Not yet—and it is not a like-for-like contest. Sila makes silicon-carbon anode material for battery makers; established manufacturers such as CATL sell complete batteries at enormous scale. Sila could become an important supplier if it scales production, proves performance in customer cells, and wins sustained commercial demand. But the available figures show a developing materials business, not leadership of the overall battery industry.
What Sila makes—and what it does not
Sila’s Titan Silicon is a silicon-carbon anode material for lithium-ion batteries. The anode is one of a cell’s electrode materials. Sila’s proposition is to replace graphite with a silicon-based composite intended to improve energy density and charging performance. The company says Titan Silicon entered the market in 2021 and is designed for automotive, consumer-electronics, industrial, and other applications.
This makes Sila a business-to-business materials supplier, not a maker of retail batteries for consumers. Its potential reach depends on cell and equipment manufacturers incorporating the material into products and qualifying those products for use.

How Sila’s silicon anode compares with graphite
Sila says Titan Silicon can enable higher energy density than graphite-based cells and can support faster charging. Its published figures vary by announcement: in September 2025, the company claimed up to 20% greater energy density than the industry’s best-performing graphite cells; in July 2026, it described 20–40% higher energy density than traditional graphite. These are company claims from different announcements, not one independently established performance range.
#1 Best Overall
- Energizer Double A Lithium batteries are the world's longest lasting AA batteries.
- These AA Energizer batteries power your most critical devices, great for smart home devices, outdoor surveillance systems, digital cameras, Blink outdoor cameras, and handheld games
- An Ultimate Lithium battery can hold power up to 25 years in storage for trustworthy backup energy, so you are always prepared
- Energizer lithium AA batteries are made with leak-proof construction to help protect devices (based on standard use)
- AA lithium batteries can perform in extreme temperatures from -40F to 140°F for year-round, indoor and outdoor use
The figures should not be treated as a direct comparison with every graphite or silicon-anode product. The available announcements do not provide a matched, independent cell test comparing Sila’s material with graphite and competing silicon-anode materials. A material-level claim also does not, by itself, establish the range, charging time, cost, or life of a finished EV battery; those outcomes depend on the cell and vehicle in which it is used.
Is Sila manufacturing at scale?
Sila says its Moses Lake, Washington, facility began operations in fall 2025. Its September 2025 opening announcement described staff testing and refining process recipes, with initial material batches to follow. In July 2026, the company said construction was complete and production was ramping from an initial Phase 1 capacity of 2 GWh. That is a company-reported anode-material capacity expressed as battery-capacity equivalent; it is not a report of 2 GWh of complete batteries sold or delivered.
The capacity description has changed across company publications. Sila’s September 2025 announcement said Phase 1 could support 2–5 GWh of battery capacity, while its July 2026 announcement described an initial 2 GWh. The difference is a reason to attach each figure to its publication rather than present a single settled output figure. Neither announcement establishes full-rate production, manufacturing yield, or customer delivery volumes.

- 8 pack of Energizer Ultimate Lithium AA Batteries
- Energizer Ultimate Lithium AA batteries are the world's longest lasting AA batteries
- Performs in extreme temperatures from -40 degrees F to 140 degrees F to ensure reliable use in all seasons
- These double A batteries are leak proof batteries, guaranteed based on standard use
- Lightweight household batteries last up to 25 years in storage
Expansion targets are not current output
Sila has outlined much larger future capacity plans, but the figures are targets:
- Its September 2025 plant-opening announcement said the facility could expand to 250 GWh within five years.
- Its July 2026 announcement described expansion up to 250 GWh over the next five years.
- The company’s manufacturing page separately lists up to 100 GWh of anode capacity by 2030.
These statements refer to planned expansion, not achieved capacity. The publications do not reconcile the 250 GWh target with the separate 100 GWh-by-2030 figure, so they should be read as distinct company-published plans rather than combined into a confirmed production forecast.
What the Moses Lake facility establishes
Sila describes the site as 160 acres with more than 600,000 square feet of space. Its manufacturing page says the facility has ISO 9001-certified quality frameworks and identifies U.S.-based suppliers including REC Silicon, Norco, Airgas, and Linde. These details indicate investment in domestic manufacturing infrastructure; by themselves, they do not establish competitive cost, production yield, or reliability.

