Definitions
- the present invention relates to a profiled strip, an electrochemical energy storage device with this profiled strip, a battery with these electrochemical energy storage devices and a method for producing this profiled strip.
- the invention will be described in connection with lithium-ion batteries for the supply of motor vehicle drives. It should be noted, however, that the invention may also be used regardless of the type of battery or regardless of the type of powered drive.
- An electrochemical energy storage device contains reactive substances, safe operation is therefore possible only if uncontrolled reactions of these reactive substances, e.g. with the environment, be prevented.
- the enclosure of an electrochemical energy storage device separates the reactive materials within the enclosure from the environment surrounding the enclosure. This prevents the coating from uncontrolled substances from the electrochemical energy storage device off or enter this.
- the sheathing on the one hand supports the safe operation of the electrochemical energy storage device and on the other hand protects the environment from contamination by substances from the electrochemical energy storage device.
- a particularly endangered area of this enclosure is its edge area. By a device which at least reduces external stresses on this endangered region of the envelope, the safety of an electrochemical energy storage device can thus be improved.
- Batteries having a plurality of electrochemical energy storage devices for supplying vehicle drives are known. Some types have in common that the environment of these batteries is at risk of failure of an electrochemical energy storage device with leakage of the cell contents.
- the invention is therefore based on the object to increase the safety of the electrochemical energy storage device.
- the profile strip according to the invention is preferably used to protect the boundary of an electrochemical energy storage device.
- the profile strip has at least one, extending substantially in the longitudinal direction, first slit. This slot is bounded by a first leg and a second leg. These first and second legs are designed so that they can be applied to opposite sides of an edge region of the electrochemical energy storage device.
- An electrochemical energy storage device comprises at least one electrode stack, a current conductor, which is electrically conductively connected to the electrode stack, an envelope made of a thin-walled composite material which at least partially surrounds the electrode stack and has at least one boundary in its edge region.
- a profiled strip according to the invention covers at least a portion of this enclosure.
- a battery according to the invention includes at least two electrochemical energy storage devices. These electrochemical energy storage devices are preferably arranged substantially parallel to one another and have profile strips according to the invention in the edge region of their coverings. In this case, these profile strips according to the invention are designed so that the sheaths of the energy storage devices exert substantially no forces on each other.
- the electrochemical energy storage devices are intended to be electrically interconnected.
- An inventive method for producing a profile strip for an electrochemical energy storage device is characterized by various manufacturing steps. At least one first recess is introduced by a suitable method into the profiled strip according to the invention. The shape of this first recess preferably has a substantially triangular shape. This first recess is intended to bend the profile strip according to the invention. By the angle of the profile strip according to the invention, this is transferred from a first straight to a second angled state. The process of Abwinkeins is carried out so that the tensile strength of the profile strip according to the invention is not exceeded.
- the electrochemical energy storage device has at least one profile strip.
- a profile strip in the context of the invention is preferably a substantially thin-walled body, which preferably consists of an electrically insulating material or of a material coated at least with an electrically insulating layer material to understand.
- This profile strip has at least in one or more areas on a defined cross-sectional area.
- this cross-sectional area has a first leg, a second leg and a back part. Preferably connects this back part of this first leg with this second leg.
- This first limb preferably lies substantially opposite this second limb. Both legs covered a first slit. This first leg preferably forms with this second leg and this back part a substantially U-shaped, thin-walled main body.
- the profile strip consists of only one component.
- the profile strip consists of several components, preferably a first leg, a second leg and a back part. Preferably, these components are positively or materially connected to each other.
- the profile bar is preferably formed in a shape adjacent to the edge region.
- the profiled strip is produced either in one, at least partially, adapted to this portion of the edge region expression or the profile strip is transferred from a first stretched state into a second one or more times angled state.
- it is provided with one or more first recesses.
- the profiled strip can at least partially cover the edge region of the sheath marked by corners or radii.
