Problems solved by technology

[0004] However, it is disadvantageous that during the welding process heat is introduced into the interior of the monocoque, which can damage or destroy components arranged in the monocoque, such as the electrode stack
Measures for protecting temperature-sensitive components are therefore required, which lead to increased material expenditure, time-consuming and thus increased costs

Embodiment Construction

[0028] Corresponding parts have the same reference numerals in all figures.

[0029] figure 1 A monoblock 1 designed as a frame flat monolith is shown in the opened state.

[0030] The cell 1 comprises an electrode stack 2 arranged in a cell housing, wherein the cell housing has two electrically conductive housing side walls 3 , in particular planar sides, and a An electrically insulating frame 4 surrounding the edges.

[0031] In this case, the electrode stack 2 is in particular formed by membrane electrodes (not shown in detail), wherein in the central region of the electrode stack 2 membrane electrodes of different polarity, in particular aluminum and / or copper foils and / or made of metal The alloy films are stacked on top of each other and are electrically insulated from one another by means of separators, not shown in detail, in particular separator films.

[0032] Membrane electrodes of the same polarity are electrically connected to one another and form pole contacts ...

Abstract

The invention relates to a method for producing an individual cell (1) for a battery, comprising an electrode stack (2) disposed inside a cell case, said cell case being defined by two electroconductive lateral walls (3) and an interposed, peripheral, electrically insulating frame (4), current lugs (2.1) of one polarity being combined to give respective pole contacts (P) of the electrode stack (2) and an electroconductive connection being produced between the pole contacts (P) and the lateral walls (3). The electroconductive connection is produced in the open state of the individual cell (1).

Description

technical field [0001] The invention relates to a method for producing battery cells according to the preamble of claim 1 . Background technique [0002] According to the prior art, high-voltage batteries, such as lithium-ion batteries, are known for vehicle applications, said batteries being in particular composed of a plurality of cells electrically connected in series and / or in parallel. In this case, in a bipolar cell, the electrical contacts, ie the positive and negative poles, are situated directly on parts of the housing that are electrically insulated from one another. [0003] From P810600 (official document registration number 102007063181.4) a cell, in particular a flat cell, is known for a battery, which has an electrode stack / group of electrodes arranged in the cell housing. The one-piece housing has two opposite housing side walls and an electrically insulating frame arranged between the two housing side walls. The electrical contacting of the electrode stack...
