Sila Raises $300M to Fast-Track Gigascale Anode Production and Shore Up US Battery Supply Chains
Sila, the battery materials company formerly known as Sila Nanotechnologies, has raised $300 million in a private equity round led by Atreides Management and Sutter Hill Ventures to expand its silicon anode manufacturing plant in Moses Lake, Washington. 8VC, Bessemer Venture Partners, Matrix Partners, T Rowe Price, and existing investors including In-Q-Tel also participated. The round brings total funding to well above $1 billion.
Silicon anode technology offers a significant advantage over conventional graphite anodes by storing roughly 20 percent more energy by weight. Sila’s Titan Silicon was the first commercial silicon anode material to reach consumers when it launched inside the WHOOP fitness band in 2021. Mercedes-Benz has named the electric EQG as the first vehicle to use the material, but no automotive batteries containing Titan Silicon have yet shipped.
The Moses Lake facility spans 160 acres, opened in the fall of 2025, and currently operates at a capacity of 2 gigawatt-hours during Phase 1 production. The $300 million will fund Phase 2 expansion, aiming to reach 250 gigawatt-hours over five years.
China dominates global anode material processing and battery cell production, controlling more than 90 percent and 80 percent respectively, according to figures from the Department of Energy and International Energy Agency. Sila’s Moses Lake plant positions itself as a domestic alternative, utilizing silane gas supplied by REC Silicon under a long-term agreement instead of relying on Chinese graphite.
This round arrives as next-generation battery technologies gain increasing attention, with US defense and intelligence agencies recognizing domestic battery material supply as a national security priority.
