DETAILED DESCRIPTION
(14) Reference will be made in detail to examples of the present disclosure. It would be appreciated by those skilled in the art that the following examples are explanatory and cannot be construed to limit the scope of the present disclosure. The specific techniques or conditions not indicated in the examples are performed according to the techniques or conditions described in the literature in the prior art or according to the product instructions. In addition, the reagents or instruments used not indicated with manufacturer are all common products commercially available.
(15) In one aspect, the present disclosure in embodiments provides an isotope battery. According to some embodiments of the present disclosure, the triboluminescence isotope battery includes a housing defining a chamber; and one or more energy conversion devices disposed in the chamber. The energy conversion device includes: a holder, disposed at the housing and in the chamber; a cantilever beam, having a first end region fixed at the holder, and a second end region movable in the chamber; a triboluminescence component, disposed at an upper surface of the first end region of the cantilever beam; a first photoelectric conversion component, disposed at an upper surface of the triboluminescence component; a radioactive source, disposed in the chamber and configured to emit a first charge and a second charge which have opposite polarity; a first charge collecting component, configured to enrich the first charge and disposed at a lower surface of the second end region of the cantilever beam; a second charge collecting component, configured to enrich the second charge and allow the second charge enriched thereby to attract the first charge enriched by the first charge collecting component such that the second end region of the cantilever beam moves toward the second charge collecting component; a first thermoelectric conversion component, disposed at an upper surface of the second end region of the cantilever beam; and a heat dissipation component, disposed at a surface of the first thermoelectric conversion component. Therefore, the isotope battery can break through the technologic bottleneck of single energy conversion and large energy loss existing in the traditional isotope batteries, with features of high energy conversion efficiency, excellent working stability and high micro/nano integration.
(16) According to the isotope battery of the present disclosure, the radioactive source (also called as radioisotope) emits decayed rays into energy conversion devices (such as, a charge enrichment component, a photoelectric conversion component and a thermoelectric conversion component) which can convert decay energy of radioactive source into electric energy. Specifically, the conversion process for electrical output of the isotope battery is as follows. The radioactive source emits a first charge and a second charge which have opposite polarity. The first charge collecting component disposed at the lower surface of the second end region of the cantilever beam enriches the first charge, and the second charge collecting component enriches the second charge and allows the second charge enriched thereby to attract the first charge enriched by the first charge collecting component such that the second end region of the cantilever beam moves toward the second charge collecting component under the Coulomb force. The triboluminescence component generates a mechanical deformation with the movement of the cantilever beam, and thus emitting specific spectrum which will be converted into electrical output via the first photoelectric conversion component disposed at the upper surface of the triboluminescence component. However, when the first charge collecting component contacts with the second charge collecting component, the coulomb force disappears, and then the first and second charge collecting components separate (i.e. forming a cycle). Thus, the electrical output is generated by such reciprocating cycles. Further, the first thermoelectric conversion component converts the thermal difference between the cantilever beam and the external temperature of the heat dissipation component into electrical output.
(17) According to some embodiments, the specific structure, shape and the like of the housing can be flexibly selected according to actual needs. In some embodiments, the housing is shaped as a cylindrical shape and is further provided with a first gasket and a second gasket at two ends respectively, such that a sealed chamber is formed in the housing. For the energy conversion device adjacent to the first gasket, the first end region of the cantilever beam extends to and is embedded in the first gasket. The second gasket is provided with a nozzle controlled by a valve, such that the sealed chamber can communicate with the outside by the nozzle. In some embodiments, the housing is made of aluminum silicate. The first gasket and the second gasket can be made of same materials provided the materials have mechanical strength, heat insulation effect and radiation shielding effect for the housing, such as carbon fiber, rubber and the like. The first and second gaskets are useful in buffing the mechanical stress and thermal stress existing in the housing, thus improving the work stability and environmental adaptability for the triboluminescence isotope battery. The nozzle has an opening in a shape of round hole, and the valve can be a ball valve, thereby allowing the generation of a vacuum environment in the sealed chamber.
(18) According to some embodiments, the inner surface of the housing is further provided with a buffing component. In some embodiments, the buffing component can be made of a graphite-epoxy thermally conductive composite (GEC), thereby thermally insulating and fixing the connector between the electrodes and energy conversion devices as well as the outer surface of energy conversion devices, but also buffing the mechanical stress and thermal stress existing in the housing, with improved stability and environmental adaptability in extreme environments. In some embodiments, the buffing component can be disposed between the first gasket and the second gasket. The components disposed at the housing (such as the radioactive source, the energy conversion device, the second charge collecting component and the like) can be disposed on the buffing component or disposed through the buffing component and on the surface of the housing.
(19) According to some embodiments, the inner surface of the housing can be coated with a nano-lead plexiglass composite to improve the radiation shielding effect and safety of the triboluminescence isotope battery. The thickness of the nano-lead plexiglass composite can be flexibly adjusted as the requirements of actual working environment. Thus, the triboluminescence isotope battery of the present disclosure exhibits favorable radiation shielding effect and safety.
(20) According to some embodiments, the specific structure, material, shape and the like of the cantilever beam can be flexibly selected as the actual needs. In some embodiments, the cantilever beam can be made of a material such as Si, Au or Cu, with a wide source and low cost, good mechanical property and fatigue resistance. Thus, the prepared triboluminescence isotope battery displays good stability and long service life.
(21) According to some embodiments, the first charge collecting component and the second charge collecting component can be a metal film layer which is made of a metal selected from Au, Pd, Pt, Al, Cu, Ni and Ti. In some embodiments, the radioactive source and the second charge collecting component are integrated as a single component, that is the single component exhibits the function of both the radioactive source and the second charge collecting component.

