Silicon for Batteries

Silgrain® e-Si: The silicon of choice for the next generation of rechargeable lithium-ion batteries

Silgrain® e-Si is a collection of different silicon qualities tailored for manufacturing of silicon-based anodes for rechargeable lithium-ion batteries. The e-Si qualities are specialised to fit into different processes and technologies, normally developed in close cooperation with customers/partners.

The material can be tailored when it comes to chemical composition and sizing. The material is produced at our plant in Bremanger, Norway, where hydropower results in a lower carbon footprint on Elkem's materials compared to similar products.
