Scientists and engineers from the UK Atomic Energy Authority (UKAEA) and the University of Bristol have successfully created the world’s first carbon-14 diamond battery.
This new type of battery has the potential to power devices for thousands of years, making it an incredibly long-lasting energy source.
The battery leverages the radioactive isotope, carbon-14, known for its use in radiocarbon dating, to produce a diamond battery.
Several game-changing applications are possible. Bio-compatible diamond batteries can be used in medical devices like ocular implants, hearing aids, and pacemakers, minimising the need for replacements and distress to patients.
Diamond batteries could also be used in extreme environments – both in space and on earth – where it is not practical to replace conventional batteries.
The batteries could power active radio frequency (RF) tags where there is a need to identify and track devices either on earth or in space, such as spacecraft or payloads, for decades at a time, thus reducing costs and extending operational lifespan.
The carbon-14 diamond battery works by using the radioactive decay of carbon-14, which has a half-life of 5,700 years, to generate low levels of power.
It functions similarly to solar panels, which convert light into electricity, but instead of using light particles (photons), they capture fast-moving electrons from within the diamond structure.
A team of scientists and engineers from both organisations worked together to build a plasma deposition rig, a specialised apparatus used for growing the diamond at UKAEA’s Culham Campus. ■