(23) It should be noted, when the radioactive source is represented in (C.sub.4H.sub.3.sup.3H.sub.5-).sub.n, the radioactive source is tritiated poly(l-ethylethylene), where n represents the polymerization degree, without limitation for specific values. The polymerization degree of the radioactive source can be flexibly selected by those skilled in the art according to application fields or specific parameters of the triboluminescence isotope battery.
(24) According to some embodiments, the radioactive source can be a radioisotope film. Its activity, size and the like can be controlled according to the requirements of output voltage and current in actual application.
(25) According to some embodiments, the radioactive source can be flexibly set at a specific position as per actual conditions provided that it can radiate energy which will be converted into electrical energy output. In the embodiments, the radioactive source can be arranged in two ways. In a first way, the radioactive source and the first charge collection component are disposed correspondingly, where the first charge collecting component is configured to enrich charges by directly absorbing the particles radiated by the radioactive source, and the second charge collecting component is configured to contact with the radioactive source directly, for example, the radioactive source is disposed at a surface of the second charge collecting component away from the housing. In a second way, the radioactive source and the first charge collection component are not correspondingly disposed, and the first charge collection component and the second charge collecting component are respectively connected to energy conversion components to enrich electric charges, for example, the radioactive source is clamped in a cavity defined by the hollow structure of the holder, the upper surface of the radioactive source is disposed with a second energy conversion component which is electrically connected to the first charge collecting component, and the lower surface of the radioactive source is disposed with a third energy conversion component which is electrically connected to the second charge collecting component.
(26) According to some embodiments, the triboluminescence isotope battery further comprises a first energy conversion component when the radioactive source is disposed in the first way. The first energy conversion component is disposed at the side of the radioactive source away from the first charge collection component. Therefore, the first energy conversion component can absorb the energy radiated from the side of the radioactive source close to the housing and convert the energy into electric energy output, thereby effectively improving the energy conversion efficiency. Use of a variety of energy conversion methods can overcome the problems of single energy conversion and large energy loss.
(27) According to some embodiments, the first energy conversion component is any one of a second thermoelectric conversion component, a first radio-voltaic component and a first radioluminescence component. Therefore, use of a variety of energy conversion methods can overcome the problems of single energy conversion and large energy loss, with improved energy conversion efficiency to a large extent, and meeting the requirements of low carbon, environmental protection, integration efficiency, economic and universality.
(28) According to some embodiments, the second and third energy conversion components each are any one of a third thermoelectric conversion component, a second radio-voltaic component and a second radioluminescence component when the radioactive source is disposed in the second way. Therefore, use of a variety of energy conversion methods can overcome the problems of single energy conversion and large energy loss, with improved energy conversion efficiency to a large extent, and meeting the requirements of low carbon, environmental protection, integration efficiency, economic and universality.

