Embodiment 1

[0038] by 63 Ni isotope source as an example:

[0039] Assuming that the output power of a β-radiation cell produced by one unit is 1mw, a cell with an activity of 1Ci is required. 63 Ni isotope source, its specification is length 1.4cm, width 1.4cm, thickness 0.1mm.

[0040] in the above specification 63 The Ni isotope source is covered with a stainless steel closed cuboid as the collector, and a wire is connected as the negative electrode. The stainless steel closed cuboid has an inner length of 2cm, an inner width of 2cm, and an inner thickness of 2.1mm, and its strength should be able to withstand a standard atmospheric pressure. Apply a thickness of about 10 to the stainless steel material on the inner surface of the cuboid －2 mm of sodium metal or other group Ι metal elements (lithium, potassium, etc.), and the coated sodium metal layer and 63 The Ni isotope sources are separated and fixed by quartz cotton insulating buffer liners.

[0041] Then the above-mentioned...

Abstract

The invention relates to the technical field of nuclear batteries, and particularly discloses a 63Ni or 147Pm isotope source beta radiation battery of a vacuum medium and an application system of the 63Ni or 147Pm isotope source beta radiation battery. The battery comprises a 63Ni or 147Pm radioactive isotope source, a sealing shell, a positive electrode and a negative electrode, the sealing shell is made of stainless steel, the positive electrode extends into a vacuum inner cavity in the sealing shell through an insulating sealing ring, the 63Ni or 147Pm radioactive isotope source is arranged in the vacuum inner cavity and connected with the positive electrode, and the inner wall of the sealing shell is uniformly coated with a coating layer of group I metal elements. The whole beta radiation battery disclosed by the invention is simple in internal structure, and no semiconductor is arranged in the whole beta radiation battery, so that a series of problems of output attenuation and the like caused by the fact that a semiconductor in an existing nuclear battery is easy to damage a threshold by radiation are effectively avoided. In addition, the application system alternately charges the secondary lithium battery through parallel connection and direct current transformation, the purpose of continuously collecting energy for centralized use is achieved, and the application value is very high.

Description

technical field [0001] The invention relates to the technical field of nuclear batteries, and specifically discloses a vacuum medium 63 Ni or 147 Pm isotope source β radiation battery and its application system. Background technique [0002] Micro-power energy is an important basis for micro-motor systems (MEMS), and its research and development are mainly focused on the following aspects: micro-internal combustion turbine engines and generator systems, micro-fuel cells, micro-lithium batteries, micro-solar cells, micro-Zn- Ni battery, micro thermoelectric battery and isotope micro battery, etc. [0003] At present, the isotope β-radiation voltaic effect microbattery occupies a very important position in the micro-electromechanical system, but the output voltage and power of the isotope β-radiation voltaic effect microbattery are very low, the semiconductor band gap, and the threshold of radiation damage lead to output attenuation. , and factors such as materials and devi...
