nuclear batteries
Decay-powered energy sources
Nuclear batteries convert energy from radioactive decay into electricity.
Unlike nuclear reactors, they don't use fission chain reactions—they harvest particles or heat emitted as unstable atoms decay.
They produce small amounts of power but last decades without refueling, making them ideal for spacecraft, pacemakers, and remote sensors.
Also called radioisotope generators or atomic batteries.
