Aerogel battery thermal barrier

Kistler ® aerogel battery thermal barriers are made with the core materials of preoxidized fiber or other types of aerogel composite materials, and have a polymer (PET, PI) film or flame retardant coating as the packaging material. After hot pressing or coating, they have excellent thermal insulation, fireproofing, and cushioning functions. These barriers are mainly used for thermal protection between the lithium battery cells, which can effectively prevent thermal runaway in the cells, and greatly improves the driving safety of new energy vehicles. In case of any thermal runaway in one of the electric cells, the aerogel thermal barrier between the cells can block the heat transfer to the adjacent cells and prevent heat diffusion, thus avoiding the domino effect of thermal runaway in the electric cells of new energy power batteries.

Fireproof insulation composite tape

This product can be used outside the power battery module to solve the problem of providing high temperature electrical thermal insulation protection for the battery.

Aerogel fireproof coating

Kistler ® intumescent aerogel fireproof coating is a double-component, solvent-free epoxy fireproof coating, which is applied to the surface of the substrate. The coating will expand and sponge when exposed to fire, and then carbonize instantly to form a thermally insulating refractory layer, delaying the heating speed of the substrate, and thereby improving its fire resistance. 0.6 mm-thick Kistler ® intumescent fireproof coating can expand 20 times when exposed to fires burning at 1000℃, and the back surface temperature won’t exceed 200℃ within 5 minutes. This coating can be widely applied to metal surfaces, including the battery packs of new energy vehicles, and it has a robust fireproofing and thermal insulation effect.

Aerogel sponge

Kistler® aerogel sponge is a new style flexible aerogel thermal insulation material compsite with soft foam, which solves the problem of thermally insulating electronic products or battery packs in narrow spaces, and provides high-grade thermal protection for electronic components or battery chips, thus improving the safety performance and service life of products, while also improving the comfort of electronic products for human use. It is very suitable for the application in the consumer electronics industry, as well as in vehicular electronics, battery packs, and other products.

Aerogel fireproof blanket

The Kistler® aerogel fireproof blanket is made with aerogel as the fireproof thermal insulation layer and glass fiber cloth as the surface material. The product has the characteristics of being fireproof, incombustible, with high thermal insulation, strong hydrophobicity, and other advantages. It can be used for the thermal insulation of new energy battery boxes, engine compartments, body floors, and other parts. This product is the standard configuration for electric buses, and it meets the requirements of 4.3.2 Fire retardant and thermal insulation performance of the GB38032-2020 Electric Bus Safety Requirements. It can effectively block the spread of fire caused by battery thermal runaway and extend the escape time for passengers.
