Embodiment Construction

[0024] figure 1 A hybrid battery assembly 10 according to the invention is shown, which has a plastic housing 12 open on both sides and two covers 14 , 16 made of metallic material. Here, the first cover 14 covers the first opening 18 of the plastic housing 12 in a fluid-tight manner, and the second cover 16 covers the second opening 20 of the plastic housing 12 in a fluid-tight manner, so that a closed interior space 22. The inner space is filled with an electrolyte solution. In the embodiment shown, the plastic housing 12 is designed as a rectangular frame. Preferably, the plastic housing 12 is an injection molded part, in particular made of polypropylene.

[0025] Covers 14, 16 are secured to plastic housing 12, for example by mechanical attachment. However, other possibilities are also conceivable for fastening the covers 14 , 16 on the plastic housing, for example by gluing or additional fastening elements.

[0026] The caps 14 , 16 can be made of aluminum, wherein t...

Abstract

A hybrid battery component (10) is specified, having a plastic housing (12) filled with an electrolyte solution and open on both sides, an electrode stack (24) arranged in the plastic housing (12) andhaving at least one cathode (28) and at least one anode (26), and two covers (14, 16) made of a metallic material, wherein a first cover (14) completely covers a first opening (18) and a second cover(16) completely covers a second opening (20) of the plastic housing (12) in a fluid-tight manner, and wherein the at least one anode (26) is electrically conductively connected to the first cover (14) by means of a first contact element (30) and the at least one cathode (28) is electrically conductively connected to the second cover (16) by means of a second contact element (32). A method for producing a hybrid battery component (10) is also specified.

Description

technical field [0001] The invention relates to a hybrid battery component and a method for producing a hybrid battery component. Background technique [0002] Hybrid battery components, such as lithium-ion cells, are currently produced as pouch cells, prismatic cells or circular cells. In pouch cells, the electrodes are welded into the plastic film. Prismatic cells have a metallic, rectangular housing and circular cells have a metallic, cylindrical housing. [0003] Pouch cells and cylindrical cells have the disadvantage that elements that increase the safety of the cell can hardly be integrated into the corresponding housing. In the case of prismatic battery cells, such safety elements can be integrated relatively easily in the housing, however, prismatic battery cells are expensive to manufacture. Contents of the invention [0004] It is therefore the object of the present invention to provide a hybrid battery assembly with high battery safety which is advantageous w...
