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

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.
