Pack lithium batteries need to use silicone

Which silicone products are suitable for sealing and gasketing battery packs?

At Elkem, we supply four main classes of silicone products for sealing and gasketing battery packs in H&EVs: CAF™ 24 MF is a one-part (RTV-1) formulation that is suitable for both FIPG and CIPG processing. It is able to adhere to a wide variety of substrates, with particular strength for metal surfaces.

What makes a good battery pack?

Structural adhesives, sealants, and thermally conductive materials are helping to build better battery packs. Electric vehicles (EV) have been around for more than 120 years.

What is a battery pack?

Battery packs were often created from whatever battery configurations were commercially available, including cylindrical, prismatic, and pouch cells. Now, as EVs are becoming more popular, the development of bespoke lithium-ion battery cells has allowed better performance at an ever-improving price point.

Why is silicone a good choice for h&ev battery sealing?

Long lifespan – Silicones have a long lifetime in H&EV battery sealing applications, because of their chemical inertness and high resistance to oxidation and UV radiation.

What is a complex battery pack?

Complex battery pack designs contain epoxy or silicone potting/encapsulation systems with excellent adhesion flexibility, thermal cycle/shock resistance, low stress and outstanding electrical stability. Transformative breakthroughs in battery technology is a daunting task.

Are silicone gaskets a good choice for h&ev battery packs?

Silicones are a high-performance option for producing both form-in-place and cure-in-place gaskets for H&EV battery packs, and at Elkem we’ve got the product range and application expertise that will help you make the perfect choice. Battery performance and cost is widely recognized as a limiting factor in the uptake of H&EVs.
