Particle Separator for Battery Packs and Battery Back Having a Particle Separator

A particle separator includes an inlet and an outlet where solid particle are separable from a particle-battery gas mixture introduced with overpressure at the inlet by the particle separator and where the battery gas is depressurizable at the outlet. The particle separator further includes a gas channel wound in a screw shape in an axial direction which fluidically connects the inlet to the outlet. The gas channel has a particle emission on an outlet-side end of the particle separator which is opened in a radial direction and through which the solid particles are passable.
