Battery cell and a battery block for

The invention relates to a cell block (1) for a battery (2), in series and / or parallel electrically of interconnected with a plurality of electrochemical individual cells (3), which are formed as flat cells in the cell block (1) aligned substantially parallel to one another and behind one another are arranged and are clamped together by means of at least one clamping element. According to the invention the tensioning element as a temperature-controlling (4) for controlling the temperature of the individual cells (3) is formed, which are arranged on one longitudinal side of the cell block (1) and is thermally coupled to the individual cells (3). Furthermore, the invention relates to a battery (2).
