Description
Technical Field
The invention relates to a battery cell comprising a cell housing in which an electrode unit is arranged, wherein the electrode unit has an anode electrically connected to a negative terminal and a cathode electrically connected to a positive terminal, wherein the cell housing has a first housing part forming the negative terminal and a second housing part forming the positive terminal. In this case, insulating elements are provided which electrically insulate the housing parts from one another. The invention also relates to a method for producing a battery cell.
Background
The electrical energy can be stored by means of a battery. The battery converts chemical reaction energy into electrical energy. Here, the primary battery and the secondary battery are distinguished. Primary batteries have only a primary functional capability, while secondary batteries, also known as secondary batteries, can be recharged. In storage batteries, in particular so-called lithium ion battery cells are used. These lithium-ion-battery cells are characterized by, among other things, high energy density, thermal stability and minimal self-discharge.
A lithium-ion-battery cell has a positive electrode, also referred to as a cathode, and a negative electrode, also referred to as an anode. The cathode and the anode each include a discharger on which an active material is applied. The electrodes of the battery cells are constructed in a foil-like manner and are wound into electrode windings (elektrondenslicker) or stacked into an electrode stack having a plurality of electrode layers under an intermediate layer of a separator separating the anode from the cathode. The electrode and the separator are surrounded by a normally liquid electrolyte.
In addition, the battery cell has a cell housing, which is made of aluminum, for example. An electrode unit is disposed within the cell housing. The cell housing is, for example, prismatic (prism), in particular square, or is configured cylindrically. Other constructional shapes for cell housings are also known.
The two electrodes of the electrode unit are electrically connected to the poles (Polen) of the battery cells, which poles are also called terminals. The terminals of the battery cells can be mounted at the cell housing and electrically insulated from the cell housing. However, it is also conceivable for the cell housing to have a first housing part, which forms the negative terminal, and a second housing part, which forms the positive terminal, wherein the two housing parts are electrically insulated from one another.
A battery cell according to the preamble is known from DE 1020111076919 A1, which has an electrode unit that is arranged in a metallic housing. The housing comprises two housing parts, which are electrically insulated from one another by an insulating element. The anode and cathode of the electrode unit are electrically connected to each of the two housing pieces. The two housing parts thus form the terminals of the battery cells.
From KR20150028068, a battery cell is known, which has an electrode unit, which is arranged in a multi-part housing. The housing here comprises two side parts, on which a flat head part is placed.
In US 2012/0052365 A1 a lithium ion battery is disclosed, which has a housing and two or more battery cells arranged therein. The battery cells are connected together to a positive electrode collector (Kollektor) and a negative electrode collector.
Disclosure of Invention
A battery cell is proposed, comprising a cell housing in which an electrode unit is arranged. The electrode unit has an anode electrically connected to the negative electrode terminal and a cathode electrically connected to the positive electrode terminal. The cell housing has a first housing part and a second housing part. The first housing member forms the negative terminal, and the second housing member forms the positive terminal. In this case, an insulating element is provided, which electrically insulates the first housing part from the second housing part.
According to the invention, a negative connector element is arranged within the cell housing, which is electrically connected to the anode and to the first housing part, and a positive connector element is electrically connected to the cathode and to the second housing part. The negative connector element and the positive connector element are held in a positive manner in the insulating element.
According to an advantageous embodiment of the invention, the first housing part and the second housing part are also held in a form-fitting manner in the insulating element.
Preferably, the anode is connected in a material-tight manner to the negative connector element. The anode is thus electrically and mechanically connected to the negative connector element. Likewise, the cathode is preferably connected in a material-tight manner to the positive connector element. Thus, the cathode is electrically and mechanically connected to the positive connector element.
Preferably, the negative connector element is connected to the first housing part in a material-locking manner. The negative connector element is thus electrically and mechanically connected to the first housing part. Likewise, the positive connector element is preferably connected to the second housing part in a material-tight manner. The positive connector element is thus electrically and mechanically connected to the second housing part.
According to an advantageous variant of the invention, the insulating element electrically insulates the negative connector element from the cathode and/or the insulating element electrically insulates the positive connector element from the anode. Furthermore, the insulating element advantageously electrically insulates the negative connector element from the positive connector element.
A method for manufacturing a battery cell is also presented, said method comprising the steps mentioned below.
First, the first connector element is connected with the first electrode of the electrode unit. The first connector element can be a negative connector element or a positive connector element. The first electrode can be an anode or a cathode. Thus, alternatively, a negative connector element is connected to the anode, or a positive connector element is connected to the cathode.
