Atomic Battery (or Nuclear Battery) generates electricity through the decay of radioactive particles. Some batteries use this decay to generate heat and then harvest with thermocouples; others harness diode junctions to facilitate non-thermal conversion. The Atomic Battery has an advantage over other types of batteries due to its high energy density, about 104 times higher, and an extremely long life than a chemical battery, but is very costly. The Atomic Battery is typically used as power sources for equipment that must operate unattended for long periods of time, such as spacecraft, pacemakers, underwater systems and automated scientific stations in remote parts of the world.
