Electrochemical energy storage cell with metallic housing, process for producing an electrochemical energy storage cell with metallic housing

摘要

An inventive electrochemical energy storage device, hereinafter referred to as a secondary cell, has an electrode assembly. The electrode assembly has at least one separator and two electrodes of different polarity. The separator is arranged between two electrodes. The electrode assembly is provided to provide at least temporary electrical energy. Furthermore, the secondary cell has one, two or more current conductors. A current collector is provided, in particular to be electrically conductively connected to the electrode assembly, preferably with one of the electrodes, preferably by means of a material connection, particularly preferably by means of a welded connection. Furthermore, the secondary cell has at least two, in particular, metallic housing moldings. The housing moldings are provided to limit the electrode assembly from the environment of the secondary cell. The housing moldings are also provided with one another for the in particular positive and / or material-locking connection, wherein preferably the connected housing moldings form a housing around the electrode assembly. At least one, preferably two current conductors are in particular positively and / or materially connected to a housing molding, in particular with the same housing molding. At least one of the housing molded parts is provided to receive the electrode assembly in particular form-fitting and / or non-positively, and to clamp the electrode assembly preferably.
