A manufacturing process of a nuclear cored battery having steps of processing a nuclear core, and creating a ceramic phosphor slurry material and combining them to form a homogenous mixture. The homogeneous mixture is then placed into a spray dryer in order to create a nuclear core surrounded by a temporary bound layer of mixed ceramics and then undergoes a high temperature manufacturing process wherein structural defects are added to create a light dissipating material. The light dissipating material is then coated with a photovoltaic material to create a spherical energy source that is in the form of a powder. This powder is then introduced into a P and N layer.
