Scientists and engineers produce world's first carbon-14 diamond battery with potential lifespan of thousands of years
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.
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. UKAEA’s approach is to hold this hot plasma using strong magnets in a ring-shaped machine called a ‘tokamak’, and then to harness this heat to produce electricity in a similar way to existing power stations.
