Researchers in China have developed a nuclear battery using the carbon-14 isotope. The breakthrough was achieved jointly by scientists at Northwest Normal University in Lanzhou, the capital of Gansu Province, and a private nuclear medicine company in Jiangsu Province, WuXi Beta PharmaTech. The battery, named Chulong-1, can operate across an extremely wide temperature range—from very cold to very hot—and is capable of storing ten times more energy than conventional lithium-ion batteries. It can generate electricity continuously for around 100 years, making it particularly suitable for locations requiring long-term power supply, such as polar regions, deep-sea environments, or spacecraft.
