Embodiment Construction

[0078] The housing indicated by 100 as a whole is in Figure 1 to Figure 3 The conventional embodiment shown in is, for example, a component of an electrochemical cell 102 , such as a cell of a lithium-ion battery.

[0079] The housing 100 serves to accommodate electrochemical elements 104 of an electrochemical cell 102 .

[0080] The electrochemical element 104 is designed in particular as a battery core 106 .

[0081] In the installed state of the electrochemical cell 102 , the battery core 106 is accommodated in the interior space 108 of the housing 100 and is in electrical contact with the cell terminal 112 arranged on the outside of the housing 100 by means of the battery core connector 110 . connected in a connected manner.

[0082] The cell terminal 112 forms a pole 114 of the electrochemical cell 102 .

[0083] especially from figure 1 and figure 2 (which shows the electrochemical cell 102 before the electrochemical cell is completed), two housing components 116 ...

Abstract

In order to provide a reliably leak-proof and easily producible housing for an electrochemical cell, it is proposed that the housing comprises the following parts: At least two housing components, in particular by means of a welded connection and / or At least two housing components are connected or connectable to each other.

Description

technical field [0001] The invention relates to a housing for an electrochemical cell (Zelle) and to a method for producing such a housing. Background technique [0002] Housings for electrochemical cells can be, for example, housings for lithium-ion batteries. Such housings must preferably be closed in a gas-tight manner and remain sealed even at high pressures, for example approximately 10 bar. For this purpose, such a housing is produced, for example, from a metallic material, wherein a plurality of housing parts (housing components) are connected to one another by means of laser welding. [0003] The housing can be formed, for example, from two housing parts, in particular a cup and a cover matched thereto. For a reliable sealing of the housing and a sufficient stability of the housing, a secure positioning of the cover on the cup must preferably be ensured here. This can be achieved in particular by using different joint geometries. [0004] The housing component is...
