Abstract

A cell module for a battery of a motor vehicle has a plurality of battery cells for storing electrical energy and a module frame which includes at least two pressure elements, between which the battery cells are arranged, and at least one tension rod which is loaded in tension. The tension rod is formed from a material and by which the pressure elements are clamped against each other via the battery cells. As a result, the battery cells are compressed, wherein the pressure plates are clamped against each other by the tension rod in such a manner that a yield strength or the 0.2% yield limit of the material of the tension rod is reached.
