Obnews Tech Desk: Researchers at the University of Bristol have developed the world's first nuclear power battery, capable of lasting for thousands of years. This battery can bring a big revolution in the field of energy production. According to reports, a radioactive isotope called carbon-14 has been used in it, which has a half-life of 5,730 years. This battery generates electricity by embedding carbon-14 in a diamond-based structure.
Why is this battery different from traditional batteries?
Unlike conventional energy sources, this battery requires no movement or maintenance. In this, high-speed electrons emitted from radioactive decay are converted into energy. Additionally, its synthetic diamond structure captures radiation as solar cells convert photons into electricity.
Working of Nuclear-Diamond Battery
Carbon-14 emits short-range radiation, which is safely controlled within the diamond casing. This radiation does not spread to the external environment of the battery, making it completely safe for use. According to Professor Neil Fox of the University of Bristol, “Diamond is the hardest substance on earth and no other substance offers more protection than it.”

Carbon-14: Unique source of energy
The carbon-14 used in this battery is obtained from graphite blocks of nuclear reactors, where it collects on the surface. One gram of carbon-14 produces about 15 joules of energy per day. While normal AA batteries provide more energy initially, they drain quickly. In contrast, nuclear-diamond batteries have a lifetime of thousands of years.
