Scientists have unveiled a nuclear-powered diamond battery that can deliver ultra-low, steady power for up to 5,700 years. The device uses radioactive carbon-14, encapsulated inside layers of synthetic diamond. As carbon-14 slowly decays, it releases energy that is converted into electricity—without combustion, moving parts, or emissions. Diamond acts as a radiation shield, making the battery safe for niche applications. While it won’t power cars or homes, it’s ideal for medical implants, space

Beijing-based startup Betavolt has successfully transitioned its BV100 nuclear battery from pilot testing into mass production. This marks the first time a miniature atomic battery using nickel-63 and diamond semiconductors has reached the industrial market, providing a stable 3V output for up to 50 years. The technology works by converting the energy released from decaying isotopes into electricity through a 10-micron-thick diamond semiconductor. While the current coin-sized unit delivers 100 m
