A groundbreaking innovation from the University of Bristol and the UK Atomic Energy Authority (UKAEA) has led to the creation of the worldโs first carbon-14 diamond battery, a power source with the potential to last thousands of years.
This revolutionary battery harnesses the radioactive isotope carbon-14โwidely known for its use in radiocarbon datingโto produce a diamond-structured power source. Its longevity and durability open up game-changing applications across diverse fields.
Applications That Redefine Energy Use
- Medical Marvels: The bio-compatible diamond battery is a perfect fit for medical devices such as ocular implants, hearing aids, and pacemakers. Its extended lifespan minimizes replacements, reducing patient discomfort and improving quality of life.
- Extreme Environments: Designed to thrive where traditional batteries fail, these durable power sources can operate in space or harsh Earth conditions. From spacecraft to payload tracking, their ability to provide power for decades ensures lower costs and extended operational lifespans.
- Advanced Tracking and Security: Ideal for active RF tags, these batteries could track and identify devices across industries, offering a robust solution for long-term use in critical security and aerospace operations.
Professor Tom Scott, a leading expert in materials at the University of Bristol, highlighted the transformative potential of this innovation:
“Our micropower technology can support a whole range of important applications, from space technologies and security devices to medical implants. Weโre excited to explore these possibilities alongside industry and research partners in the coming years.”
How It Works
The carbon-14 diamond battery operates by capturing the energy released during the radioactive decay of carbon-14, which has an impressive half-life of 5,700 years. Similar to how solar panels convert photons into electricity, these batteries use fast-moving electrons from the diamondโs structure to generate low levels of continuous power.
Sarah Clark, Director of Tritium Fuel Cycle at UKAEA, emphasized the safety and sustainability of the technology:
“Diamond batteries offer a safe, sustainable way to provide continuous microwatt levels of power. Using a manufactured diamond to encase carbon-14, they ensure safety while delivering reliable energy.”
The Road to Innovation
This achievement was made possible through a collaborative effort at UKAEAโs Culham Campus, where scientists and engineers developed a specialized plasma deposition rig to grow the diamond material. The project also leverages UKAEAโs extensive experience in fusion energy, accelerating advancements in related technologies.
As the possibilities for carbon-14 diamond batteries expand, this pioneering technology holds the promise of reshaping the future of energyโproviding safe, sustainable power for generations to come.
