US Department of Defense $1.4 Billion Loan Supports Sila’s Silicon Battery Expansion for Military Drones and Autonomous Systems

Department of Defense $1.4 Billion Loan Supports Mass Production of Silicon Anode Technology

On August 7, the US Department of Defense announced a $1.4 billion conditional loan to battery materials technology company Sila to expand its production facilities in Moses Lake, Washington State. The funds will be used to increase the output of Sila’s proprietary Titan Silicon silicon-carbon anode material and establish a new lithium-ion battery cell manufacturing line to meet urgent demand for high-performance batteries in military and industrial sectors.

The Department of Defense stated that the loan will prioritize applications such as military drones, autonomous vehicles, robotics, and AI data centers. Sila CEO Gene Berdichevsky noted that the new battery cell plant will focus on "high-performance, high-reliability" specialty applications to meet the rigorous performance requirements of military and industrial sectors.

Silicon Anode Technology Breakthrough: 20% Range Increase and 10-Minute Fast Charging

Sila was co-founded in 2011 by former Tesla battery system architect Gene Berdichevsky and former Tesla battery supply chain director Kurt Kelty, focusing on the development of silicon-carbon anode materials. The company claims its Titan Silicon powder can directly replace traditional graphite anodes, increasing electric vehicle (EV) range by up to 20% in the same battery size while enabling 10-minute fast charging.

Compared to traditional graphite anodes, silicon offers higher energy density, and the US domestic supply chain is not subject to China’s graphite monopoly, making it a key technology of interest for the Department of Defense. Sila states that silicon anode technology is not only applicable to EVs but also widely usable in consumer electronics, drones, electric vertical takeoff and landing (eVTOL) aircraft, and robotics.

The US Army has been actively promoting the use of unmanned systems for logistics resupply and operations in hazardous areas to reduce personnel casualties. A military program involving EV startup Harbinger employs an extended-range platform that uses an onboard fuel tank to recharge batteries, demonstrating that military demand for high-performance batteries extends beyond purely electric solutions.

Moses Lake Facility Operational with Capacity to Supply 500,000 EVs

Sila officially launched its production base in Moses Lake in 2025, with an initial capacity of 2 gigawatt-hours (GWh) and plans to expand to 250 GWh within five years. The company states that the Moses Lake facility is the first automotive-scale silicon anode production plant in the US, with initial capacity planned to supply anode materials for 500,000 EVs and 500 million smartphones.

However, Sila remains in the supply chain engagement phase and has not disclosed details of formal partnerships with automakers or battery manufacturers. The company obtained ISO 9001 quality management certification in 2022, laying the foundation for entering the global automotive and electronics industries. Additionally, Sila faces allegations of overseas patent infringement but has not provided specific details on the progress of these cases.

Department of Energy and Private Equity Funds Provide Successive Investments Totaling Nearly $2 Billion

Prior to the Department of Defense loan, Sila had secured multiple rounds of investment from the US Department of Energy and private equity funds. In 2021, the Department of Energy’s ARPA-E program provided $10 million in R&D funding to reduce silicon anode production costs and improve efficiency. In 2022, an additional $100 million was allocated through the SCALEUP program to support Sila’s mass production efforts.

The private equity market has also shown strong confidence in Sila’s potential. In 2024, the company completed a $375 million Series G funding round, with investors including Atreides Management and Sutter Hill Ventures. In June of this year, Sila raised another $300 million for production and R&D expansion. To date, Sila’s total funding has reached nearly $2 billion.

While Sila emphasizes the applicability of its technology to the EV market, the Department of Defense’s loan announcement did not directly mention EV applications, indicating that military and industrial sectors will receive priority resource allocation. The Department of Defense stated that Sila’s high-performance battery technology will enhance the autonomy and reliability of US military equipment while reducing dependence on overseas supply chains.
