Chinese researchers have successfully developed the country's first carbon-14 nuclear battery, named "Zhulong." This innovation, a collaboration between Northwest Normal University and Wuxi Beita Pharmatech, utilizes a silicon-carbide semiconductor to convert energy from the decay of carbon-14 into electricity. The battery boasts a half-life of 5,730 years, promising a long operational lifespan—potentially lasting for centuries—ideal for applications in polar and deep-sea exploration, as well as aircraft and spacecraft. It produces low emissions, has achieved an energy conversion efficiency of eight percent, and can withstand extreme temperatures. Future iterations, including a second-generation model "Zhulong 2," are currently in development with testing expected to begin by the end of the year.
