US battery materials company Sila has raised $300 million in private equity to increase production of its silicon-carbon anode material and support the second phase of its Moses Lake factory in Washington state.
The funding round was led by Atreides Management and Sutter Hill Ventures. Other participants included 8VC, Bessemer Venture Partners, Matrix Partners, funds and accounts advised by T. Rowe Price Associates and other new and existing investors.
Sila said the investment would accelerate US production of Titan Silicon, its silicon-carbon anode material, for applications including electric vehicles, consumer electronics, drones, satellites, robotics and data centres.
The company began operations at the Moses Lake plant in September 2025 and is now ramping production. Sila describes the first phase as having 2GWh of annual capacity and said the 160-acre site had been designed to expand to as much as 250GWh over the next five years.
When the facility opened, Sila gave its initial capacity as 2–5GWh. It has not disclosed the capacity or timetable planned for the second phase supported by the latest investment.
Sila: further scaling its operations
Gene Berdichevsky, co-founder and CEO of Sila, said: “This funding allows 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.”
The company claims Titan Silicon can provide 20–40% higher energy density than conventional graphite anodes, allowing batteries to store more energy or be made smaller and lighter. It also claims the material can support faster charging.
Silicon has a much higher theoretical capacity than graphite but expands and contracts substantially as a cell is charged and discharged. Silicon-carbon composites are intended to manage these volume changes sufficiently for the material to replace some or all of the graphite in a lithium-ion cell.
Sila has agreements to supply Titan Silicon to Panasonic Energy and Mercedes-Benz. Mercedes-Benz previously selected the material for a future electric G-Class model.
Vic Miller of Sutter Hill Ventures said: “We have watched them translate 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.”
The latest investment follows a $375 million funding round announced by Sila in June 2024. The Moses Lake project was also selected in 2022 for a $100 million grant from the US Department of Energy under the Bipartisan Infrastructure Law.
At the time of that award, the department described a planned 600,000-square-foot (56,000 m2) factory producing enough anode material for 200,000 electric vehicles annually. Sila said in 2025 that it expected to hire and train as many as 500 people at the site over three to five years.
