Abstract
A battery includes at least two battery cells arranged adjacent to one another and each arranged in a battery cell housing. Each battery cell has at least one battery cell terminal. The battery also includes one degasification element per battery cell. Each degasification element is arranged within the battery cell housing associated with the respective battery cell and is configured to discharge gases generated within the respective battery cell from the respective battery cell in the presence of a predetermined gas pressure. The battery also includes a cover configured to cover at least a part of the surfaces of the battery cells and cover the degasification elements of the battery cells in air-tight fashion. The cover has, in each case in a region of the degasification elements, predetermined breaking points assigned to the degasification elements.
