Can a phone battery last 50 years without needing to be recharged?

"A nuclear battery measuring 15 x 15 x 5mm uses 63 nuclear isotopes to generate 100 microwatts and a voltage of 3V through radioactive decay," - Techradar, a technology website, quotes a statement from the Chinese technology company Betavolt.

The battery is currently in the testing phase, and the company plans to mass-produce it for use in commercial devices such as phones and drones. It could also be applied to aerospace equipment, artificial intelligence (AI), medical devices, sensors, and micro-robots.

"This technology could revolutionize electronics by completely eliminating the need for portable chargers and creating devices that can run continuously for 50 years without power degradation," Betavolt asserts.

Not only are these nuclear batteries incredibly small, incredibly durable, and have an inexhaustible energy source, but they are also considered absolutely safe "because they do not catch fire or explode" in the event of an accident.

Amid concerns that nuclear batteries could harm users' health, Betavolt issued a reassuring statement: "Nuclear batteries are safe because they do not emit external radiation. After the battery decomposes, the 63 nuclear isotopes will turn into copper, which is non-radioactive and therefore poses no threat to health or the environment."
