Battery having a cell assembly

In a battery having a cell assembly (Z) comprising a plurality of series and / or parallel-connected single cells with each other (1), is arranged at least one cooling plate (5) on the pole side of the single cells (1). In this case, output lugs (4, 13, 14) of electric poles of the individual cells (1) thermally connected to the cooling plate (5) coupled. At least one of the output lugs (4, 14) is such sections angled such that at least a first portion (4.2, 14.2) of the conductor lug (4, 14) to the cooling plate parallel (5). According to the invention the individual cells (1) in the frame members (6) are arranged, which are by means of first clamping elements (7) in such a positive manner compressible that the output lugs (4, 13, 14) of adjacent individual cells (1) are electrically interconnected.
