Sila Nanotechnologies has secured a $1.4 billion loan from the U.S. Department of Defense to expand production of its silicon-carbon battery anode material at its Moses Lake, Washington factory. The funding addresses growing demand for battery materials sourced outside China, where most graphite anode supply chains are concentrated. Silicon anodes offer 20–40% greater energy density than graphite, making them attractive for EVs, drones, and defense applications. The factory currently produces ~2 GWh of anode material annually; the expansion aims for a fivefold increase, enough for over 100,000 EVs. Sila also raised $300M in private funding in July and has existing deals with Mercedes and Panasonic. The Pentagon simultaneously announced loans to three other companies targeting scandium mining, rare-earth-free magnets, and bauxite.
Questions this post answers
How much more energy can silicon anodes store compared to graphite anodes?
Silicon anodes can store 20% to 40% more electricity than graphite anodes. This improved energy density enables either longer-lasting battery cells or smaller, lighter batteries — both valuable for defense applications like drones and for EV mobility. Multiple companies including Sila, Group14, and Amprius are pursuing silicon anode technology as an alternative to graphite, whose supply chain is dominated by Chinese companies. Engineers evaluating battery material choices for EVs or defense hardware track developments like this on daily.dev.
What is the current production capacity of Sila's Moses Lake Washington factory?
Sila's Moses Lake, Washington factory, which began operating in September, can currently produce about 2 gigawatt-hours of anode material annually. Sila is working to expand the factory fivefold, which would allow it to produce enough silicon-carbon anode material for more than 100,000 EVs per year.
