In a groundbreaking technological leap, China has unveiled a nuclear-powered batterythat can last for up to 50 years without ever needing to be charged. Roughly the size of a coin, this battery could redefine how we power devices forever.
Developed by Beijing-based firm Betavolt Technology, the battery uses radioactive isotopes that decay slowly, releasing energy continuously over decades. It’s the first of its kind to integrate nuclear energy safely inside a miniature battery cell.
Unlike traditional lithium-ion batteries that degrade and require recharging, this nuclear microbattery generates electricity through beta decay, a process where isotopes emit electrons that are converted into usable power.
The energy source inside — Nickel-63 — is stable and shielded by multiple protective layers, ensuring no radiation escapes. Engineers emphasize it’s completely safe for consumer electronics, even medical implants.
What makes it extraordinary is its longevity and stability. The battery can endure extreme temperatures ranging from -60°C to +120°C, making it perfect for space missions, AI sensors, and defense systems where maintenance isn’t possible.
Betavolt claims this nuclear battery can provide 100 microwatts of power from a volume smaller than a coin. It’s scalable — meaning multiple cells can be stacked together to power larger systems like drones or satellites.
The potential applications are limitless. Imagine smartphones that never need charging, pacemakers that last a lifetime, or space probes powered indefinitely without sunlight or fuel.
Nuclear batteries aren’t new, but earlier designs were bulky and unsafe. China’s innovation marks a turning point — achieving miniaturization, safety, and efficiency in a single design.
According to scientists, the battery’s structure isolates radiation with layers of diamond and semiconductor materials, ensuring it’s environmentally friendly after disposal. After 50 years, it simply becomes inactive and recyclable.
China’s announcement has reignited global interest in nuclear microenergy, especially as the world seeks sustainable alternatives to chemical batteries that harm the environment and rely on rare metals.
Experts say this technology could soon power IoT devices, satellites, deep-sea sensors, and even Mars rovers, offering consistent power where recharging is impossible.
Betavolt’s engineers are already working on higher-capacity versions that could power laptops, drones, and autonomous vehicles within the next decade.
The innovation not only reflects China’s dominance in next-generation energy research but also highlights how nuclear science can be repurposed for peaceful, sustainable technologies.
As one researcher put it — “This battery doesn’t just store power; it creates it — quietly, safely, and endlessly.”
If successful, China’s nuclear battery could revolutionize the energy landscape, marking the beginning of a new era in portable power — one where charging cables, battery swaps, and power banks become history.
