Sila’s Moses Lake, Washington, factory is operating and ramping production of Titan Silicon, the company’s silicon-carbon anode material for lithium-ion batteries. The opening was not proof of full-rate manufacturing or customer deliveries: Sila said the initial work involved refining process recipes, and its July 2026 update described production as ramping without giving output volumes. The plant is intended to supply automakers and battery makers, with Mercedes-Benz named as an expected early customer.
What the Moses Lake factory makes
The plant makes Titan Silicon, Sila’s silicon-carbon (Si/C) anode material. An anode is one of the electrodes inside a lithium-ion cell; Titan Silicon is a battery material, not a complete battery, an EV part sold to consumers, or a vehicle accessory. Sila says it is designed to replace graphite in battery anodes and serve automotive and other original-equipment-manufacturer applications. Sila’s September 2025 opening announcement and its manufacturing overview describe the product and facility.
How silicon anodes could affect EV batteries
Replacing some or all of a graphite anode with silicon-based material is intended to increase how much energy a cell can store for a given size or weight. If a finished battery pack uses cells with higher energy density, an automaker could use the added capacity for more driving range, or use a smaller or lighter pack for a similar range. Sila also says Titan Silicon can enable faster charging. Those are potential cell- and pack-level benefits, not a guarantee of a particular range or charging improvement in a production vehicle.
Sila has published two performance comparisons, and their baselines differ. In September 2025, the company claimed Titan Silicon could deliver up to 20% greater energy density than the industry’s best-performing graphite cells. In July 2026, it described its Si/C anode as delivering 20–40% higher energy density than traditional graphite. Both are company claims; the sources cited here do not provide independent, like-for-like test results to verify either figure. Sila’s July 2026 announcement gives the later comparison.

What “opened” means—and what it does not
Sila announced the start of operations at Moses Lake on September 23, 2025. The company said the early work would test and refine manufacturing recipes before initial batches of Titan Silicon. In a July 21, 2026 update, Sila said the plant had begun operations in fall 2025 and was ramping production. Taken together, those updates establish that the factory is operating and moving through a production ramp; they do not establish a particular volume of finished material, sustained full-rate production, or customer deliveries from the site.
The distinction matters because an industrial plant moves through stages: commissioning and process development, initial batches, product qualification with customers, and then sustained commercial production. Announcing operations or a ramp does not by itself show that every later stage is complete. The sources cited here do not report Moses Lake output volumes or confirm material deliveries from the factory to vehicles.
Plant size, capacity figures, and expansion plans
Sila says the Moses Lake site covers 160 acres and contains more than 600,000 square feet of manufacturing space. Its capacity figures have changed in wording and scope over time. They are design capacities or company targets, not reported production:
| Figure | What it describes | How to read it |
|---|---|---|
| 2–5 GWh | Initial capacity in Sila’s September 2025 opening announcement. | A company-stated initial-capacity range, not measured output. |
| 2 GWh | Phase 1 initial capacity in Sila’s July 2026 update. | A later company description of Phase 1; it is not the same figure as the 2025 range. |
| Up to 100 GWh by 2030 | Capacity listed on Sila’s manufacturing page, accessed in 2026. | A company-stated capacity target and date. |
| As much as 250 GWh within five years | Expansion potential described in Sila’s 2025 and 2026 statements. | A company-stated longer-term design or expansion target, not achieved capacity. |
| 20 GWh-equivalent at project conclusion in 2026 | A production projection in the U.S. Department of Energy’s 2022 project fact sheet. | An earlier federal project expectation, not confirmation that the plant reached this output. |
The figures should not be treated as interchangeable: they refer to different announcements, phases, time horizons, and types of projection. Neither the stated site size nor a planned GWh capacity establishes how much material the factory has produced. Sila’s opening announcement, July 2026 update, manufacturing page, and the DOE’s 2022 fact sheet give the respective figures.

The DOE’s 2022 project fact sheet identified Mercedes-Benz as the intended first commercial customer and the G-Class as the planned initial vehicle line. In September 2025, TechCrunch reported that Sila had supply agreements with Mercedes-Benz and Panasonic. These are announced customer relationships or plans; they do not establish that Titan Silicon from Moses Lake has already been delivered to either company or used in a production vehicle. TechCrunch’s September 2025 report provides the supply-agreement context.

The DOE’s 2022 fact sheet listed a $100 million federal cost share and a $300 million recipient cost share for the Auto Scale Silicon Anode Plant. It also projected 20 GWh-equivalent full production by the project’s conclusion in 2026. Those amounts and the production figure describe the project as planned in 2022, not a later verified outcome.
On July 21, 2026, Sila announced a separate $300 million private equity round, saying it would accelerate U.S. production and support a planned Phase 2 expansion. The funding announcement is not itself evidence that the expansion has been completed or that a particular production volume has been reached. Sila’s statements about the financing and expansion appear in its July 2026 announcement.
