it can be used and perceived as a marking.
- Information can advantageously be generated and transmitted via the optical change in the coating. Alternatively, such a mark can also be used as a design element.
- a material If a material is exposed to an external magnetic field, the material becomes magnetized.
- the direction and strength of this magnetization is based on intrinsic properties of the material and is characterized by the terms diamagnetism, paramagnetism and ferromagnetism.
- the magnetization of matter in an external field i.e. the alignment of the elementary magnets in the material, can be in the opposite direction to or in the same direction as the external magnetic field.
- diamagnetism the magnetization is in the opposite direction to the external field.
- paramagnetic bodies the magnetization is in the same direction as the external magnetic field.
- the magnetization In ferromagnetic materials, the magnetization is in the same direction as the external magnetic field and is particularly strong due to a special interaction of the electron spins, the so-called exchange interaction. With the same external magnetic field, the magnetization of ferromagnetic materials is generally significantly greater than the magnetization of paramagnetic materials.
- the present method is independent of the underlying principle.
- the method is used to mark an electrode of a battery cell, such as a lithium-ion battery/accumulator.
- the carrier material is designed as a metallic, sheet-like foil.
- a backing film for the anode is typically around a copper foil, in the case of the carrier foil for the cathode typically around an aluminum foil.
- the coating can be on one or both sides, intermittently or continuously.
- the components mentioned are graphite particles.
- the graphite particles are part of the coating.
- Graphite is diamagnetic. It has been shown that, for example, after the setting of a magnetic field, the coating is darker in the area of converging field lines than in the area without a magnetic field. It is thus advantageously possible to produce markings, structures and/or structuring, etc., by allowing a magnetic field (or several) to take effect in a targeted manner.
- a magnetic device is used to create a magnetic field and to align the components.
- the method comprises the step:
- electromagnets are used to align the components.
- the method is carried out in such a way that the magnetic field acts directly and immediately on the respective coated area.
- the magnetic field acts, so to speak, from the opposite side of the area just coated.
- the strength of the magnetic field can be used to set, among other things, whether the marking or a marking is produced on both sides of the (both sides) coated carrier material.
- the method comprises the step:
- the magnetic components can be aligned.
- the method comprises the step: - Analysis of the coating process and/or optical detection and evaluation of the coating to determine the position of the at least one marking.
- the information of an application tool, via which the coating is applied is recorded and processed. If necessary, it can already be recognized that there was an error in the coating process. Additionally or alternatively, the coating can be detected and checked by means of optical detection devices, such as cameras, in order to identify whether there is a fault. These or optionally several points can then advantageously be marked with precise positioning via the magnetic device.
- the method comprises the step:
- the marking is advantageously applied directly to the coating, it can be used throughout the manufacturing and production process, for example for component tracking. This brings great advantages in terms of flexibility of the application.
- the method comprises the step:
- the web meters of film roll/electrode roll used can be traced down to the cell level.
- the method comprises the step:
- the influence on the electrochemistry which may be caused by the alignment of the magnetic components, can be reduced to a minimum.
- one or more markings can also be provided in other areas of the coating, for example also in the middle, in particular if a fault has been detected at this point anyway.
- the method comprises the step: Fix the mark.
- a protective layer such as a clear lacquer.
- the (coated) carrier material is not intended for use in a galvanic element, but rather as a design element, for example in a vehicle interior, the structure/marking can be permanently retained.
- the invention also relates to a method for producing an energy storage cell, the method according to the invention for producing a marking being used within the scope of manufacture or manufacture.
- the invention also relates to a motor vehicle which comprises at least one energy storage cell which was produced using the method according to the invention.
- Typical motor vehicles of the type in question are, for example, hybrid vehicles or fully electrically operated vehicles, which can be motorcycles, passenger cars, but also commercial vehicles.
- Fig. 2 a schematic representation of an embodiment of a procedural procedure for producing an energy storage cell.
- FIG. 1 shows a schematic representation of a plan view of a carrier material 10, which can be a metal carrier foil, for example, which is moved along a path direction B.
- the carrier material 10 has a coating or is coated with a coating material 20 . It can be seen that markings 40 are provided in the edge areas of the coating. These were created by aligning components in the coating material 20 . This makes it possible, for example, to trace the linear meters of carrier material 10 used down to the cell level.
- FIG. 2 shows a schematic view of a coating process, a carrier material 10 being coated with coating material 20 via an application tool 60 . The carrier material 10 is moved along a web direction B.
- a quality of the coating material or the coating application is evaluated via a detection device 62, for example an optical detection device, for example comprising one or more cameras.
- the detection device 62 is connected to a magnetic device 64, cf. reference number 50.
- the magnetic device 64 can mark the corresponding fault in the exact position, cf. reference number 40 recognized later and, for example, removed or reworked.
