Military Drone Battery Demand Surges Amid Supply Chain Concerns

• •Drones accounted for 39% of defense battery demand in 2025.
• •The U.S. is moving towards domestic battery manufacturing to reduce reliance on China.
• •Demand for drone batteries has surged since 2020, driven by geopolitical instability.

In 2025, defense applications consumed 4.34 GWh of battery power, with drones accounting for nearly 40% of this demand. The rapid growth in drone warfare, particularly following Russia's invasion of Ukraine, has highlighted the need for resilient battery supply chains. The U.S. Department of Defense is prioritizing domestic and alternative battery manufacturing to reduce reliance on Chinese supply chains. The military battery market remains small compared to the commercial sector, which is two to three orders of magnitude larger. Benchmark Mineral Intelligence reports that the demand for drone batteries has increased significantly, rising from 15% in 2020 to 39% in 2025. The ongoing instability in various regions has further emphasized the importance of battery-dependent applications in modern warfare. Efforts are underway to establish a strategic battery reserve and support domestic manufacturing capabilities.
