Using tritium as radioactivity excitaton source, for exciting PN junction electron transition, using liquid titanium dioxide tritium as the thing of tritium
Matter form, between 50GBq-400GBq, GBq is GBq for a kind of unit to the consumption of the radioactivity of tritium,
The abbreviation of Gigabit Becquerel.
Because tritium oxide chemical property itself and pure water do not have much differences, can be by water-absorption particle in P-type semiconductor
Fixing, the solid titanium dioxide tritium for 50GBq 400GBq by radioactivity, be configured to 1ml about solution, seal and be cooled to ice
Point freezes standby.
Then vacuum drying mode, the film being loaded with p-type and N-type semiconductor that drying has prepared are adopted.In an air
(solution evaporation is prevented), the one milliliter of radioactivity preparing of thawing is 50GBq 400GBq's in the environment of 2 DEG C -5 DEG C of pressure
Titanium dioxide tritium solution, and be uniformly sprayed on the dried PEDOT conductive film scribbling Nano titanium dioxide.To prepare
Good oxidation copper face is fitted with scribbling titanium dioxide one side, uses 50N/M2Power pressed.But, pressure is crossed conference and is made oxidation
Copper thin film is separated with Copper Foil and comes off, and increases the internal resistance of battery, too small then PN junction loose contact, and the power of battery can be caused to decline.
S106：Encapsulation, radioprotective are processed.
Bond glue in the uniform last layer that applies of conductive membrane layer 103 one side, a diameter of 0.1mm thin copper wire electrode is inserted
It is fixed with electric silica gel outside conductive film, afterwards the electric insulation layer made 104 is bonded at described conductive membrane layer 103
Outside, using 50N/M2Pressure pressing 3-4 minute.The copper being 0.1mm with electric silica gel fixed diameter on lower floor's Copper Foil
Silk is fixed on the outside of Copper Foil.
At this moment flexible isotope battery 100 is crimped, puts in cylindrical mold afterwards, the shape of grinding tool with
For cylindrical, put into and carry out battery structure airtight sealing with epoxy resin, dry in the shade.
The battery winding of good seal also needs to do radioprotective process in outside, because the radioelement adopting is tritium, tritium institute
The radiation of transmitting is easily by mental retardation shellfish spy's ray of Metal absorption.It is packaged in outside wrapper 107, be shaped as justifying
Cylinder shape, the material of its wrapper 107 can adopt aluminum.
In sum, flexible isotope battery of the present utility model can be using radiosiotope generation with energy
The particle beam irradiation of amount arrives the PN junction of ready-made space-charge region, excites PN junction generation electric potential difference generating electricity, and using covering
The Copper Foil having copper oxide is coated on flexible conductive membrane layer as N-type semiconductor layer, and by N-type semiconductor layer
Surface, whole isotope battery can bend, and can increase the area of PN junction to a greater extent, to improve generated output, uses
When impact resistance stronger.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.It should be noted that
Arrive：Similar label and letter represent similar terms, therefore, once being determined in a certain Xiang Yi accompanying drawing in following accompanying drawing
Justice, then do not need it to be defined further and explains in subsequent accompanying drawing.
