Abstract: Addition curing electrically conductive liquid silicone rubber (LSR) compositions, their methods of preparation, and cured elastomeric products made from the compositions are provided. The compositions are cured to form elastomeric products suitable for high voltage applications such as cable joints, cable terminal applications, cable accessories and connectors. In general, the composition comprises: (a) at least one polydiorganosiloxane having at least two alkenyl groups per molecule: (b) at least one organohydrogenpolysiloxane: (c) at least one reinforcing filler: (d) at least one hydrosilylation catalyst: and (e) an electrically conductive filler. Component (e) comprises: (i) extra conductive carbon black: and (ii) single walled carbon nanotubes.

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.
