A Better Anode, Made in America
Nearly every lithium-ion battery cell in the world relies on graphite. This means that every EV, drone, and defense system running on lithium-ion batteries depends on a critical mineral that’s more than 90% controlled by China.
Coreshell’s exclusive, patented technology replaces graphite with metallurgical silicon (MGS) that’s sourced and processed in the US, delivering not only better performance but also a supply chain this country actually controls.

Metallurgical Silicon: Better Performance, Abundantly Available in the US

Coreshell's MGS anode offers two advantages over legacy graphite anodes.
Performance:MGS has 10x higher energy density than graphite, meaning more range per charge and more power and capacity at a lower weight. Silicon anodes also beat graphite in fast-charge, due to silicon’s voltage and volumetric properties.
Availability:MGS is inexpensive and already produced abundantly in the US. Coreshell sources its silicon domestically through a long-term partnership with Ferroglobe, eliminating the graphite’s mining and processing bottlenecks.
| Property | Legacy Graphite Anodes | |
|---|---|---|
| 01Supply Chain Resiliency | Dependent on Chinese critical minerals, exposed to export controls and geopolitical risk | Domestic supply, NDAA and FEOC compliant, free of Chinese critical minerals |
| 02Energy Density | Well-established capacity ceiling | 10x higher than graphite |
| 03Weight | Requires more active material by mass to deliver the same capacity | Higher gravimetric capacity supports lighter anodes and longer vehicle range |
| 04Cost | Increasingly volatile pricing amid trade restrictions | Cheaper to process than graphite, 20x cheaper than synthetic silicon |
Other “Silicon Anodes” are Actually Expensive Synthetics
Other “silicon anodes” still rely on graphite. Their silane-derived silicon can cost up to 20x more than Coreshell’s MGS. The rest is graphite, keeping their supply chains dependent on China.
Competitors’ synthetic “silicon”
- Energy intensive and unscalable
- Metal converted to gas, then condensed back into solid structures
- 10x - 20x more expensive than metallurgical silicon
Coreshell Metallurgical Silicon
- Abundant and already mass-produced in U.S.
- Mined in Alabama, refined in Ohio
- Cheaper and more energy dense than Chinese graphite
Built for the lines you already run.
Coreshell integrates with existing lithium-ion manufacturing lines, with no redesign required.
For EV and mobility manufacturers, higher energy density means longer range without added weight or cost. For drone and UAV programs, it means more flight time and payload capacity in the same battery size. For defense platforms, it means a domestically sourced, NDAA-compliant anode that offers real supply chain resilience.
Every OEM carries supply chain risk from the moment they select legacy batteries with graphite anodes. In our age of geopolitical uncertainty, that risk is no longer theoretical. Coreshell liberates OEMs from that risk.