Thereafter, the first connector element is inserted into the insulating element in such a way that the first connector element is held in a form-fitting manner in the insulating element.
The second connector element is then inserted into the insulating element in such a way that it is held in a form-fitting manner in the insulating element. When the first connector element is a negative connector element, then the second connector element is a positive connector element. When the first connector element is a positive connector element, then the second connector element is a negative connector element.
Thereafter, the second connector element is connected with a second electrode of the electrode unit. When the first electrode is an anode, then the second electrode is a cathode. When the first electrode is a cathode, then the second electrode is an anode.
Subsequently, the first and second housing parts are inserted into the insulating element in such a way that the housing parts form a cell housing, which encloses the electrode units, and in such a way that the insulating element electrically insulates the housing parts from one another.
Thereafter, the first connector element is connected with the first housing member and the second connector element is connected with the second housing member such that the first electrode is electrically connected with the first housing member and the second electrode is electrically connected with the second housing member.
The first housing member then forms a first terminal and the second housing member forms a second terminal. When the first electrode is an anode and the second electrode is a cathode, then the first terminal is a negative terminal and the second terminal is a positive terminal. When the first electrode is a cathode and the second electrode is an anode, then the first terminal is a positive terminal and the second terminal is a negative terminal.
Preferably, the first housing part and the second housing part are inserted in a form-fitting manner into the insulating element.
Preferably, the connector element is connected to the electrode in a material-tight manner, in particular by means of laser welding or ultrasonic welding.
Likewise, the connector element is preferably connected to the housing part in a material-tight manner, in particular by means of laser welding or ultrasonic welding.
The battery cell according to the invention is advantageously used in Electric Vehicles (EV), in hybrid vehicles (HEV), in plug-in hybrid vehicles (PHEV), in stationary batteries (in particular for grid stabilization in the home), in batteries in marine applications (for example in the case of shipbuilding or in the case of jet skis) or in batteries in aeronautical applications (in particular in the case of aircraft manufacturing). Other applications are also conceivable.
Advantages of the invention
In the battery cell according to the invention, the volume ratio present within the cell housing is used more effectively in connection with battery cells known from the prior art. In particular, space is saved, since the insulating element takes on a plurality of functions. In one aspect, the insulating element is used to electrically insulate the electrodes, the connector element, and the housing pieces of different polarities from each other. On the other hand, the insulating element is also used to positively receive and hold the connector element and the housing part. Furthermore, like conventional holders (retainers), the insulating element serves for positioning the electrode units within the cell housing. Advantageously, the number of components required is also reduced. The battery cell comprises only one electrode unit, two connector elements, two housing parts and one insulating element. Thereby, the battery cell also has a more robust design.
The production (in particular assembly) of the battery cells is also advantageously simplified by means of the method according to the invention. In particular, a relatively simple connection of the electrodes at the housing part of the battery cell, which is designed as a terminal, is achieved. In this case, the connector elements are welded to the housing parts by means of laser welding through the housing parts after the housing parts have been closed to form a cell housing.

Detailed Description
In the following description of embodiments of the invention, identical or similar elements are denoted by the same reference numerals, wherein in each case a repeated description of these elements is dispensed with. The figures only schematically illustrate the subject matter of the invention.
Fig. 1 shows a schematic cross-section of a battery cell 2. The battery cell 2 comprises a cell housing 3, which is embodied in an electrically conductive manner. The cell housing 3 has a first housing part 61 and a second housing part 62, which are electrically insulated from one another by a surrounding insulating element 80. The housing parts 61, 62 are made of metal, for example aluminum. The first case member 61 forms the negative terminal 11, and the second case member 62 forms the positive terminal 12. The voltage supplied by the battery cell 2 can be intercepted by the terminals 11, 12. The battery cell 2 can also be charged via the terminals 11, 12.
The electrode unit 10, which has two electrodes, namely an anode 21 and a cathode 22, is arranged within the cell housing 3 of the battery cell 2. Currently, the electrode unit 10 is configured as an electrode winding, and the anode 21 and the cathode 22 are respectively foil-implemented and wound into the electrode winding with the separator 18 interposed therebetween. It is also conceivable that the electrode unit 10 is configured as an electrode stack in which the layers of the anode 21 and the cathode 22 are stacked one above the other with the layers of the separator 18 interposed therebetween, respectively.
The arrester 31 of the anode 21 is embodied in an electrically conductive manner and is made of metal (e.g., copper). An anode contact ferrule (anonkontaktaffahnen) protrudes from the arrester 31 of the anode 21, which is electrically connected to the negative connector element 51. The negative connector element 51 is electrically connected to the first housing part 61. Thus, the anode 21 is electrically connected to the negative terminal 11 of the battery cell 2 through the negative connector element 51.
