Coin-sized nuclear 3V battery with 50-year lifespan enters mass production

Betavolt, a Chinese company, has started mass-producing the BV100, a coin-sized nuclear battery lasting up to 50 years without charging. Using radioactive nickel-63 decay, it offers higher energy density and durability than conventional batteries. Betavolt plans a more powerful version later this year, with applications in electronics, drones, and medical devices. This innovation has sparked global interest in nuclear battery development.