(35) Referring to the drawings, the triboluminescence isotope battery of the present disclosure is described as below.
(36) In one embodiment of the present disclosure, referring to FIG. 1 to FIG. 5, the triboluminescence isotope battery is illustrated as below. The triboluminescence isotope battery formed as a cylindrical structure, includes a housing 15, defining a chamber 16; and an energy conversion device disposed in the chamber 16. The energy conversion device includes a holder 13, a cantilever beam 11, a triboluminescence component 31, a first photoelectric conversion component 32, a radioactive source 21, a first charge collecting component 25, a second charge collecting component 23, a first thermoelectric conversion component 42 and a heat dissipation component 41. Specifically, the housing 15 is further provided with a first gasket 12 and a second gasket 17 at two ends respectively. The cantilever beam 11 has a first end region fixed at the holder 13, and a second end region movable in the chamber 16, in which the first end region of the cantilever beam 11 extends to and is embedded in the first gasket 12 or is fixed at the housing 15. The triboluminescence component 31 is disposed at an upper surface of the first end region of the cantilever beam 11. The first photoelectric conversion component 32 is disposed at an upper surface of the triboluminescence component 31, and further provided with a first output terminal 34 which is electrically connected to the first photoelectric conversion component 32 via a first output wire 33 to output electric energy converted from lights. The radioactive source 21 is disposed in the chamber 16 and configured to emit a first charge (such as a negative charge 24) and a second charge with an opposite polarity to the first charge (such as a positive charge 22). According to this embodiment, the radioactive source 21 is a radioisotope film and disposed on the surface of the second charge collecting component 23. The first charge collecting component 25 is configured to enrich the first charge and disposed at a lower surface of the second end region of the cantilever beam 11. The second charge collecting component 23 is configured to enrich the second charge and allow the second charge enriched thereby to attract the first charge enriched by the first charge collecting component 25 such that the second end region of the cantilever beam 11 moves toward the second charge collecting component 23 by the Coulomb force. When the first charge collecting component 25 contacts with the second charge collecting component 23, the coulomb force disappears, and then the first and second charge collecting components separate (i.e. forming a cycle). Thus, the electrical output is generated by such reciprocating cycles. According to this embodiment, the second charge collecting component 23 is disposed at the housing 15 and corresponds to the first charge collecting component 25. The first thermoelectric conversion component 42 is disposed at an upper surface of the second end region of the cantilever beam 11, and a heat dissipation component 41 is disposed at a surface of the first thermoelectric conversion component 42. The first thermoelectric conversion component 42 is further provided with a second output terminal 44 which is electrically connected to the first thermoelectric conversion component 42 via a second output wire 43 to output electric energy converted from the thermal difference between the first thermoelectric conversion component 42 and the external temperature of the heat dissipation component 41. The holder 13 is arranged between a lower surface of the first end region of the cantilever beam 11 and the housing 15. A buffing component 14 is further disposed on the inner surface of the housing 15 tightly, particularly disposed between the first gasket 12 and the second gasket 17. The second gasket 17 is provided with a nozzle 18 controlled by a valve 19 to allow the formation of a vacuous chamber. The nozzle 18 can be disposed at a center of the second gasket 17.
(37) With combination to FIG. 2, the triboluminescence isotope battery of the present disclosure realizes the electrical output as below. The radioactive source 21 emits a first charge and a second charge which have opposite polarity. The first charge collecting component 25 disposed at the lower surface of the second end region of the cantilever beam 11 enriches the first charge, and the second charge collecting component 23 enriches the second charge and allows the second charge enriched thereby to attract the first charge enriched by the first charge collecting component 25 such that the second end region of the cantilever beam 11 moves toward the second charge collecting component 23 under the Coulomb force. The triboluminescence component 31 generates a mechanical deformation with the movement of the cantilever beam 11, and thus emitting specific spectrum which can be converted into electrical output via the first photoelectric conversion component 32 disposed at the upper surface of the triboluminescence component 31. However, when the first charge collecting component 25 contacts with the second charge collecting component 23, the coulomb force disappears, and then the first and second charge collecting components separate (i.e. forming a cycle). Thus, the electrical output is generated by such reciprocating cycles. Further, the first thermoelectric conversion component 42 converts the thermal difference between the cantilever beam 11 and the external temperature of the heat dissipation component 41 into electrical output.

When the first charge collecting component 25 contacts with the second charge collecting component 23, the coulomb force disappears, and then the first and second charge collecting components separate (i.e. forming a cycle). Thus, the electrical output is generated by such reciprocating cycles. According to this embodiment, the second charge collecting component 23 is disposed at the housing and includes a first surface close to the first charge collecting component 25 and a second surface away from the first charge collecting component 25. The radioactive source 21 is disposed at the first surface of the second charge collecting component 23.

According to this embodiment, the first energy conversion component is a second thermoelectric conversion component 42a, which is further provided with a third output terminal 44a electrically connected to the second thermoelectric conversion component 42a via a third output wire 43a. Thus, the second thermoelectric conversion component 42a can absorb heat radiated from the side of the radioactive source 21 close to the housing 15 and convert the heat into an electrical output, thereby effectively improving the energy conversion efficiency and overcoming the deficiency of single transduction and large energy loss. The first thermoelectric conversion component 42 is disposed at an upper surface of the second end region of the cantilever beam 11, and a heat dissipation component 41 is disposed at a surface of the first thermoelectric conversion component 42. The first thermoelectric conversion component 42 is further provided with a second output terminal 44 which is electrically connected to the first thermoelectric conversion component 42 via a second output wire 43 to output electric energy converted from the thermal difference between the first thermoelectric conversion component 42 and the external temperature of the heat dissipation component 41.

Thus, the first radio-voltaic component 42b can absorb the particles radiated from the side of the radioactive source 21 close to the housing 15 and convert the radiation energy into electrical output, thereby effectively improving the energy conversion efficiency and overcoming the deficiency of single transduction and large energy loss. The first charge collecting component 25 is configured to enrich the first charge 24 emitted by the radioactive source 21 and disposed at a lower surface of the second end region of the cantilever beam 11. The single component 21 is also configured to enrich the second charge 22 emitted per se and allow the second charge enriched thereby to attract the first charge enriched by the first charge collecting component 25 such that the second end region of the cantilever beam 11 moves toward the single component 21 by the coulomb force. When the first charge collecting component 25 contacts with the single component 21, the coulomb force disappears, and then the first charge collecting component 25 and the single component 21 separate (i.e. forming a cycle). Thus, the electrical output is generated by such reciprocating cycles.
