Japan Unveils First Uranium-Based Rechargeable Battery
The world’s first uranium-based rechargeable battery was created by Japan, marking a significant breakthrough in nuclear energy and providing a potential way to reuse enormous radioactive waste stockpiles. This ground-breaking technology, developed by the Japan Atomic Energy Agency (JAEA), has the potential to revolutionize the use of depleted uranium and support the storage of excess electricity from renewable sources.
How the Uranium Battery Works
The research team successfully demonstrated the charging and discharging performance of a battery that uses uranium as an active material to trigger chemical reactions and generate electricity. The uranium used in the experiment had the same chemical properties as depleted uranium, a byproduct of uranium enrichment that is currently unsuitable for conventional nuclear reactors.
By utilizing uranium in battery technology, researchers are exploring a new resource value for depleted uranium, turning nuclear waste into an energy storage solution.

Features of the Uranium Battery
- Compact Design: The prototype measures 10 cm wide and 5 cm tall.
- Electrolyte Composition: It uses a uranium-containing electrolyte for the negative electrode and an iron-containing electrolyte for the positive electrode.
- Voltage Output: The battery generates 1.3V, close to a standard alkaline battery’s 1.5V.
- Stability and Durability: It successfully underwent 10 charge-discharge cycles with minimal performance degradation, proving its stability and efficiency.
Future Potential and Applications
The uranium-based battery could revolutionize energy storage by providing an alternative use for depleted uranium. Additionally, its ability to store surplus electricity from renewable sources makes it a promising technology for the transition to clean energy solutions.
With further development, uranium batteries may become a sustainable option for long-term energy storage, reducing nuclear waste while enhancing global energy security.
Japan’s latest nuclear innovation marks a major step forward in harnessing radioactive materials for energy storage. If successfully commercialized, uranium-based batteries could reshape the future of nuclear waste management and renewable energy storage, contributing to a more sustainable and efficient power grid.
