| Abstract： | Nuclear batteries, with their advantages of high power density, reliability and long lifespan, have been widely applied in fields such as aerospace and polar exploration. In this paper, the earliest and most technologically mature radioisotope thermoelectric generator (RTG) utilized for the Seebeck effect is introduced. It provides a systematic analysis and introduction from aspects including radioactive nuclides, thermal source structure, shielding layer and insulation layer, thermoelectric conversion module, and heat dissipation device. Finally, the advantages of RTG in space and civilian applications are briefly analyzed and compared with traditional energy batteries. The advantages and disadvantages of RTG are summarized. The future prospects for these batteries are also briefly discussed. |
