Abstract: A multilayer protective element for thermal and electrical insulation of a battery, a battery having such a protective element, and the use of the protective element for preventing flame or spark leakage from a battery are proposed. The protective element has a carrier layer of a silicate fabric and a protective layer of phlogopite.

Abstract: A multi-layer heat insulation element for thermal insulation of a battery is proposed, with a first cover layer, with a second cover layer and with a compressible and/or pliable intermediate ply arranged between the cover layers, which has at least one heat-resistant fibre layer, wherein the fibre layer is formed from a needled nonwoven and/or wherein the cover layers are flexurally weak and the heat insulation element as a whole is compressible and flexibly pliable.

Abstract: A multi-layer protection element for thermal insulation of a battery, a battery with such a protection element and the use of the protection element to filter gases escaping in case of fire and to prevent the escape of flames and/or sparks are proposed. The highly gas-permeable protection element comprises a carrier layer of a fabric and a compressible fibre layer in the form of a sewn non-woven fabric. The protection element is arranged between at least one battery cell and a housing wall of the battery and covers an outlet of the housing wall on the inside. This enables good pressure compensation in the event of fire and/or a short circuit, wherein escaping gases are filtered in particular through the fibre layer and the escape of flames or sparks through the outlet is prevented.
