1. A heat shield (1) suitable for batteries or battery arrangements (2),
wherein the heat shield (1) has a layer structure made of a first layer (4) based on a temperature-resistant elastomer for impact absorption, a second layer (5) made of a material that is resistant to high temperatures as heat protection, a layer (6) having intumescent properties for creation of a thermal insulation, a carrier plate (7), and a heat-distributing layer (8) between the second layer (5) and the layer (6) with intumescent properties.
