Sila raises $300M to expand battery materials output in Washington

Sila raised $300 million to scale silicon-carbon anode production in Moses Lake.

Why it matters: The deal is a large bet on battery-materials capacity while U.S. EV demand has softened. It also adds domestic supply in a part of the battery chain still seen as a bottleneck for automakers.

  • Sila said July 21, 2026 that it raised $300 million in private funding.
  • The money will expand its Moses Lake, Washington plant and accelerate U.S. production of Titan Silicon.
  • Sila says the expansion should lift output to tens of gigawatt-hours per year, enough to support more than 100,000 EVs.
  • The round was led by Atreides Management and Sutter Hill Ventures, with participation from 8VC, Bessemer Venture Partners, Matrix Partners and T. Rowe Price-advised funds/accounts.

Sila is pressing ahead with capacity expansion even as U.S. EV adoption has cooled. The company said the new capital will help ramp its silicon-carbon anode technology, Titan Silicon, at its Moses Lake, Washington plant, which began operations on September 23, 2025. Sila's press release says the financing supports a planned Phase 2 expansion.

TechCrunch reported the plant had previously been described as capable of making up to 2 gigawatt-hours of silicon-carbon anode material, while the new expansion is expected to increase output to tens of gigawatt-hours annually. The report said that would be enough anode material to support more than 100,000 EVs.

The company is pitching Titan Silicon as a higher-performance alternative to graphite anodes. Sila says the material can store up to 40% more energy than traditional graphite anodes and charge faster. The funding also fits a broader U.S. supply-chain push around battery materials and domestic manufacturing.

The raise comes against a softer U.S. EV backdrop. Cox Automotive said EVs accounted for about 5.8% of U.S. new-vehicle volume in Q2 2026, down from 10.6% at the Q3 2025 peak. Its report said the market stabilized in the quarter, but at a lower share than last year.

By the numbers

  • 300 million - amount Sila said it raised in private funding
  • 5.8% - share of U.S. new-vehicle volume that EVs represented in Q2 2026, per Cox Automotive
  • 100,000+ - EVs Sila says the expanded output could support

Yes, but: The company has not publicly disclosed a valuation here, and the exact pace of the Phase 2 expansion and any customer commitments are not detailed in the available sources.

What's next: Sila has said the money supports a planned Phase 2 expansion at its Moses Lake plant, but the sources do not give a construction timeline.