The arrester 32 of the cathode 22 is embodied in an electrically conductive manner and is made of metal (for example aluminum). A cathode contact ferrule extends from the arrester 32 of the cathode 22, which is electrically connected to the positive connector element 52. The positive connector element 52 is electrically connected to the second housing member 62. Thus, the cathode 22 is electrically connected to the positive terminal 12 of the battery cell 2 through the positive connector element 52.
Fig. 2 shows a perspective view of the insulating element 80. The insulating element 80 has a surrounding frame with an H-shaped cross section. The first receiving area 81 and the second receiving area 82 are formed at the end face of the insulating member 80. In the view shown here, only the first receiving area 81 is visible, which is used for receiving the negative connector element 51. The second receiving area 82 is covered in this view, which is used to receive the positive connector element 52. The insulating element 80 is currently produced from plastic by injection molding technology and is constructed rotationally symmetrical as well as mirror-symmetrical.
In part of fig. 3 a), 3 b) and 3 c), fig. 3 shows an assembly step for manufacturing the battery cell 2. The electrode unit 10 is provided in preparation for the method (Verfahrensvorbereitend). The cathode 22 and the anode 21 protrude from the electrode unit 10 side by side at end surfaces. Likewise, connector elements 51, 52, insulating elements 80 and housing parts 61, 62 are provided.
Part of fig. 3 a) shows the electrode unit 10, while the cathode 22 is connected to a positive connector element 52. The cathode contact collar of the cathode 22 is welded to the positive connector element 52, in particular by means of ultrasonic welding. Currently, the positive connector element 52 is made of aluminum and is implemented solid. Thereby, the positive connector element 52 is able to discharge the heat generated during the welding operationAnd then transmits the force acting on the cell housing 3 so as to protect the battery cells 2.
The positive connector element 52 is then inserted into the second receiving area 82 of the insulating element 80. Thereby, the positive connector element 52 is held in a positive fit in the insulating element 80. The electrode unit 10 is also received in the insulating member 80. Part of fig. 3 b) shows the state after insertion of the positive connector element 52 into the second receiving area 82.
Subsequently, the negative connector element 51 is inserted into the first receiving area 81 of the insulating element 80. Thereby, the negative connector element 51 is also held in a form-fitting manner in the insulating element 80. Part of fig. 3 c) shows the state after insertion of the negative connector element 51 into the first receiving area 81.
Thereafter, the anode contact ferrule of the anode 21 is connected to the negative connector element 51 by means of welding, in particular by means of ultrasonic welding. Currently, the negative connector element 51 is made of copper and is implemented solid. Thereby, the negative connector element 51 can discharge heat generated during the welding operationAnd then transmits the force acting on the cell housing 3 so as to protect the battery cells 2.
Subsequently, the first housing piece 61 and the second housing piece 62 are inserted into the insulating member 80 from opposite sides. The housing parts 61, 62 are held in a form-fitting manner in the insulating element 80. The housing parts 61, 62 then form a cell housing 3, which encloses the electrode unit 10. The insulating element 80 electrically insulates the housing parts 61, 62 from each other.
Thereafter, the negative connector element 51 is connected with the first housing part 61 and the positive connector element 52 is connected with the second housing part 62. The connector elements 51, 52 are welded to the housing parts 61, 62 from the outside (i.e. through the housing parts 61, 62) by means of laser welding.
Fig. 4 shows a perspective view of the battery cell 2 thus manufactured. The anode 21 of the electrode unit 10 is electrically connected to the first housing part 61, said anode forming the negative terminal 11 of the battery cell 2. The cathode 22 of the electrode unit 10, which forms the positive terminal 12 of the battery cell 2, is electrically connected to the second housing part 62.
Fig. 5 shows a cross-sectional view of the battery cell 2 from fig. 4. As already mentioned, the insulating element 80 has an H-shaped cross section in which the housing parts 61, 62 are positively received. The insulating element 80 electrically insulates the housing parts 61, 62 from one another.
The negative connector element 51 is held in a positive manner in a first receiving area 81 of the insulating element 80, and the positive connector element 52 is held in a positive manner in a second receiving area 82 of the insulating element 80. The insulating element 80 electrically insulates the negative connector element 51 from the cathode 22. The insulating element 80 also electrically insulates the positive connector element 52 from the anode 21.
The present invention is not limited to the embodiments described herein and the aspects highlighted therein. Rather, within the scope of the description, a plurality of variants are possible, which are within the framework of the process of the skilled person.
