BATTERY WITH A STACK OF BIPOLAR INDIVIDUAL BATTERY CELLS

摘要

A battery has a stack (14) of bipolar individual battery cells (1). Each individual battery cell (1) comprises one electrode stack (5) and two enveloping sheet metals (3, 4) which limit the individual battery cell (1) at least in a stacking direction. The electrode stack (5) is connected to at least one of the enveloping sheet metals (3, 4) by at least one weld. According to the invention, in the area of at least one weld (10) the enveloping sheet metal (3, 4) welded to the electrode stack (5) and/or the enveloping sheet metal (4, 3) resting against this enveloping sheet metal (3, 4) is implemented recessed to the adjacent individual battery cell (1). Thereby the enveloping sheet metals (3, 4) of the adjacent individual battery cells (1) do not make contact in the region of at least one weld (10).
