Researchers from the University of Bristol and the UK Atomic Energy Authority (UKAEA) have created the world’s first carbon-14 diamond battery that could power devices for thousands of years. They could also be used in extreme environments, both in space and right here on earth, where it just isn’t practical to replace conventional batteries.
How does a carbon-14 diamond battery work? Put simply it utilizes the radioactive decay of carbon-14, which has a half-life of roughly 5,700 years, to generate low levels of power. It functions similar to solar panels that convert light into electricity, but rather than use light particles (photons), they capture fast-moving electrons from within the diamond structure.

Our micropower technology can support a whole range of important applications from space technologies and security devices through to medical implants. We’re excited to be able to explore all of these possibilities, working with partners in industry and research, over the next few years,” said Professor Tom Scott, Professor in Materials at the University of Bristol.
