Sila lands $1.4B Pentagon loan as militaries demand more batteries
Sila, a US battery materials startup, has secured a $1.4 billion loan from the Department of Defense to expand production of its silicon-carbon anode material. The deal, announced on Friday, comes as American automakers and defence contractors struggle to source battery materials outside China, which dominates the graphite anode supply chain that most lithium-ion batteries currently rely on.
Silicon-carbon anodes can store 20% to 40% more electricity than graphite, enabling longer-lasting or lighter batteries suited to drones, EVs and other defence and mobility applications. Sila produces the material at its Moses Lake, Washington factory, which began operating in September and currently makes about 2 gigawatt-hours annually; it is being expanded fivefold to supply more than 100,000 EVs. Sila, which has already raised over $1.5 billion privately and struck deals with Mercedes and Panasonic, could now also pursue defence contracts. The Pentagon simultaneously announced further critical-materials deals: a $400 million loan to Australia's Sunrise Energy Metals for scandium mining, $150 million to Niron Magnetics for rare earth-free magnets, and an $85 million equity stake in Strategic Bauxite.

- Move aims to cut reliance on China-dominated graphite supply chains
- Pentagon also backed three other critical-materials firms the same day
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Supporters argue that reducing dependence on Chinese-dominated battery supply chains is a genuine national security imperative, given how central lithium-ion and next-generation cells are to drones, communications equipment and soldier-worn power systems. They see the loan as a prudent use of the Pentagon's industrial-base authority to seed domestic manufacturing capacity that private markets alone have been slow to build at scale, mirroring past successful government investments in strategic technologies. From this view, the cost of inaction – remaining reliant on a strategic rival for critical materials – far outweighs the risk of the loan.
The case against
Critics who are equally serious about sound governance worry that the Pentagon is not well placed to underwrite commercial ventures, and that a $1.4 billion loan to a single company risks taxpayer money on a firm that may fail to scale or repay it. They caution against government picking winners in a competitive battery sector, arguing this could crowd out other promising firms, distort market signals, and set a precedent for defence-budget-funded industrial policy that escapes the scrutiny normal appropriations receive. For them, targeted tax incentives or broader, competitively awarded programmes would achieve the same security goals with less concentrated risk and better value for public funds.
