Researchers from Northwest Normal University and Gansu Zhulong Technology developed a new-generation carbon-14 nuclear battery with a microwatt output [1].
The achievement represents a shift toward energy independence for long-life power sources. By eliminating reliance on foreign components, the team has created a sustainable pathway for powering devices that must operate for decades without maintenance.
The project was completed on Monday by a cross-sector team in China [1]. The researchers said the new device far surpasses its predecessor and marks a major step in long-life power sources [2].
Central to the breakthrough is the use of carbon-14, a radioactive isotope that provides a steady stream of energy over an extended period. The team achieved a microwatt output [1], a technical milestone that allows the battery to support low-power electronics more effectively than previous iterations [2].
The development team said the device was developed without foreign tech or parts [2]. This self-reliance ensures that the production and scaling of the batteries are not subject to international supply chain disruptions or export restrictions.
The battery is designed for applications where replacing traditional batteries is impossible or impractical. This includes deep-sea sensors, space probes, and medical implants, devices that require consistent, low-level power for years or even decades.
Researchers said the project demonstrates the ability to integrate nuclear physics with materials science to produce a viable commercial power source [2]. The team focused on optimizing the energy conversion process to ensure the microwatt output remained stable [1].
“The device, which marks significant step in long-life power sources, was developed without foreign tech or parts.”
The development of a self-reliant nuclear battery reduces China's dependence on global semiconductor and specialty material chains for critical infrastructure. By achieving a stable microwatt output using carbon-14, the researchers have moved closer to commercializing 'forever batteries' for extreme environments, potentially granting a strategic advantage in aerospace and deep-sea exploration.
