核电池材料及核电池的应用

核电池具有体积小、寿命长、不受外界环境影响等优点,因而在航空航天、深海、极地、心脏起搏器、微型电机等领域得到广泛地应用。核电池的发展与所用材料的发展互相促进。从同位素放射源、电能转换、密封保护的角度介绍了核电池所用材料的发展和最新研究进展,同时也介绍了核电池现有和潜在的应用领域。Nuclear battery has lots of advantages such as small volume, longevity, environal stability and so on, therefore, it was widely used in aerospace, deep-sea , polar region, heart pacemaker, micro-electromotor and other fields etc. The application of nuclear battery and the development of its materials promote each other. In this paper the development and the latest research progress of nuclear battery materials has been introduced from the view of radioisotope, electric energy conversion and encapsulation. And the current and potential applications of the nuclear battery are also summarized.
