US battery-materials pioneer Sila Nanotechnologies announced on July 21 that it has raised $300 million in private funding to expand its Moses Lake, Washington factory into a gigascale supplier of silicon-carbon anode material. The round was led by Atreides Management and Sutter Hill Ventures with participation from 8VC, Bessemer Venture Partners, Matrix Partners and T. Rowe Price.
From 2 GWh To Tens Of Gigawatt-Hours
Sila's Moses Lake plant — the western world's first automotive-scale silicon-anode facility, opened in September 2025 — currently makes up to 2 GWh of Titan Silicon material per year. The Phase 2 expansion funded by the new round will push that to tens of gigawatt-hours annually, enough anode material to power more than 100,000 electric vehicles.
Silicon Bets Against A Softening U.S. EV Market
The raise arrives even as U.S. EV sales soften post-tax credit sunset. Global EV sales are still up 27% year-over-year, according to Benchmark Minerals, and Sila's anode is one of the few non-Chinese alternatives to graphite at meaningful scale. Chinese suppliers control roughly three-quarters of the graphite anode chain, and Sila's Titan Silicon offers up to 40% more energy density and faster charging as a drop-in replacement. Sila also supplies Mercedes-Benz, Panasonic, Whoop, drone makers and satellite companies.
Batteries For Data Centers, Not Just Cars
Grid-scale storage is emerging as a second growth vector: AI data centers now purchase battery packs as backup and peak-shaving assets, echoing the buildout logic behind partnerships like PowerCell's 300 MW hydrogen deal for AI data centers. Sila's total capital raised now sits north of $1.6 billion, and the company positions the Moses Lake expansion as U.S. technology-sovereignty infrastructure.
