Coreshell Technologies Raises $30M Series B to Scale China-Free Batteries for U.S. Industries

Coreshell Technologies closed a $30 million Series B financing round co-led by Ferroglobe PLC & Access Industries, with participation from ADS, Helios Ventures, Pegasus Tech Ventures, Mana Ventures, & Entrada Ventures.
The funding aims to accelerate commercialization, scale manufacturing, & support customer programs to eliminate dependence on China for critical anode & cathode materials.
This investment builds upon a $50 million Department of Energy grant awarded in August 2026 to support domestic battery manufacturing.
Coreshell replaces conventional graphite, 90% of which is processed in China, with metallurgical silicon (MGS), a low-cost material produced domestically in the US.
The company is utilizing its federal grant to construct the first giga-scale factory for cells using MGS anodes.
Coreshell secured a long-term lithium agreement with L&F Co., Ltd. to ensure a Chinese-free cathode supply chain.
The technology addresses supply chain vulnerabilities highlighted by China's 2023 export controls & current federal sourcing requirements under the National Defense Authorization Act.
Defense sector partners, including ADS, cite the technology as vital for securing battery supply chains for uncrewed systems & reducing geopolitical liabilities.
Coreshell's proprietary design delivers higher performance & lower costs while leveraging abundant, domestically sourced critical minerals.
