In an apparatus for adjusting a phase position of a camshaft in relation to a crankshaft which drives the camshaft, including an electric actuator for operating an adjustment mechanism, which can move the camshaft to a basic or emergency-operating position in the event of a shut-down as a result of an operational fault, the emergency-operating position can be reliably reached with the aid of the electric actuator which is supplied with energy by an energy supply that is separate from an operational energy supply and which is capable of moving the adjustment mechanism to the emergency-operating position. Also, a method for operating an apparatus for adjusting a phase position of a camshaft is provided.

A battery includes a number of single cells interconnected in series and/or in parallel, the electrical poles of which for the electrical interconnection are connected to one another in a positive-fit and/or integrally bonded manner, directly or by means of cell connectors. The battery also includes a battery monitoring unit connected to the electrical poles and/or to the cell connectors in a positive-fit and/or integrally bonded manner. The electrical poles of the single cells, the cell connectors, and/or the battery monitoring unit have redundant contact areas for the positive-fit and/or integrally bonded connection. In each case only one of the contact areas which are redundant with one another is connected in a positive-fit and/or integrally bonded manner, and the further contact area(s) is/are not connected.

A single cell for a battery includes an electrode stack situated within a cell housing formed from two electrically conductive shell-shaped housing side walls situated essentially in parallel opposite one another, having a shell flange extending around the edges. The shell flanges are joined to one another to form a flange area and are electrically insulated from one another. Pole contact tabs of the electrode stack are connected electrically connected to the housing side walls. At least one of the housing side walls has a section protruding, at least in parts, beyond the flange area of at least one housing edge of the cell housing. The protruding section of the housing side wall is angled in the direction of a cell interior and in the direction of a shell base of the housing side wall, and in the angled state protrudes beyond the shell base by a predetermined amount.
