Chinese startup Betavolt has created a "permanent" battery for smartphones

Chinese company Betavolt has developed a new "eternal" battery capable of generating electricity for 50 years. This is the world's first nuclear battery smaller than a coin, containing 63 nuclear isotopes.

The compact size of the battery allows it to be used in mobile phones that will never need charging or drones capable of flying indefinitely. The battery's multilayer design ensures its safety—it will not catch fire or explode under sudden force, and it can operate at temperatures ranging from -60°C to 120°C.

The next-generation battery is already undergoing pilot tests and will subsequently be mass-produced for commercial use.
