The era of charging devices daily may soon become obsolete, as a Chinese firm introduces a miniature nuclear battery designed to deliver uninterrupted power for decades.
In a significant technological breakthrough, Beijing Betavolt New Energy Technology Company Ltd has unveiled an advanced atomic battery capable of generating electricity for up to 50 years without replacement, marking a potential turning point in modern energy solutions.
The company’s prototype, known as the BV100, is built using a Nickel-63 radioactive isotope combined with a diamond semiconductor, enabling the conversion of radioactive decay into a stable and long-lasting electrical output.
Unlike earlier nuclear batteries developed in the mid-20th century often criticised for being bulky, hazardous, and reliant on materials such as plutonium Betavolt claims its innovation is compact, safe, and suitable for contemporary applications. The battery is designed to remain stable even under extreme physical conditions and is not expected to leak harmful radiation.
The BV100’s structure involves placing a microscopic layer of Nickel-63 between ultra-thin diamond semiconductor converters, supported by the company’s proprietary single-crystal diamond technology, which it claims is unmatched globally.
Measuring just 15 x 15 x 5 millimetres, the battery is remarkably small, though it currently delivers 100 microwatts at 3 volts, limiting its use to low-power applications. However, multiple units can be combined to increase output, and Betavolt is already working on a more powerful 1-watt version expected by 2025.
The technology holds promise for a wide range of sectors including artificial intelligence, aerospace, medical devices, MEMS systems, intelligent sensors, robotics, and drones. In the long term, it could enable the development of consumer electronics including smartphones that may no longer require regular charging.
According to the company, the battery uses Nickel-63, which gradually decays into stable copper, ensuring both safety and environmental stability. It can operate effectively in extreme temperatures ranging from -60°C to 120°C, and is designed to remain secure even if subjected to puncture or physical damage.
The breakthrough comes amid increasing global interest in long-life energy solutions. In the United States, Infinity Power, supported by the Department of Defense, is also developing nuclear battery technology, with claims of a compact device capable of producing power for over 100 years.
Although still in its early stages, Betavolt’s innovation signals a potential paradigm shift in energy technology. The company is exploring advanced.
