Sila has begun operations at its new silicon-anode manufacturing facility in Moses Lake, Washington. The site is now testing and refining process recipes and will soon begin producing initial batches of its silicon-carbon (Si/C) anode material, Titan Silicon, for use in electric vehicles (EVs), as well as other applications such as electronics, aerospace, and grid storage.
The Moses Lake facility represents a significant step in building out the domestic battery materials supply chain.
At full scale, the plant is expected to reach up to 250 GWh of capacity within five years, with initial operations supporting 2 to 5 GWh. The facility spans more than 600,000 square feet across 160 acres and is powered by hydropower from the Columbia River.
Silicon anodes are designed to replace graphite, which is currently the dominant but heavily imported anode material in lithium-ion batteries. By shifting to silicon-carbon anodes, battery makers can achieve higher energy density and improved charging speeds, which are factors that are particularly relevant for EVs, where range, charging time, and safety remain central engineering challenges.
Industry experts view the Moses Lake facility as a key milestone in domestic production capacity for advanced battery materials. Today, most of the world’s anode material is produced overseas. Establishing large-scale manufacturing in the US has the potential to strengthen supply resilience and reduce reliance on critical minerals sourced abroad.
In addition to its technical focus, the facility is designed with safety and environmental responsibility in mind, incorporating process safety systems and automotive-grade quality controls. The company is also working with local colleges and vocational programs to build a pipeline of skilled workers, with plans to employ up to 500 people as operations scale.
Sila first introduced silicon anode technology more than a decade ago, pioneering efforts to push beyond the limits of conventional lithium-ion cells. With Moses Lake now in operation, the company is demonstrating how advanced materials can move from the lab to large-scale manufacturing and ultimately support the broader adoption of EVs.
