Title:
ELASTOMERIC SILICONE MATERIALS AND THEIR APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/163827
Kind Code:
A1
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 SiO 2) or fumed silica (amorphous SiO 2) + quartz (crystalline SiO 2). 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.
