Researchers at the UK Atomic Energy Authority (UKAEA) and the University of Bristol have developed a groundbreaking carbon-14 diamond battery, offering a potential energy source that could last thousands of years. This innovation leverages the radioactive isotope carbon-14, commonly used in radiocarbon dating, to generate electricity.

Revolutionary energy technology

The diamond battery's design incorporates a man-made diamond structure that safely encases carbon-14. The process involves capturing high-energy electrons released during the radioactive decay of the isotope to generate a steady power output. Unlike conventional batteries, this technology mimics the operation of solar panels, but instead of relying on light, it harnesses radiation from within the diamond.

Potential applications

The versatility of this technology opens doors to multiple uses. Bio-compatible versions of the battery could revolutionise medical devices, powering implants such as pacemakers and hearing aids for an entire lifetime without requiring replacement. Additionally, the batteries' ability to operate in extreme conditions makes them a prime candidate for applications in space exploration, enabling decades-long missions without the logistical challenges of battery replacement.

On Earth, they can be used in harsh environments to power devices such as radio frequency tags, which are essential for tracking equipment and spacecraft. These batteries promise to reduce operational costs and increase the longevity of devices in remote or hostile locations.
