Sila raises $300M to scale US silicon battery anode manufacturing

Sila announced a $300 million（約480億円） private funding round to expand production of its Titan Silicon® anode technology at its Moses Lake, Washington manufacturing facility. The round was led by Atreides Management and Sutter Hill Ventures, with participation from 8VC, Bessemer Venture Partners, Matrix Partners, and funds advised by T. Rowe Price Associates, Inc. The company will use the capital to support a planned Phase 2 expansion of the Moses Lake plant and accelerate production of its silicon-carbon anode technology.

Anodes have become strategically important as policymakers recognize that battery material supply chains carry significant national security implications. China currently dominates global anode material processing and battery cell manufacturing, creating concentration risk for industries including drones, defense systems, satellites, sensors, AI infrastructure, robotics, consumer electronics, and electric vehicles. Sila's silicon-carbon anode is engineered to replace traditional graphite anodes in lithium-ion batteries and delivers 20% to 40% higher energy density while supporting faster charging. For the drone industry, these improvements are particularly valuable: higher energy density translates into longer flight times, greater payload capacity, or smaller battery packs for the same mission—advantages that matter most in long-range inspection, public safety, defense, and autonomous operations.

Sila began operations at its Moses Lake facility in fall 2025. The 160-acre site currently operates with Phase 1 capacity of 2 GWh. The company plans to expand the facility over the next five years to as much as 250 GWh of annual capacity, which if completed would make it the world's largest anode production facility. The expansion is also expected to create hundreds of manufacturing jobs in Washington State. Vic Miller of Sutter Hill Ventures commented that Sila's transition "from a groundbreaking material science inventor to a gigascale manufacturing company is a masterclass in American operational discipline," noting that the company had "translated laboratory breakthroughs into reality, proving that the leap from the lab to the factory floor is not only essential, but achievable in the United States with the right technology and team." Gene Berdichevsky, Sila Co-Founder and CEO, stated that the funding would "allow us to further scale our operations and deliver on the promise of American innovation, strengthen the foundation of our domestic manufacturing capabilities and ensure that critical industries have a secure and reliable supply of advanced batteries."

Battery materials have emerged as a critical national security and supply chain issue, yet much policy discussion has focused narrowly on battery cells rather than the full component ecosystem. Anodes—the negative electrode in lithium-ion batteries—are equally essential, and their production remains heavily concentrated in China. This concentration creates vulnerability across multiple strategic industries: drones, defense systems, satellites, sensors, AI infrastructure, robotics, and electric vehicles all depend on advanced battery performance. For the drone industry specifically, anode quality directly impacts operational capability; higher energy density translates into longer flight times, greater payload capacity, or lighter battery packs—all critical advantages for long-range inspection, public safety, and autonomous operations.

Sila's approach combines proprietary material science with gigascale U.S. manufacturing. The company completed its Moses Lake facility in fall 2025 and is now pursuing a planned expansion that would grow capacity from 2 GWh to as much as 250 GWh over five years. If achieved, this would position Moses Lake as the world's largest anode production facility. The $300 million（約480億円） funding round—led by Atreides Management and Sutter Hill Ventures and supported by established venture and institutional investors—signals investor confidence that the leap from laboratory breakthroughs to commercial manufacturing is achievable in the United States. The timing aligns with broader U.S. policy emphasis on secure domestic sourcing for critical technologies; manufacturers and defense planners are increasingly viewing supply chain resilience as inseparable from technology leadership.
