Scientists from the University of Bristol and the UK Atomic Energy Authority (UKAEA) have developed the world’s first carbon-14 diamond battery, capable of providing power for thousands of years. It functions similarly to solar panels, which convert light into electricity, but instead of using light particles (photons), it captures fast-moving electrons from within the diamond structure. The device harnesses the radioactive decay of carbon-14, encased within a manufactured diamond, to generate electricity. “Diamond batteries offer a safe, sustainable way to provide continuous microwatt levels of power,” stated Sarah Clark, UKAEA Director of Tritium Fuel Cycle.

With a half-life of 5,700 years, the battery could revolutionize power sources for medical implants, space missions, and remote applications. “Our micropower technology can support a whole range of important applications,” stated Professor Tom Scott of the University of Bristol. If commercialized, the battery could eliminate the need for replacements in critical devices like pacemakers and long-duration spacecraft such as Voyager 1. Researchers aim to explore industrial partnerships to advance this innovation, potentially reshaping how electronics are powered in extreme environments.Scientists from the University of Bristol and the UK Atomic Energy Authority (UKAEA) have developed the world’s first carbon-14 diamond battery, capable of providing power for thousands of years.
