BATTERY CELL WITH AN ELECTRODE ARRESTER INSULATION

The invention discloses a battery cell (1) which comprises a layer stack (2) having a plurality of anode layers (An) and a corresponding plurality of cathode layers (K), wherein the anode layers (An) and the cathode layers (K) are alternately stacked upon one another, and wherein a separator layer (S) is arranged between each anode layer (An) and each cathode layer (K), and wherein at least at a first end face (F1) of the layer stack (2) anode and/or cathode lead-out strips (4a, 4k) of at least some of the anode layers (An) and/or some of the cathode layers (K) are conducted laterally out of the layer stack (2). The battery cell (1) further comprises a housing (26) which encloses the layer stack (2) with the anode and/or cathode lead-out strips (4a, 4k), and which has at least at the first end face (F1) of the layer stack (2) a first cover (8) with an inside-mounted anode current collector (12a) or an inside-mounted cathode current collector, wherein the anode lead-out strips (4a) or the cathode lead-out strips (4k) are each brought together in a bundle-like manner, and are each contacted at the anode current collector (12a) or at the cathode current collector, as well as at least two insulating layers (IL) which are each fastened with a first end (E1) at the top side (Fo) or the bottom side (Fu) of the layer stack (2), wherein the insulating layers (IL) project beyond the layer stack (2) and their free, second ends (E2) are each aligned toward one another while forming folds (24) extending toward each other, such that the bundles (6a) of the anode lead-out strips (4a) or the cathode lead-out strips are each passed through between the two folds (24), and wherein the insulating layers (IL) are held in position by a spring action of their respective folds (24) against a pressure which is exerted indirectly by the first cover (8).
