A layered battery having a nuclear-cored energy source. The layered battery is created by spraying P and N layers on a plurality of nuclear-cored energy producing spheres that are in the form of a powder. The spraying of the P and N layers forms a sheet of material having a P layer and an N layer that is used as a battery. This sheet is then disposed within a casing having a first and second end. The P layer is connected to the first end of the case forming an anode and the N layer is connected to the second end of the case forming an electrode. Thus a disposable sized battery is formed that has a nuclear cored energy source.
