Electrification & on-board electronics

As an alloy of iron and silicon, electrical steel (also known as silicon steel) has unique magnetic properties, which make it of rapidly increasing importance in the energy-generation sector. Our steel specialists understand the technical specifications you need to meet, and are the world leaders in developing high-purity ferrosilicon (FeSi) alloys for premium electrical steels.

Various compounds of silicon are currently used to achieve silicon of different morphologies for use as anodes in lithium-ion batteries, in order to achieve higher loadings of lithium than is possible with graphite. However, the ideal solution varies according to the battery technology and application, and at Elkem we’re ready to help you identify the optimum silicon material for your anodes.

In the automotive industry, potting and sealing of electronics using silicones is used to ensure product integrity, and typically employs a two-part system to achieve a fully cured silicone coating. The resulting silicone-encapsulated product is highly reliable and resistant to environmental and vibration-induced damage.

Silicone rubbers are ideal for protecting battery and cabling systems in all classes of automobiles. They have the high thermal resistance needed in vehicles powered by internal combustion engines and hybrid vehicles, while also being sufficiently lightweight and flexible for use in electric vehicles.

The use of silicon as an alloying element enhances the mechanical properties of aluminium, ensuring greater structural integrity in lightweight vehicle designs. We supply nearly all the grades of metallurgical silicon you’re likely to need, and are ready to listen to your requirements.

Battery sealing is a critical aspect of H&EV design, aimed at maintaining battery integrity, eliminating safety risks, and maximizing product lifespan. Silicones emerge as a high-performance choice for creating both formed-in-place gaskets (FIPG) and cured-in-place gaskets (CIPG) in H&EV battery packs. These gaskets protect against moisture, dust, and potential fire hazards.

In the battery packs of hybrid and electric vehicles (H&EVs), thermal management materials help maintain an optimum temperature across the battery pack, as well as reduce fire risk. Silicones, with their high thermal stability and fire-retardant properties, are the favored materials for achieving these aims, and at Elkem we offer a range of high-purity silicones for thermal insulation, heat dissipation and fire protection.
