Ferroglobe: NEW MATERIALS FOR THE ENERGY TRANSITION

Ferroglobe is committed to developing next-generation materials that accelerate the deployment of energy‑transition technologies, with silicon playing a central role in enabling renewable energy, energy storage, and sustainable mobility.

In 2024, Ferroglobe signed a Memorandum of Understanding with U.S.-based Coreshell to develop the first metallurgical‑grade silicon suitable for use in electric‑vehicle batteries. This partnership aims to deliver a breakthrough material capable of replacing graphite and silane‑based compounds, reducing costs while significantly improving the performance of lithium‑ion batteries.

This development is powered by three complementary, high-impact approaches:

• Coreshell’s patented nanocoating, which stabilizes micrometric silicon particles and prevents degradation, making silicon truly viable as an anode material.
• Ferroglobe’s advanced metallurgical purification process, capable of producing silicon with up to 99.995% purity, without chemical reagents and at highly competitive costs.
• External Collaboration for Research, Development and Innovation

The strategic impact of this project is substantial: silicon can store up to 10 times more energy than graphite, enabling electric vehicles to achieve up to 30% greater driving range. Through this partnership, Ferroglobe positions itself at the forefront of the global race to industrialize silicon-based batteries.
