The aerospace and defense battery market size is expected to see strong growth in the next few years. It will grow to $5.29 billion in 2030 at a compound annual growth rate (CAGR) of 6.7%. The growth in the forecast period can be attributed to rising adoption of sodium-ion and next-generation battery technologies, increasing need for lightweight and high-capacity energy storage, expansion of unmanned aerial vehicles and defense drones requiring advanced batteries, focus on longer lifecycle and faster recharge capabilities, integration of batteries in emerging aerospace propulsion and hybrid systems. Major trends in the forecast period include increasing demand for long-life batteries for mission-critical operations, growing adoption of lightweight battery chemistries for aerospace platforms, rising investment in battery safety and thermal management systems, expansion of battery use in hybrid aircraft propulsion and onboard systems, growing procurement of high-density batteries for unmanned defense platforms.

The rising number of space missions is expected to drive the growth of the aerospace and defense battery market. Space missions are planned operations conducted in outer space using spacecraft or satellites for purposes such as exploration, research, communication, and defense. The increase in these missions is largely attributed to advancements in reusable rocket technology, which lower launch costs and enable more frequent deployments. Aerospace and defense batteries play a critical role in supporting these missions by delivering reliable, high-density power required for spacecraft systems, communication devices, and scientific instruments in harsh space environments. For example, in November 2023, the U.S. International Trade Commission reported that space launches in 2023 were projected to reach approximately 197 by year-end, surpassing the 186 launches recorded in 2022. As a result, the growing number of space missions is boosting demand for aerospace and defense batteries.

Companies in the aerospace and defense battery market are concentrating on developing innovative technologies such as silicon anode material batteries to enhance the performance and lifespan of next-generation power systems used in advanced aircraft, drones, and defense equipment. Silicon anode material batteries replace graphite with silicon in the anode, which improves energy storage capacity and overall battery performance. For instance, in May 2025, Amprius Technologies Inc., a US-based lithium-ion battery manufacturer, introduced the SiCore 450 Wh/kg silicon-anode lithium-ion battery designed to boost energy density for aerospace and defense uses. The SiCore battery is specifically built for demanding aerospace and defense applications, including high-altitude platforms and unmanned aerial systems, functioning effectively in extreme temperatures and providing longer flight times, greater payload capacity, and reduced system weight.