- first recess Under a first recess is a material-free space to understand the profile strip, which extends starting at the first slot in the direction of this back part. In a preferred embodiment, this first recess has a substantially triangular shape. Such a first Recess is generally known from window or picture frames and is referred to as a miter cut.
- the profile strip In its second state, the profile strip has at least one kink. Viewed in the longitudinal direction before and after this kink, the profile strip extends at least partially rectilinear.
- An electrochemical energy storage device has at least one electrode stack, a current conductor, a cover and a profile strip.
- An electrode stack is to be understood as an arrangement having at least two electrodes and an electrolyte arranged in each case between two electrodes.
- An electrode stack serves to store chemical energy and convert it into electrical energy. Conversely, the electrode stack can also be used to convert electrical energy into chemical energy, if it is a rechargeable battery.
- the enclosure means a device which also prevents the escape of chemicals from the electrode stack into the environment.
- the sheath preferably protects the chemical constituents of the electrode stack from undesirable interaction with the environment.
- the sheath protects the electrode stack from the ingress of water or water vapor from the environment.
- the envelope is formed like a film. The coating should affect the passage of heat energy as little as possible.
- the enclosure has one or more moldings, preferably two moldings.
- the envelope is at least partially adapted to the shape of the electrode stack and encloses it.
- the term "enclosing” is to be understood as meaning that one or more molded parts of the covering are brought into contact with a second molded part or with itself in certain areas.
- the electrode stack comes between the involved surfaces of the moldings to lie. This one or more mold parts contact each other areally, preferably at least along an edge region delimiting the envelope or a boundary of one or more involved moldings.
- boundary of the immediate edge region of the enclosure For the purposes of the invention is to be understood as boundary of the immediate edge region of the enclosure.
- the boundary runs around the envelope.
- the conductors are guided by the boundary of the electrode stack from the interior of the enclosure to the outside.
- a current conductor is to be understood as a device which essentially enables the flow of electrons between an electrode and an electrical consumer.
- a current collector is electrically connected to an electrode or an active electrode mass of the electrode stack and further to a connection cable.
- the shape of the current conductor is adapted to the shape of the electrochemical energy storage device or of the electrode stack.
- a current collector is plate-shaped or foil-like.
- Each electrode of the electrode stack preferably has its own current conductor or the electrodes of the same polarity are connected to a common current conductor.
- the profile strip is preferably mounted in the region of the boundary to the enclosure.
- the profile strip covers an area of the enclosure, in which touch the surfaces of one or more of these moldings. External stresses no longer act directly on this boundary, but on the profile strip.
- the edge region of the enclosure is at least partially relieved.
- the profile strip In the transition region from the profile strip to the envelope, the profile strip preferably has at least one broken or rounded edge. As a result of this design of this edge, the contact stresses which are induced by the profiled strip in the enclosure are opposite a sharp-edged one Expression, reduced. By reducing the contact stresses in the enclosure, an increase in security against uncontrolled discharge of material from the envelope and an uncontrolled material entry into the envelope is achieved.
- the profile strip has a substantially U-shaped cross-section and covers the entire boundary of the enclosure. Substances that emerge from the enclosure in the area of the boundary first reach the profile strip and thus can not interact directly with the surroundings. Thus, the safety of the electrochemical energy storage device is further increased.
- the profile strip is designed with a substantially U-shaped cross-section.
- this cross section is preferably designed so that the distance between two legs which are at least partially opposite one another is smaller than the thickness of the envelope in the region of its boundary.
- the regions of the U-shaped profile strip with the at least partially opposite first and second legs thus exert a normal force on the surface of the envelope in the region of the boundary.
- the normal force is essentially directed in such a way that it presses two surface areas of the envelope in the vicinity of the boundary at least partially against each other.
- the profile strip is connected to the envelope cohesively.
- a cohesive connection is preferably the bonding of the enclosure with the profile strip or the welding to understand.
- the profile strip has a second recess.
- the second recess is intended to guide a current conductor therethrough.
- the shape and number of the second recesses is substantially equal to the shape and number of current conductors.
