What is the use of Nuclear Battery | Nano Diamond Battery | Tech Baba

Like nuclear reactors, the nuclear battery generates electricity from radiation energy but differs from them as they do not use a chain reaction. These batteries generate electricity from the Beta decay of the radioactive isotopes that emit beta particles from them. In this video, we have covered the details about
How do these Beta-decay batteries work?
What are Nanodiamond batteries? And applications of this technology.
