Researchers from the University of Bristol, in partnership with the UK Atomic Energy Authority, have presented an innovation that could transform the world of energy: a new battery that lasts more than 5,000 years. The secret of this technology lies in the use of radioactive carbon in diamond, creating a practically infinite and extremely safe source of energy.
The new battery uses carbon-14, a radioactive isotope famous for its half-life of 5,700 years, widely used in archaeological dating. During its beta decay process, carbon-14 releases a small but constant amount of electrons, generating energy. To ensure safety and efficiency, the researchers encapsulated the material in artificial diamonds, created by a specialized plasma process. This protection ensures that the battery is sustainable and suitable for a range of long-lasting applications.
Promising And Practical Applications

Thanks to the use of radioactive carbon in diamond, the new battery is ideal for scenarios where battery replacements would be impractical or impossible. Here are some of the possible applications:
Medical Implants: devices like pacemakers and hearing aids could function for decades without needing replacement, eliminating frequent surgeries.
-
A 400-meter colossus powered by natural gas has just set sail from Shanghai to Europe, carrying over 24,000 containers. It is the world’s largest dual-fuel container ship and can cross the planet without refueling even once.
-
A new study overturns the central idea we learned about planets and suggests that Earth is the exception rather than the rule; most rocky worlds in the galaxy may not have a core or mantle, just a single turbulent fluid extending to the center.
-
Scientists reanimated a 48,500-year-old virus in the laboratory that had been frozen in the Siberian permafrost since before the extinction of the Neanderthals, and it was still capable of infecting living organisms after tens of millennia dormant in the ice.
-
The oldest nuclear aircraft carrier still in operation in the world is currently on Brazilian soil making its final journey before retirement, and two American military planes landed in Salvador and Fortaleza to support the mission.
Space and Underwater Exploration: space probes, sensors in deep waters, and other equipment could operate for centuries, even in extreme conditions.
Tracking and Monitoring: tags on satellites and space debris will remain active for decades, revolutionizing monitoring systems.
According to Sarah Clark from the UKAEA, “diamond batteries offer a safe and sustainable way to provide continuous levels of microwatts of power,” highlighting the versatility and safety of radioactive carbon in diamond.
A Promising Future For The New Battery
Although the commercial viability of the new battery still needs to be explored, researchers believe it could be a game-changer in various industries, from medical technology to space exploration. Professor Tom Scott from the University of Bristol states that the team is eager to work with industry partners to expand the possibilities of this technology.
This innovation not only redefines the concept of durable batteries but also signals a revolution in energy storage. With the use of radioactive carbon in diamond, humanity is taking an important step towards a more sustainable and technologically advanced future.
