World’s first carbon-14 diamond battery could last 5,700 years – no recharging needed!
Britain has unleashed the world’s first carbon-14 diamond battery that could last 5,700 years without recharge, revolutionising healthcare and technology.
A battery to last thousands of years? UK scientists have achieved an earth-shattering innovation – the creation of a diamond-powered battery that could keep running for millennia without ever needing a recharge.
Power that lasts for thousands of years
In a pioneering collaboration, experts from the UK Atomic Energy Authority (UKAEA) and the University of Bristol have unveiled the world’s first carbon-14 diamond battery. This revolutionary power source transforms the radioactive decay of carbon-14 – famously used in radiocarbon dating – into a sustainable energy supply capable of powering devices for thousands of years.
Transforming technology across industries
The possible uses for this diamond-powered innovation are staggering. In medicine, the bio-compatible batteries could fuel ocular implants, pacemakers, and hearing aids, reducing the need for replacements and sparing patients unnecessary discomfort.
Beyond healthcare, the robust design means these batteries can thrive in extreme environments, from the icy void of space to radioactive hotspots on Earth. They could power active radio frequency tags for tracking spacecraft or equipment for decades at a time, cutting costs and boosting operational lifespans.
“Diamond batteries offer a safe, sustainable way to provide continuous microwatt levels of power,” said Sarah Clark, Director of Tritium Fuel Cycle at UKAEA. “They are an emerging technology that uses a manufactured diamond to safely encase small amounts of carbon-14.”
How it works: Diamonds powered by decay
The secret behind this near-eternal power lies in carbon-14’s radioactive decay, which has a half-life of 5,700 years. Much like a solar panel harnesses sunlight, the battery converts energy from fast-moving electrons released during radioactive decay into electricity.
“Diamond batteries are a fascinating innovation,” said Professor Tom Scott, Professor in Materials at the University of Bristol. “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.”
Made to last at Culham
The project wasn’t just pie in the sky; it was built in the lab. The team at UKAEA’s Culham Campus constructed a plasma deposition rig – a high-tech machine that grows synthetic diamond layers – to bring their vision to life. This innovative work has its roots in the UKAEA’s fusion energy research, demonstrating how the pursuit of cleaner energy solutions is driving technological breakthroughs across industries.
The future is bright
With its potential to eliminate battery replacements and extend lifespans in critical systems, the carbon-14 diamond battery may just change how we power the world. While it’s not ready to light up your smartphone just yet, many are arguing that it’s the future of energy.
