Abstract: An energy storage device with at least one battery cell and a cooling device for cooling the at least one battery cell. The battery cell has a first side, which is facing a first side of the cooling device, and a releasable degassing opening arranged on the first side, wherein the energy storage device has a thermal interface material, which is arranged between the first side the battery cell and the first side of the cooling device. The energy storage device has at least one degassing channel, into which a gas emerging from the releasable degassing opening can be introduced. A flow path from the releasable degassing opening to the at least one degassing channel is sealed off from an area surrounding the at least one battery cell by a seal, which is provided by the thermal interface material.

Abstract: A method for assembling a battery, wherein the battery has a plurality of battery modules each including multiple battery cells, a battery housing at least partially enclosing the battery modules, and a temperature control unit thermally contacted with the battery housing. A thermally conductive cavity filling compound for thermally contacting the battery cells of the respective battery module with the temperature control unit is arranged in a cavity between an outside of a respective battery module inserted into the battery housing and an inside of the battery housing facing toward the outside of the respective battery module.

Abstract: A distribution device for distributing a cavity-filling compound in a cavity between at least one outer side of at least one battery module of a battery and an inner side, facing the at least one outer side of the respective battery module of the battery, of a battery housing at least partially enclosing the respective battery module. At least one injection nozzle and a vacuum-generation device, wherein the at least one injection nozzle is designed to inject the cavity-filling compound into the cavity, and wherein the vacuum-generation device is designed to generate a vacuum in an interior of the sealed battery housing, said interior including the cavity, and to draw the injected cavity-filling compound into the cavity and to distribute it by the vacuum.
