# Sila raises $300 million to scale battery anode production as AI and defense replace EV as growth engine > Source: > Published: 2026-07-22 08:34:33+00:00 *The Moses Lake-based silicon anode maker closed a $300 million round on July 21, 2026, led by Atreides Management and Sutter Hill Ventures, to fund Phase 2 of its Washington campus while the EV market it was built for stalls.* Battery materials startup Sila did not need the EV market to cooperate. On July 21, the company announced a $300 million private equity round to expand its Moses Lake, Washington manufacturing campus, even as federal EV tax credits have narrowed, U.S. EV registrations fell year-over-year in January 2026, and rival battery startups like SES AI and 24M Technologies have either cut projects or conducted mass layoffs. The round was led by Atreides Management and Sutter Hill Ventures, with 8VC, Bessemer Venture Partners, Matrix Partners, and funds advised by T. Rowe Price Associates all joining. What Sila has that those others don't is a customer base that extends well past the auto industry. Sila's flagship material, Titan Silicon, is a silicon-carbon compound that replaces the graphite in lithium-ion battery anodes, delivering up to five times the gravimetric energy capacity of conventional materials and charging in under ten minutes. That matters enormously for EVs. It matters just as much - more, for some buyers - for drones running military surveillance missions, autonomous robots in warehouses, satellites, and the AI server hardware that data centre operators are now stacking at a pace that has made them significant buyers of grid-scale batteries. As TechCrunch noted this week, Sila is explicitly bucking the EV slowdown, and the investor list suggests the market agrees. ## A factory built to scale Phase 1 of the Moses Lake campus came online in fall 2025. It was the first automotive-scale silicon anode plant in the country, sitting on 160 acres and running at 2 gigawatt-hours of annual capacity. Phase 2, which the $300 million is funding, targets a far more ambitious number: 250 gigawatt-hours over the next five years. That's a different league entirely. If Sila hits it, the facility would rank among the largest anode manufacturing operations in the world. That kind of scale doesn't come from any single customer segment. It comes from stacking EV contracts on top of aerospace on top of defence on top of whatever AI infrastructure buildout looks like in 2028. The defence angle is worth taking seriously. Sila's Titan Silicon is manufactured to NDAA-compliant standards in the U.S., which matters right now when the Pentagon is actively trying to reduce dependence on Chinese battery supply chains. Longer drone flight times, higher payload capacity, ultra-fast recharging in the field: these are exactly the performance gains a silicon anode delivers over graphite, and exactly what the defence procurement community is paying up for. Bessemer Venture Partners, one of the investors in this round, published its defence tech roadmap for 2026 this year, naming battery technology as one of five frontiers. That's not a coincidence. ## What the investor list actually says The more interesting story here is not the $300 million itself but what the investor composition reveals about where hard-tech capital thinks the battery market is going. T. Rowe Price-advised funds don't usually participate in early rounds for manufacturing startups. The fact that they're in alongside Sutter Hill, which has been backing Sila for years, signals that this is no longer being priced as a venture bet on a technology that might work. It's being priced as a scaling bet on a technology that already works, in a facility that's already producing, for customers that already include aerospace and consumer electronics players. That shift matters. The contrast with the rest of the field is stark. The Boston Globe reported in March 2026 that 24M Technologies conducted extensive layoffs and may be shutting down, while SES AI ended its EV battery development programmes entirely. Those two companies, along with others, raised nearly $1.4 billion combined. Now they're contracting. Sila has raised over $900 million in total and just opened its first factory. The difference is not purely the technology, though Titan Silicon is genuinely differentiated. It's the customer diversification strategy that Sila has been building for years, quietly positioning its anode material as an input for anything that needs a battery to be lighter, faster-charging, and more energy-dense - not just a car. For founders and investors watching where hard-tech capital is still moving in 2026, Sila is the clearest current data point. The EV tailwind that justified a lot of battery startup investment from 2020 to 2024 has weakened. What replaced it is a set of buyers - in AI infrastructure, robotics, and defence - that care more about performance per kilogram than cost per kilowatt-hour. Sila has spent ten years of materials science building toward exactly that. It just didn't know that was the market when it started. **Also read:** [Four Rapyd executives who scaled payments past $1 billion just raised $8 million to fix the chaos they lived through](https://startupfortune.com/four-rapyd-executives-who-scaled-payments-past-1-billion-just-raised-8-million-to-fix-the-chaos-they-lived-through/) • [Axiom Biosciences is skipping Nasdaq for Hong Kong and the math behind that call is hard to argue with](https://startupfortune.com/axiom-biosciences-is-skipping-nasdaq-for-hong-kong-and-the-math-behind-that-call-is-hard-to-argue-with/) • [Samsung is in talks to take an equity stake in Mistral AI as the French startup seeks €3 billion at a €20 billion valuation](https://startupfortune.com/samsung-is-in-talks-to-take-an-equity-stake-in-mistral-ai-as-the-french-startup-seeks-3-billion-at-a-20-billion-valuation/)
