Under the conditions of environmental mechanicses, under such as more than 10000g impact or high heat design point, the electrolyte in barrier film and negative pole material
Material LiB alloy still may overflow trickling, cause short circuit.
Traditional single cell of thermo battery structure is as shown in figure 1, its operation principle is：After thermal cell activation, in pyrotechnics
In the presence of thermal source, electrolyte and negative pole Flashmelt, so as to electrochemical system is built, export electric energy.In activation, electricity
Solution matter and negative material are changed into liquid phase from solid phase, volumetric expansion, and under higher stack pressure, the restrictor ring in conventional batteries is not
Electrolyte and LiB alloy can be held onto completely, the two all may between barrier film and cathode contact face overflow and go out to cause short circuit（Figure
Overfall 6 shown in 1）.
Utility model content
The technical problems to be solved in the utility model is：A kind of new single cell of thermo battery is provided, by strengthening current limliting
Ring thickness forms tubbiness semi-closed structure, is embedded in restrictor ring formation integration monomer battery by reducing compact size, with solution
The technical barrier that certainly electrolyte and negative material trickle in thermal cell barrier film.
The technical solution of the utility model：A kind of single cell of thermo battery, including flow collection sheet, negative plate, containing positive pole and
The composite sheet of barrier film, and the restrictor ring made of isolation material, wherein, restrictor ring is bonded on flow collection sheet, and negative plate is placed in
Restrictor ring inner bottom part, and contact with flow collection sheet, the composite sheet is placed in restrictor ring, and is located above negative plate, in restrictor ring
Gap is left between inwall and composite sheet and negative plate outer wall.
The current limliting ring thickness is 0.9 ~ 1.3 times of composite sheet and negative plate gross thickness.

The restrictor ring external diameter is identical with flow collection sheet outside dimension.
The isolation material is asbestos or mica.
The beneficial effects of the utility model are：Barreled semi-closed structure that the utility model is built by restrictor ring, embedded
The integration monomer battery structure that pole piece is formed.Conventional thermoelectric pond monomer battery structure is compared, is had the advantage that：
1st, the tubbiness semi-closed structure that restrictor ring is formed eliminates overfall, not only limits the trickling of negative pole LiB alloy,
And the trickling of the electrolyte in barrier film is limited, with higher reliability.
2nd, the single cell of thermo that the utility model is provided is semiclosed integral structure, is totally different from same size
Composite sheet+semi-enclosed negative pole modular construction, reduce battery component quantity, more reliable in structure, be conducive to enhancing to exceed
Carry lower environmental mechanicses performance.
3rd, the single cell of thermo that the utility model is provided has higher safe adaptability, as restrictor ring is present with pole piece
Certain interval, not only can provide the tolerance existed when monomer is assembled, and can build electrolyte or barrier film under extreme condition
Packing space in trickling.
4th, current limliting ring thickness and pole piece in the single cell of thermo that the utility model is provided（Composite sheet+negative plate）Gross thickness phase
Closely, be not in the excessive situation of local pressure, the overlap joint that can be better protected between ultra-thin cell, widen monomer electricity
The practical space in pond.
In sum, the utility model compared with prior art, can strengthen the security performance of battery, widen thermal cell heat
Amount scope of design, can preferably meet hot environment and high overload thermal cell use requirement.
