Chinese company Wuxi Beita Pharmatech<\/strong> , in collaboration with Northwest Normal University<\/strong> , has developed a prototype long-life nuclear battery. This design, named Zhulong-1<\/strong> , is a power source based on carbon-14<\/strong> ( C-14<\/em> ) and a silicon carbide<\/strong> ( SiC<\/em> ) semiconductor, allowing for continuous electricity generation. <\/p>\n\n

Long-life nuclear battery technology<\/h2>\n\n

The Zhulong-1 battery<\/strong> harnesses C-14, an isotope with a half-life of approximately 5,730 years, to emit beta particles that interact with the semiconductor, creating a reaction that generates a stable electric current.<\/p>\n\n

According to Zhang Guanghui, a specialist and technology leader for the project, the key element of the development lies in the preparation of high-activity C-14<\/strong> sources and the optimization of energy conversion efficiency. Tests conducted by the Hefei Institute of Physical Sciences<\/strong> confirmed the battery’s stability and advanced performance. <\/p>\n\n

On the other hand, one of the most impressive aspects of Zhulong-1<\/strong> is its ability to operate in extreme conditions, with a temperature range of -100 \u00b0C to 200 \u00b0C. In addition, its energy density is 10 times higher than that of lithium-ion batteries<\/a><\/strong> , with a degradation of less than 5% over 50 years<\/strong> . <\/p>\n\n

These specifications make it ideal for applications ( IoT<\/em> ), medical devices such as pacemakers and brain-computer interfaces, as well as in space exploration and extreme locations<\/strong> such as the deep ocean<\/strong> and Antarctica<\/strong> .<\/p>\n\n

The research team is working on an improved version, the Zhulong-2<\/strong> , with a focus on miniaturization and cost reduction<\/strong> . According to Cai Dinglong, project manager, the new model could be announced later this year or early next year, with a size equivalent to that of a coin. <\/p>\n\n
