A coin-sized nuclear battery that lasts 50 years promises to revolutionize technology
Betavolt, a young Chinese company, has developed the BV100, a nuclear battery that can operate for 50 years without maintenance or recharging. This device uses a combination of nickel-63 and diamond semiconductors to generate constant power, ideal for low-power applications such as medical implants and IoT sensors. With a compact size and ability to operate in extreme conditions, this technology could revolutionize how we power devices in critical sectors. Are we facing the future of portable energy?
The core of the bv100: diamond and nickel
The BV100 employs innovative technology based on the radioactive isotope nickel-63, a material that disintegrates by releasing electrons, and diamond semiconductors that convert that energy into electricity. This compact design, measuring just 15 x 15 x 5 mm, is smaller than a euro coin and weighs just a few grams.
The battery can generate 100 microwatts at a constant voltage of 3V, enough to power low-power devices for decades. Additionally, the BV100 operates efficiently in a temperature range of -60°C to 120°C, making it suitable for extreme environments. Its modular design even allows for increased energy capacity by combining multiple units, opening the door to more demanding applications in the future.
