Summary: I’m reasonably sure that my readers first question is: “What the heck are nuclear batteries?" First of all, it’s a misnomer. Although they do use nuclear radioisotopes, they are not batteries, as they cannot be charged nor discharged. They are energy converters and are related to other energy converters like photovoltaic (PV) cells (which convert sunlight to electricity) and thermoelectric converters (which convert heat, that is temperature differences, to electricity). In fact, some “nuclear batteries” use these other two converters (and similar devices) in their design. Nuclear batteries convert nuclear radiation to electricity.
