摘要： 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.

摘要： A multi-layer protective element for thermal insulation of a battery, a battery with such a protective element and the use of such a protective element are proposed. The protective element comprises a foam layer, a compressible fibre layer in the form of a sewn non-woven needled fibre fleece, and preferably one or two protective layers containing mica. This allows high compressibility as well as good insulation properties.

摘要： 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.