How Sila compares with an established battery maker
CATL is a useful scale benchmark, but it occupies a different position in the value chain. Sila supplies anode material; CATL manufactures and sells complete batteries. CATL’s announcement of its 2025 annual report, published March 10, 2026, reported the following figures for the 2025 reporting year:
| Measure | Sila | CATL |
|---|---|---|
| Business position | Supplier of silicon-carbon anode material (Sila company materials) | Manufacturer and seller of lithium-ion batteries (CATL 2025 annual-report announcement) |
| Reported production or sales scale | Production ramp from initial 2 GWh Phase 1 capacity, expressed as battery-capacity equivalent (Sila, July 2026); delivered volume not stated in that announcement | 661 GWh of lithium-ion battery sales in 2025 (CATL, March 10, 2026) |
| Reported production capacity | Initial 2 GWh Phase 1 capacity, expressed as battery-capacity equivalent (Sila, July 2026) | 772 GWh in 2025, with 321 GWh under construction at year end (CATL, March 10, 2026) |
| Reported market share | Not stated in the cited Sila announcements | 39.2% global power-battery market share in 2025, attributed by CATL to SNE Research |
The table compares different kinds of figures: Sila’s is anode-material capacity expressed as a battery-capacity equivalent, while CATL’s are battery sales and battery production capacity. They show the scale gap, but they do not show that one company is better at making the same product.
The broader EV battery market is also concentrated. CATL’s 2024 industry overview, published in 2025 and citing GGII and SNE Research, said the top five companies accounted for 74.7% of global EV battery usage volume in 2024, and the top ten accounted for 89.4%. Those shares describe battery usage volume, not anode-material supply. They help explain the scale, customer, and supply-chain advantages incumbents bring to the cell market.

Which companies are connected to Sila’s commercial plans?
A U.S. Department of Energy project fact sheet from 2022 named Mercedes-Benz as the planned first commercial customer served by Moses Lake. It said Mercedes-Benz had selected Sila’s anode material for future electric vehicles, starting with the G-Class series, which the fact sheet then expected to be released in the middle of the decade. That timing was an expectation in a 2022 document, not confirmation of a current vehicle launch or material-delivery schedule.
Sila’s current press page also names Mercedes-Benz and Panasonic Energy in connection with intended automotive uses. GeekWire’s September 2025 report referenced partnerships with both companies. These sources establish announced commercial programs and intended uses; they do not establish how much material is being delivered, when production deliveries will begin, or what share of a production battery will use Sila material.

That dated report is not enough to rank today’s silicon-anode suppliers or declare a winner.
What would show that Sila is becoming a leader?
Leadership depends on the metric. Sila could become influential in advanced anode materials without becoming a leading producer of complete batteries. To assess whether its position is strengthening, look for evidence on comparable measures rather than relying on headline capacity targets or material claims:
- Cell performance: energy density and charging time measured in comparable cells and under disclosed test conditions.
- Durability and safety: battery-life and safety results for customer-qualified products, not just the intended benefits of the material.
- Economics: cost per usable kWh and the costs of making the material at commercial volumes.
- Manufacturing execution: achieved output, yield, quality consistency, and whether expansion occurs on schedule.
- Commercial traction: customer qualification, production programs, and disclosed deliveries that continue beyond an announced partnership.
- Resilience: the ability to maintain supply as production expands and as geographic or supply-chain risks change.
The available figures do not provide comparable results across these measures. Sila’s case therefore rests on whether its material can move from a promising product and a production ramp into reliable, cost-competitive supply at volumes customers actually use.
