Foreign Media: Northwest Normal University and Gansu Zhulong Technology Company jointly launched the new generation carbon-14 nuclear battery "Qianji Yuantian Shu" (Thousand Machine Origin TianShu), achieving full domestic production without using any foreign technology or components.
This battery represents a significant upgrade over the "Zhulong No. 1" prototype released in November 2024: the amount of radioactive material has been reduced to 22%, short-circuit current increased by 2.5 times, maximum power output boosted to 2.6 times, effective volume reduced to 17%, volumetric power density improved by 15.5 times, while voltage and stability remain unchanged.
Carbon-14 has a half-life of 5,730 years, with a theoretical lifespan reaching thousands of years. It operates effectively within a temperature range of -100°C to 200°C, making it suitable for applications in medical implants, deep-sea and polar environments, and national defense and aerospace sectors—marking a key breakthrough in China's new energy strategy.
