METHOD FOR PRODUCING A CELL HOUSING FOR A BATTERY CELL AND CELL HOUSING

The invention relates to a method for producing a cell housing for a battery cell, comprising the following steps: (i) mechanically deforming a plate-shaped base body, in particular made of aluminum or steel, into a hollow body, the hollow body having a base and a wall, the wall extending at an angle to the base; an opening of the hollow body is formed opposite the bottom, and a connecting region is formed between the bottom and the wall by means of the angle; (ii) selectively supplying thermal energy having a predetermined temperature to the connection region, at least one further region of the hollow body remaining not treated by thermal energy, the predetermined temperature having at least one value, and the thermal energy having at least one value; in this way, the volume of the particles is increased by selectively supplying thermal energy, i.e. The volume of the particles of the material structure of the connecting region. 本发明涉及一种用于制造用于电池单体的单体壳体的方法，该方法具有如下步骤：(i)将板形的、尤其是具有铝或钢的基体机械地变形成型为空心体，其中，所述空心体具有底部和壁
