Radioisotope batteries are devices that produce electrical energy by converting the heat generated from the radioactive decay of isotopes. These batteries are primarily utilized in long-duration, low-maintenance applications, including space missions, remote sensing technologies, and medical implants.
Key types of radioisotope batteries include plutonium-238, strontium-90, cobalt-60, and promethium-147 batteries. Plutonium-238 batteries, which utilize thermoelectric generators to transform decay heat into electricity, are particularly suitable for space exploration due to their long operational life. These batteries are offered in multiple configurations, such as thin-film, solid-state, microbatteries, and packaged battery formats. They find use in various sectors such as space exploration, medical equipment, defense, consumer gadgets, and industrial systems, serving end-users in aerospace, healthcare, defense, telecommunications, and industrial sectors.
Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.
The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.

These radioisotope battery market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.
The radioisotope battery market size has grown rapidly in recent years. It will grow from $0.42 billion in 2024 to $0.47 billion in 2025 at a compound annual growth rate (CAGR) of 10.6%. The historical market expansion was driven by missions in space exploration, the need for durable power supplies in isolated settings, military and defense sector applications, rising demand for deep-sea and Arctic exploration tools, and the reliability of these power sources in harsh environments.
The radioisotope battery market size is expected to see rapid growth in the next few years. It will grow to $0.69 billion in 2029 at a compound annual growth rate (CAGR) of 10.4%. This anticipated growth is fueled by the development of space-based technologies, an increasing requirement for miniature power solutions in medical devices, broader use in autonomous systems, a focus on clean and low-maintenance energy sources, and enhanced funding in nuclear energy research. Emerging trends expected during the forecast period include the creation of compact radioisotope batteries, wider application in remote monitoring and IoT, exploration of alternative isotopes, downsizing for wearable technology, and collaborations between space organizations and private enterprises.
The increasing number of space exploration missions is expected to propel the growth of the radioisotope battery market going forward. Space exploration missions are scientific or exploratory journeys conducted beyond Earth's atmosphere to study celestial bodies, space environments, and the potential for life or human habitation. The increasing number of space exploration missions is primarily driven by advancements in aerospace technology, which have improved the reliability, cost-efficiency, and capability of launch vehicles, spacecraft, and satellite systems. Radioisotope battery supports space exploration missions by providing a long-lasting and reliable power source for spacecraft and instruments operating in environments where solar energy is insufficient or unavailable. For instance, in September 2022, according to the Government Accountability Office, a US-based government agency, there were nearly 5,500 active satellites in orbit, with projections indicating that around 58,000 more could be launched by 2030. Therefore, the increasing demand for space exploration missions is driving the growth of the radioisotope battery market.
Leading players in the radioisotope battery market are increasingly focusing on developing micro-scale, long-duration energy sources to support compact equipment operating in remote or extreme settings. These micro-scale batteries are engineered to function reliably for several years or even decades without replacement or charging, making them highly suitable for medical devices, instruments used in space, and remote monitoring systems. A notable example is the January 2024 launch of the BV100 by Beijing Betavolt New Energy Technology Company Ltd., a new energy firm based in China. The BV100 is the first mass-produced nuclear battery to use the radioisotope nickel-63. This 3V nuclear battery integrates nickel-63 with a diamond semiconductor for energy conversion and is designed to offer continuous power for up to 50 years. It is specifically created for compact and mission-critical applications, such as medical implants, space instruments, and hard-to-reach sensors, where maintenance is difficult or impractical.
In February 2025, Nusano Inc., a U.S.-based advanced radioisotope production company, entered into a collaboration with Atomiq Inc. to jointly develop and scale technologies for nuclear diamond batteries. This strategic alliance seeks to merge Nusano's capabilities in isotope production with Atomiq's expertise in battery innovation to advance manufacturing infrastructure and deployment. Atomiq Inc., headquartered in the U.S., is engaged in creating high-efficiency radioisotope batteries that transform radioactive decay energy into stable, long-duration electrical output without requiring recharging.
