Betavolt builds BV100 nickel-63 nuclear battery lasting 50 years
Technology
A Chinese company, Betavolt, has built a tiny nuclear battery called BV100 that can power devices for up to 50 years straight: no recharging or replacing required.
It runs on nickel-63 isotope decay and is designed for things like medical implants and environmental sensors that need steady, reliable energy.
BV100 coin-sized battery 100 microwatts 3V
The BV100 is super compact (about the size of a coin) and delivers 100 microwatts at 3 volts. You can even combine units for more power if needed.
Betavolt chose nickel-63 because it turns into harmless copper as it decays, so there is low radiation risk, making this battery safe for sensitive tech.