- one or more current conductors are passed through one or more second recesses.
- a current conductor is preferably guided through a second recess. In the region of the second recess, the current conductor is connected to the profile strip in a force, material or form-fitting manner.
- the forces acting on the current conductor from the outside are at least partially absorbed by the profile strip. By this force deflection of the area in which the current arrester passes through the enclosure, mechanically relieved. Likewise, the area in which the current conductor is connected to the electrode stack is relieved. By relieving these connection areas, the safety of the electrochemical energy storage device is increased.
- a battery is understood to mean a device which has two or more electrochemical energy storage devices.
- the electrochemical energy storage devices contained in such a battery are preferably equipped with profiled strips according to the invention. Especially the safety of the energy storage devices is increased by these profile strips.
- the cross-sectional area of the profiled strip is preferably designed so that at least the sheaths of two substantially mutually parallel arranged electrochemical energy storage devices exert no forces directly on each other.
- a force acting on the envelope the pressure within the electrochemical energy storage device increases.
- the wrapper is stressed by a force applied thereto and by the pressure caused in the wrapper. Reducing an external force on the enclosure by a profiled strip thus increases the safety of the electrochemical energy storage device.
- the cross-sectional area of the profiled strip is preferably designed so that two substantially mutually parallel energy storage devices can be positively, force and / or materially connected by their profile strips.
- the profile strips of two adjacent electrochemical energy storage devices preferably form a common connection region. In this connection region, two adjacent profiled strips are at least partially cohesively or preferably non-positively connected or particularly preferably positively connected to each other.
- this type of connection at least two electrochemical energy storage devices easily form a structural unit. The simple construction of such a mechanical unit helps increase the safety of the electrochemical energy storage device.
- the cross-sectional area of a profiled strip is designed such that two electrochemical energy storage devices arranged essentially parallel to one another can be connected to form a structural unit by means of a connecting element.
- a connecting element with at least one profiled strip forms a connecting region.
- the connecting element with the profile strip in this connection area at least partially cohesively or preferably non-positively or particularly preferably positively connected.
- a separating element is preferably positioned. The separator preferably contacts the enclosure of at least one electrochemical energy storage device.
- the connecting element is preferably cohesively or preferably positively connected or particularly preferably non-positively connected to the separating element.
- a heat conduction from the enclosure of the electrochemical energy storage device is achieved by this separating element to this connecting element.
- a method for producing a profiled strip for an electrochemical energy storage device is to introduce a first recess into the profiled strip, the angle of the profiled strip and, optionally, to connect the cut surfaces of this first recess.
- the shape of the first recess and the process of folding over are preferably designed so that the tensile strength of the profile strip is not exceeded.
- the profile strip can be heated to fold.
- the profile strip remains as a one-piece element.
- the one-piece design of the profile strip simplifies the handling of the profile strip during assembly on the enclosure.
- the resulting corner joint preferably by adhesive bonding or particularly preferably by welding materially connected.
- the cohesive connection of one or more corner joints increases the rigidity of the profile strip. On the profile strip applied externally stresses are thus, compared to a profile strip with not material or positively connected corner joints, better absorbed by this and less strong passed on to the enclosure.
- the cohesive connection of one or preferably a plurality of corner joints improves the sealing of the electrochemical energy storage device. The increased rigidity and the improved sealing of the profiled strip by the described type of production thus increase the safety of the electrochemical energy storage device.
- the escape of the contents of the electrochemical energy storage device according to the invention is prevented, prevents the access of an undesirable substance in the electrochemical energy storage device and solved the underlying object.

- the separating element 19 contacts the sheaths 15 of the two electrochemical energy storage devices 2 and is non-positively connected to the connecting element 20.
- temperature flows from at least one sheath 15 off or fed to a sheath 15.
- the temperature balance is thus improved mainly in the region between two electrochemical energy storage devices 2.
- the construction of a block of a plurality of electrochemical energy storage devices 2 with improved temperature management is made possible in a simple manner.
