Insights
Ferroglobe's strategic investment in Coreshell represents a significant vertical integration play that could substantially expand its addressable market. As an anchor investor in this
The partnership creates a potentially lucrative new revenue stream for Ferroglobe, whose metallurgical silicon production capabilities can now be directed toward high-margin battery applications rather than solely traditional industrial uses. Most critically, this positions GSM to potentially capture value from the cost advantage Coreshell claims - with metallurgical silicon reportedly being half the cost of graphite while delivering 30-40% higher energy density.
From a supply chain perspective, this aligns perfectly with current market trends toward resource nationalism and domestic production. With graphite heavily dominated by Chinese producers, Ferroglobe's domestically-sourced silicon offers both strategic and regulatory advantages for US and European manufacturers.
While commercial validation with automakers remains pending, the partnership fundamentally transforms Ferroglobe's long-term growth trajectory by establishing it as a key supplier in the EV battery value chain rather than just a commodity producer. The 2025 timeline for automaker samples suggests revenue impact could begin materializing within 12-18 months.
This partnership solves critical manufacturing and scaling challenges that have hampered silicon anode commercialization for years. Ferroglobe's involvement is particularly significant as it addresses the most fundamental barrier: raw material costs and processing complexity.
What makes this development technically compelling is that Coreshell's innovation appears to use unrefined metallurgical silicon - not the highly processed, nano-structured silicon that has required complex and expensive manufacturing processes in previous attempts. This represents a substantial manufacturing simplification that could enable rapid scaling while maintaining Ferroglobe's existing production methods.
The article's mention that Coreshell uses standard equipment from TopMaterial further validates the scalability thesis. Without requiring specialized infrastructure, deployment velocity can accelerate dramatically compared to competing technologies that demand custom manufacturing lines.
The 475+ cycles at 90% capacity retention reported in testing, with expectations of 1000+ cycles in production cells, suggests the silicon expansion/contraction challenges that previously cycle life may have been overcome. Similarly, the 15-minute charging capability demonstrates the technology isn't sacrificing performance for cost savings.
For Ferroglobe specifically, this creates an opportunity to transition from being merely a commodity supplier to becoming a strategic battery materials provider, potentially commanding premium pricing for what would otherwise be standard metallurgical silicon output.
Strategic Funding Round to Scale Cell Production and Deliver Next-Generation EV Batteries to Global Automakers in 2025
This funding will go towards scaling Coreshell's production at its newly-built 4 MWh manufacturing facility in
"This strategic funding round is a critical step in scaling production and delivering commercial samples to leading automakers who have already tested the low-cost metallurgical silicon anodes in our cells with promising results and are eager to receive commercial-scale cells for further validation," said Jonathan Tan, CEO of Coreshell. "As the global EV industry reaches an inflection point, automakers recognize that alongside range, supply chain resilience - driven by reliance on foreign countries for graphite production - and cost reduction are key to overcoming adoption barriers. Coreshell is addressing these challenges by replacing graphite with domestically sourced metallurgical silicon, reducing costs, strengthening the supply chain, and improving sustainability."
Expanding to Meet Market Demand
Funding will accelerate Coreshell's efforts to meet the growing demand for its silicon-based batteries and will also be used to expand the company's executive and R&D teams to refine the production processes for its battery cells, which are made using standard equipment from
A Strong Strategic Partnership
As Coreshell's key materials partner, Ferroglobe provides the micrometric silicon essential for this breakthrough battery technology.
"Based on extensive validation by our team and rigorous lab testing, we believe Coreshell's battery technology shows the most promise to fast-track the EV industry in reducing cost and tackling supply chain issues," said Benoist Ollivier, Chief Technology & Innovation Officer of Ferroglobe. "Our strategic partnership and the excellent results from Coreshell's technology are the reasons why we've further invested in the company. This is a critical moment to scale a domestic supply chain and drive success in the market."
A Breakthrough in Battery Technology
Until now, no other battery company has been able to effectively unlock the power of metallurgical silicon. Coreshell has revolutionized the entire cell design by creating battery chemistries made with earth abundant materials adding 30+% more range while decreasing cost by up to
The test data of Coreshell's battery cells will be unveiled at the 2025 International Battery Seminar in March. A few key takeaways include:
- Energy Density: With 80 percent silicon anode, the cells provided 30
-40% higher energy density than graphite-based cells, offering a longer driving range with a smaller and lighter-weight battery. - Cycles: Prototype cells achieved over 475 cycles with greater than
90% of its original capacity and continue to cycle. Serial production cells are expected to exceed 1000 cycles to80% of original capacity. - Charging Rate: The battery consistently charged from 10 - 80 percent in under 15 minutes for hundreds of repeated cycles, delivering great fast-charging performance.
- Safety: Unlike many other silicon technologies, Coreshell's silicon anode batteries proved to be just as reliable and safe as traditional graphite-based batteries, but with significantly higher energy density.
