Pouch cell with deflectors

The flat battery cell comprises alternately stacked anode foils (1) and cathode foils (2), which are separated from each other by separator foils (3) and are arranged in a foil housing (4). The anode foils comprise multiple layers and the cathode foils comprise multiple layers, which are connected with arresters (11,12) that form poles (9,13) of the flat battery cell. The arrester of the cathode foils is made of aluminum and carries an aluminum oxide layer. The arrester has a coating (18), which is made of nickel, tin or silver.
