NOVELTY - The flat battery cell (1) comprises a jacket for receiving an electric cell, and a current conductor (3) having a base section (4) and two contact sections (5), which are angled in relation to the base section around a bending axis (K) that is arranged parallel to a module direction (M) of the battery cell. The contact section is angled in rectangular to the base section. The current conductor has L-form where a shank is formed by the base section and a further shank is formed by the contact section, and U-form, which is formed by the base section and contact section.    USE - Flat battery cell useful in a battery arrangement (claimed) and as a secondary battery cell and rechargeable battery cell for electrically-driven vehicles.    ADVANTAGE - The flat battery cell can be simply and efficiently designed with less material consumption, improved fatigue strength and light-weight without the need of additional components.    DETAILED DESCRIPTION - The flat battery cell (1) comprises a jacket for receiving an electric cell, and a current conductor (3) having a base section (4) and two contact sections (5), which are angled in relation to the base section around a bending axis (K) that is arranged parallel to a module direction (M) of the battery cell. The contact section is angled in rectangular to the base section. The current conductor has L-form where a shank is formed by the base section and a further shank is formed by the contact section, and U-form, which is formed by the base section and contact section laterally arranged on it. The contact section extends away from the base section in a direction, which runs vertical to a larger side surface of the battery cell. The contact section is arranged parallel to the base section. A connecting web is arranged vertical to the base section and/or vertical to the contact section. The contact section is distanced from the base section at a length, which corresponds to a distance of the base section to a side surface of the battery cell running parallel to the base section. The contact section has a saw-tooth structure. The base section has a first passage hole. The base section has two alignment holes. A space holder is arranged between the base section and the contact section. A width of the space holder corresponds to a length of a web section of the current conductor. An INDEPENDENT CLAIM is included for a process for manufacturing a battery arrangement.
