Description

technical field [0001] The invention belongs to the fields of osmotic power generation, chemical batteries and isotope batteries, and in particular relates to a radiation ionization-ion permeation high-performance composite isotope battery and a preparation method thereof. Background technique [0002] The isotopes whose nuclear composition (or energy state) changes spontaneously and emit radiation are called radioactive isotopes. Radioactive isotope batteries, referred to as isotope batteries, use energy-transducing devices to convert the energy of radiation released by radioactive isotopes into electrical energy output, so as to achieve the purpose of power supply. Due to the advantages of long service life, strong environmental adaptability, good working stability, no maintenance, and miniaturization, isotope batteries have been widely used in important fields such as military defense, deep space and deep sea, polar exploration, biomedicine, and electronics industry. . ...

AI Technical Summary

Problems solved by technology

[0004] The research results of the above four types of isotope batteries show that the low energy conversion efficiency is still the common feature of current isotope batteries

The development of static thermoelectric isotope batteries mainly benefits from the research and development at the national level, especially the design and manufacture of radioisotope thermoelectric generators (RTG) in the United States. The energy conversion efficiency is low, even the latest NASA report enhanced multi-mission radioisotope thermoelectric generators (eMMRTG) has a conversion efficiency of less than 10% (http: / / www.jpl.nasa.gov / news / news.php?feature=6646), so its scope of use is limited and the process of civilian use is relatively difficult

The radiant volt effect isotope battery uses semiconductor materials as energy conversion units, which can realize the miniaturization of isotope battery devices and improve its application in MEMS / NEMS and low-power electronic devices. With the rapid development of wide-bandgap semiconductors and multi-dimensional structure materials The development has achieved certain research results, but the radiovoltaic effect isotope battery has the problem of semiconductor material performance degradation under long-term radiation, which reduces the service life of the radiovoltaic effect isotope battery
