CarbonScape Limited (“CarbonScape”), a deep-tech innovator producing high-performance graphite for batteries, announces the issuance of a key U.S. patent (Patent No. US12187615B2). This milestone strengthens CarbonScape’s position as a leader in alternative graphite production and accelerates its U.S. expansion—addressing the geopolitical, economic and environmental challenges of today’s electric vehicle (EV) battery supply chain.
Revolutionizing battery-grade graphite production
CarbonScape’s newly awarded “Composition of Matter” patent protects its novel method for producing high-quality graphite from biochar, a carbon-rich byproduct of biomass. Instead of relying on resource-intensive mining or costly synthetic processes, CarbonScape’s proprietary technology converts biochar and other compounds into a low-surface-area graphite, ideal for lithium-ion battery anodes, critical to EV and energy storage systems.
“Securing this U.S. patent is a major milestone that confirms our technology’s unique value proposition,” said Vincent Ledoux-Pedailles, Chief Commercial Officer of CarbonScape. “By localizing a cost-competitive graphite supply in the U.S., using domestic forestry resources, we provide manufacturers’ with a stable, scalable and sustainable alternative —while mitigating environmental impact and supply-chain risks.”
Strengthening the U.S. battery supply chain
With demand for EV batteries surging and graphite production near zero, CarbonScape’s entry into the U.S. market provides a timely and strategic solution. Currently, China dominates 95% of global battery-grade graphite supply, creating cost volatility and supply-chain vulnerabilities for U.S. manufacturers. By harnessing regionally available biomass and leveraging favorable policy conditions, CarbonScape is positioned to become a leading source of domestic, renewable battery-grade graphite.
- Abundant Renewable Feedstock: CarbonScape has secured agreements to source commercial volumes of woodchips in the U.S. The robust forestry sector, particularly in the Southeast, guarantees reliable and cost-competitive inputs to support large-scale graphite production, whilst the agreements add resilience and renewed economic opportunity to the U.S. forestry industry.
- Supportive Policy & Public Funding: The U.S. government has prioritized domestic critical minerals through the Department of Energy (DOE) and Department of Defense (DOD) initiatives, high import tariffs on Chinese graphite and executive orders supporting strategic material development. These policies align with CarbonScape’s mission to establish a secure U.S. graphite supply chain.
- Streamlined Permitting & Regulation: Compared to many global jurisdictions, the U.S. offers a relatively efficient and flexible regulatory process for industrial projects. Federal support for domestic critical mineral developments enhances CarbonScape’s ability to scale production rapidly.
By leveraging these advantages, CarbonScape provides U.S. battery manufacturers with a secure, eco-friendly graphite alternative that reduces geopolitical risk, shortens supply chains, and aligns with federal initiatives for energy independence.
Recent advancements & future outlook
CarbonScape’s U.S. patent follows a series of breakthroughs in sustainable graphite production. In its latest production update, the company achieved a 90% spheroidization yield—an industry-leading metric demonstrating the efficiency of its proprietary process for converting raw graphite feedstock into battery-grade graphite. Additionally, CarbonScape continues to expand its renewable feedstock supply agreements across the U.S., ensuring a stable supply of critical materials to support the nation’s rapidly growing battery manufacturing and electric mobility sector.
As the U.S. accelerates its transition to electrification, CarbonScape’s technology offers a game-changing solution—securing a domestic, low-cost and sustainable graphite source for next-generation batteries.
