Abstract

The invention relates to a traction battery for an electrically or partially electrically powered motor vehicle and to a motor vehicle with such a traction battery. The traction battery comprises a battery cell stack, wherein the battery cell stack comprises several battery cells, wherein the battery cells are arranged side by side in a stacking direction (X), wherein a compensation element (30) is arranged between two battery cells adjacent in the stacking direction (X), wherein the compensation element (30) is configured to compensate for a change in the volume of the battery cells, wherein the compensation element (30) has a first wall element (31) on its side facing one battery cell and a second wall element (32) on its side facing the other battery cell, wherein the compensation element (30) has a cavity (40) fluid-tightly enclosed by the first and the second wall elements (31, 32).wherein the cavity (40) accommodates a gas-filled gas cushion, wherein at least one of the wall elements (31, 32) is provided on its inner side facing the cavity (40) and / or on its outer side facing away from the cavity (40) with a coating (70) of an intumescent material.
