Description

Technical field [0001] The present invention relates to a thermonuclear battery, in particular to a radioactive source that uses strontium-90 or tritium as a radioactive source. The radioactive source continuously emits energy-carrying rays with electric and thermal energy during the decay process through a semiconductor energy conversion device, and allows the energy to A device that converts and collects electrical energy. Background technique [0002] Nuclear battery, also known as isotope battery, is a device that uses radioisotope decay to release energy-carrying particles (such as alpha particles, beta particles and gamma particles) and convert their energy into electrical energy. According to the voltage level provided, nuclear batteries can be divided into high-voltage type (a few hundred to several thousand V) and low-voltage type (about tens of mV to 1V). [0003] Substantial progress in nuclear batteries began in the 1950s. Because of their small size, light weight and ...
