Abstract:
The invention relates to an individual battery cell (1) in the form of a bipolar flat-cell frame comprising two enveloping sheets (4, 5) at least one of which has at least one bent cooling lug (11) on at least one lateral edge. The invention is characterized in that the bent cooling lug (11) of at least one enveloping sheet (4, 5) comprises at least one meander-shaped portion (13).
Abstract:
The invention relates to an individual cell (1) for a battery, comprising an electrode stack (7) arranged in a cell housing, said cell housing being formed from two electrically conductive substantially parallel opposing shell-like housing side walls (2, 3), each with a peripheral shell flange (5) on its rim, the shell flanges (5) being materially bonded and electrically insulated against each other to form a flange region (12), terminal contact lugs (11) on the electrode stack (7) being electrically connected to the housing side walls (2, 3). According to the invention, at least one of the housing side walls (2, 3) protrudes at least partially beyond the flange region (12) along at least one edge of the cell housing, the portion (13) of the housing side wall (2, 3) that protrudes beyond the flange region (12) being angled towards the interior of the cell (9) and towards a shell base part (10) of the housing side wall (2, 3) and at least one fastening element (16) being formed in or on at least one angled portion (13). The invention further relates to a battery which is constituted of a plurality of individual cells (1).
Abstract:
The invention relates to an individual cell (1) for a battery, comprising at least one cell housing in which an electrode foil arrangement (2) is arranged. According to the invention, the front ends of electrode foils of a first polarity are connected in an electrically conductive manner to a first housing part (5) and the front ends of electrode foils of a second polarity are connected in an electrically conductive manner to a second housing part (6), the regions in which they are connected to the housing parts (5, 6) lying opposite.
