1. A method of manufacturing a nuclear battery, the method comprising:
inserting a radiation source material into a cavity defined within a first component to form a radiation source layer, the first component comprising:
a first electrical insulator layer defining the cavity; and
a first casing layer disposed over the first electrical insulator layer;
contacting the first casing layer with a second casing layer of a second component to form an assembly, the second component comprising:
a second electrical insulator layer; and
the second casing layer disposed in contact with the second electrical insulator layer; and
swaging the assembly to form the nuclear battery.
