Coreshell secures $24 million to expand production of lithium-ion battery cells using domestically sourced silicon anodes, aiming to lower costs and enhance energy density for electric vehicles. The funding supports scaling operations at its new facility and developing a larger manufacturing site to meet industry demand. Automakers testing the technology report improved performance, faster charging, and supply chain advantages over traditional graphite-based batteries.
Silicon Anodes Reshape the EV Battery Market
Electric vehicle manufacturers are searching for alternatives to graphite-based anodes to improve battery efficiency and lower costs. Silicon anodes offer a higher energy density, but their widespread adoption has been limited by technical challenges, including expansion during charging cycles.
Graphite anodes remain the industry standard, but reliance on foreign sources for raw materials creates supply chain vulnerabilities. A shift toward domestically produced silicon anodes reduces dependence on external suppliers while enhancing battery performance. Coreshell’s approach centers on using metallurgical-grade silicon, a cost-effective material that increases energy density without requiring extensive refinement.
Battery makers seeking improved performance and affordability are evaluating silicon-based alternatives. Energy storage capacity, charging speeds, and production costs influence decisions in a competitive EV market.
Coreshell’s $24M Funding Boosts Next-Generation Battery Production
Coreshell secured $24 million in new funding to expand its lithium-ion battery manufacturing capabilities. The round included strategic investments from Ferroglobe PLC and Zeon Ventures, along with backing from Lane Ventures, Entrada Ventures, Foothill Ventures, Helios Climate Ventures, and others.
The funding will support production at Coreshell’s recently completed 4 MWh facility in San Leandro, California. To scale further, the company is designing a 100 MWh facility, currently in site selection. This expansion aims to supply growing demand from automakers requiring commercial-scale samples of silicon anode cells.
With financial support from industry leaders and venture capital firms, the company plans to accelerate manufacturing while refining its battery technology for mass production.
Why Automakers Turn to Coreshell’s Silicon Anode Technology
Coreshell’s battery cells integrate silicon anodes without requiring major changes to existing manufacturing processes. The 60 Ah cells provide a 30–40% higher energy density than graphite-based counterparts. This increase in capacity allows for longer vehicle range without adding significant weight.
Prototype tests indicate the cells retain more than 90% of their original capacity after 475 cycles, with expectations to exceed 1,000 cycles at 80% retention in commercial production. Charging from 10% to 80% takes under 15 minutes over repeated cycles, aligning with the push for faster charging solutions in EVs.
The ability to manufacture high-performance cells at a lower cost than graphite alternatives makes silicon anodes attractive to automakers. Reducing dependency on imported graphite also strengthens the supply chain, an ongoing concern in the industry.

The Strategic Partnerships Powering Coreshell’s Growth
Ferroglobe supplies the micrometric silicon essential for Coreshell’s anode technology. The partnership ensures a stable source of domestically produced silicon, an alternative to graphite imported from overseas.
Venture capital firms and industry investors have contributed financial backing to bring the technology to commercial scale. Testing by multiple automakers has yielded positive results, supporting further investment in development and production.
Strategic alliances help Coreshell streamline manufacturing and prepare for large-scale adoption. Battery makers and automakers evaluating silicon anodes for future production rely on these partnerships to mitigate supply risks and cost challenges.
Scaling Production Without the Need for Specialized Infrastructure
Coreshell’s battery cells use standard equipment from South Korea’s TopMaterial, allowing manufacturers to integrate silicon anode production without modifying existing facilities. This capability removes a major barrier to entry, making it easier for automakers and battery suppliers to incorporate the technology.
Producing high-performance cells without specialized infrastructure reduces costs and shortens development timelines. Manufacturers gain a pathway to improve battery efficiency while maintaining existing supply chains.
By leveraging available manufacturing technologies, the company is positioned to deliver silicon anode batteries at scale without requiring a complete overhaul of production methods.
What This Means for the Future of EV Batteries
Silicon anodes have long been considered a key advancement for lithium-ion batteries. Coreshell’s ability to commercialize this technology at a competitive cost could shift industry adoption toward silicon-based alternatives.
Domestic production of battery materials strengthens supply chains by reducing reliance on foreign-sourced graphite. Automakers integrating silicon anodes can lower costs while improving battery performance, contributing to wider EV adoption.
The company plans to distribute commercial samples to global automakers in 2025, with expanded manufacturing capacity expected to follow. Testing and validation from industry leaders will determine how quickly silicon anode technology becomes a standard in next-generation electric vehicles.
