Abstract
An article adapted to receive multiple battery cells, such as a battery module, which provides thermal insulation between adjacent battery cells using thermally insulating layers comprising a ceramifiable elastomeric silicone material, using fumed silica (amorphous SiO2) or fumed silica (amorphous SiO2)+quartz (crystalline SiO2). There is also provided, the use of said ceramifiable elastomeric silicone material as a means of delaying and/or preventing thermal runaway in such an article. Typically, the battery cells for which this article is designed are lithium-ion battery cells.
