Triboluminescence isotope battery

Abstract

The invention provides a triboluminescence isotope battery. The triboluminescence isotope battery comprises a shell and a transducer arranged in the shell. The transducer comprises a cantilever beam,one end of which in the length direction is fixed to the shell, and the other end of which extends into the shell and is suspended; the first charge collection plate arranged on the lower surface of the free end of the cantilever beam; the second charge collection plate arranged on the shell and opposite to the first charge collection plate, with the polarity of charges collected by the second charge collection plate being opposite to that of charges collected by the first charge collection plate; a radioactive source arranged in the shell; a triboluminescence assembly arranged on the upper surface of the fixed end of the cantilever beam; the first photoelectric conversion assembly arranged on the upper surface of the triboluminescence assembly; the first thermoelectric conversion assemblyarranged on the upper surface of the free end of the cantilever beam; and a cooling fin arranged on the upper surface of the first thermoelectric conversion assembly. The battery has the characteristics of high energy conversion efficiency, high output power, strong environmental applicability, good working stability and long service lifetime.

Description

technical field [0001] The application belongs to the fields of triboluminescence devices, thermoelectric devices, isotope batteries, hybrid power generation systems and micro-nano integration, and specifically relates to triboluminescence isotope batteries. 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 8%, so its application range is limited and the process of civilian use is relatively difficult

[0005] Therefore, the current research on isotope batteries still needs to be deepened
